Detailed Description

It represents a single node in the document tree. While all objects implementing the DOMNode interface expose methods for dealing with children, not all objects implementing the DOMNode interface may have children. For example, DOMText nodes may not have children, and adding children to such nodes results in a DOMException being raised.

The attributes nodeName , nodeValue and attributes are included as a mechanism to get at node information without casting down to the specific derived interface. In cases where there is no obvious mapping of these attributes for a specific nodeType (e.g., nodeValue for an DOMElement or attributes for a DOMComment ), this returns null . Note that the specialized interfaces may contain additional and more convenient mechanisms to get and set the relevant information.

The values of nodeName , nodeValue , and attributes vary according to the node type as follows:

Interface nodeName nodeValue attributes
DOMAttr name of attribute value of attribute null
DOMCDATASection «cdata-section» content of the CDATA Section null
DOMComment «comment» content of the comment null
DOMDocument «document» null null
DOMDocumentFragment «document-fragment» null null
DOMDocumentType document type name null null
DOMElement tag name null NamedNodeMap
DOMEntity entity name null null
DOMEntityReference name of entity referenced null null
DOMNotation notation name null null
DOMProcessingInstruction target entire content excluding the target null
DOMText «text» content of the text node null

Member Function Documentation

virtual DOMNode* DOMNode::appendChild ( DOMNode * newChild ) [pure virtual]

Adds the node newChild to the end of the list of children of this node.

If the newChild is already in the tree, it is first removed. Parameters:

newChild The node to add.If it is a DOMDocumentFragment object, the entire contents of the document fragment are moved into the child list of this node

Returns: The node added. Exceptions:

DOMException HIERARCHY_REQUEST_ERR: Raised if this node is of a type that does not allow children of the type of the newChild node, or if the node to append is one of this node’s ancestors.
WRONG_DOCUMENT_ERR: Raised if newChild was created from a different document than the one that created this node.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node or the node being appended is readonly.

Since: DOM Level 1

virtual DOMNode* DOMNode::cloneNode ( bool deep ) const [pure virtual]

Returns a duplicate of this node.

This function serves as a generic copy constructor for nodes.

The duplicate node has no parent ( parentNode returns null .).
Cloning an DOMElement copies all attributes and their values, including those generated by the XML processor to represent defaulted attributes, but this method does not copy any text it contains unless it is a deep clone, since the text is contained in a child DOMText node. Cloning any other type of node simply returns a copy of this node. Parameters:

deep If true , recursively clone the subtree under the specified node; if false , clone only the node itself (and its attributes, if it is an DOMElement ).

Returns: The duplicate node. Since: DOM Level 1

virtual short DOMNode::compareTreePosition ( const DOMNode * other ) const [pure virtual]

Compares a node with this node with regard to their position in the tree and according to the document order.

This order can be extended by module that define additional types of nodes.

«Experimental — subject to change» Parameters:

other The node to compare against this node.

Returns: Returns how the given node is positioned relatively to this node. Since: DOM Level 3

virtual DOMNamedNodeMap* DOMNode::getAttributes ( ) const [pure virtual]

Gets a DOMNamedNodeMap containing the attributes of this node (if it is an DOMElement ) or null otherwise.

Since: DOM Level 1

virtual const XMLCh* DOMNode::getBaseURI ( ) const [pure virtual]

The absolute base URI of this node or null if undefined.

This value is computed according to . However, when the DOMDocument supports the feature «HTML» , the base URI is computed using first the value of the href attribute of the HTML BASE element if any, and the value of the documentURI attribute from the DOMDocument interface otherwise.

«Experimental — subject to change»

When the node is an DOMElement , a DOMDocument or a a DOMProcessingInstruction , this attribute represents the properties [base URI] defined in . When the node is a DOMNotation , an DOMEntity , or an DOMEntityReference , this attribute represents the properties [declaration base URI]. Since: DOM Level 3

virtual DOMNodeList* DOMNode::getChildNodes ( ) const [pure virtual]

Gets a DOMNodeList that contains all children of this node.

If there are no children, this is a DOMNodeList containing no nodes. The content of the returned DOMNodeList is «live» in the sense that, for instance, changes to the children of the node object that it was created from are immediately reflected in the nodes returned by the DOMNodeList accessors; it is not a static snapshot of the content of the node. This is true for every DOMNodeList , including the ones returned by the getElementsByTagName method. Since: DOM Level 1

virtual DOMNode* DOMNode::getFirstChild ( ) const [pure virtual]

Gets the first child of this node.

If there is no such node, this returns null . Since: DOM Level 1

virtual DOMNode* DOMNode::getInterface ( const XMLCh * feature ) [pure virtual]

This method makes available a DOMNode ‘s specialized interface.

«Experimental — subject to change» Parameters:

feature The name of the feature requested (case-insensitive).

Returns: Returns an alternate DOMNode which implements the specialized APIs of the specified feature, if any, or null if there is no alternate DOMNode which implements interfaces associated with that feature. Any alternate DOMNode returned by this method must delegate to the primary core DOMNode and not return results inconsistent with the primary core DOMNode such as key , attributes , childNodes , etc. Since: DOM Level 3

virtual DOMNode* DOMNode::getLastChild ( ) const [pure virtual]

Gets the last child of this node.

If there is no such node, this returns null . Since: DOM Level 1

virtual const XMLCh* DOMNode::getLocalName ( ) const [pure virtual]

Returns the local part of the qualified name of this node.

For nodes created with a DOM Level 1 method, such as createElement from the DOMDocument interface, it is null.

Since: DOM Level 2

virtual const XMLCh* DOMNode::getNamespaceURI ( ) const [pure virtual]

Get the namespace URI of this node, or null if it is unspecified.

This is not a computed value that is the result of a namespace lookup based on an examination of the namespace declarations in scope. It is merely the namespace URI given at creation time.

For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as createElement from the DOMDocument interface, this is always null .

Since: DOM Level 2

virtual DOMNode* DOMNode::getNextSibling ( ) const [pure virtual]

Gets the node immediately following this node.

If there is no such node, this returns null . Since: DOM Level 1

virtual const XMLCh* DOMNode::getNodeName ( ) const [pure virtual]

This is also the DOMDocument object used to create new nodes. When this node is a DOMDocument or a DOMDocumentType which is not used with any DOMDocument yet, this is null .

Since: DOM Level 1

virtual DOMNode* DOMNode::getParentNode ( ) const [pure virtual]

Gets the parent of this node.

All nodes, except DOMDocument , DOMDocumentFragment , and DOMAttr may have a parent. However, if a node has just been created and not yet added to the tree, or if it has been removed from the tree, a null DOMNode is returned. Since: DOM Level 1

virtual const XMLCh* DOMNode::getPrefix ( ) const [pure virtual]

Get the namespace prefix of this node, or null if it is unspecified.

Since: DOM Level 2

virtual DOMNode* DOMNode::getPreviousSibling ( ) const [pure virtual]

Gets the node immediately preceding this node.

If there is no such node, this returns null . Since: DOM Level 1

virtual const XMLCh* DOMNode::getTextContent ( ) const [pure virtual]

This attribute returns the text content of this node and its descendants.

When it is defined to be null, setting it has no effect. When set, any possible children this node may have are removed and replaced by a single DOMText node containing the string this attribute is set to. On getting, no serialization is performed, the returned string does not contain any markup. No whitespace normalization is performed, the returned string does not contain the element content whitespaces . Similarly, on setting, no parsing is performed either, the input string is taken as pure textual content.

«Experimental — subject to change»

The string returned is made of the text content of this node depending on its type, as defined below:

Since: DOM Level 3

virtual void* DOMNode::getUserData ( const XMLCh * key ) const [pure virtual]

Retrieves the object associated to a key on a this node.

The object must first have been set to this node by calling setUserData with the same key.

«Experimental — subject to change» Parameters:

key The key the object is associated to.

Returns: Returns the void* associated to the given key on this node, or null if there was none. See also: setUserData Since: DOM Level 3

virtual bool DOMNode::hasAttributes ( ) const [pure virtual]

Returns whether this node (if it is an element) has any attributes.

Returns: true if the node has any children, false if the node has no children. Since: DOM Level 1

virtual DOMNode* DOMNode::insertBefore ( DOMNode * newChild,
DOMNode * refChild
) [pure virtual]

Inserts the node newChild before the existing child node refChild .

If refChild is null , insert newChild at the end of the list of children.
If newChild is a DOMDocumentFragment object, all of its children are inserted, in the same order, before refChild . If the newChild is already in the tree, it is first removed. Note that a DOMNode that has never been assigned to refer to an actual node is == null. Parameters:

newChild The node to insert.
refChild The reference node, i.e., the node before which the new node must be inserted.

Returns: The node being inserted. Exceptions:

DOMException HIERARCHY_REQUEST_ERR: Raised if this node is of a type that does not allow children of the type of the newChild node, or if the node to insert is one of this node’s ancestors.
WRONG_DOCUMENT_ERR: Raised if newChild was created from a different document than the one that created this node.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node or the node being inserted is readonly.

virtual bool DOMNode::isDefaultNamespace ( const XMLCh * namespaceURI ) const [pure virtual]

This method checks if the specified namespaceURI is the default namespace or not.

«Experimental — subject to change» Parameters:

namespaceURI The namespace URI to look for.

Returns: true if the specified namespaceURI is the default namespace, false otherwise. Since: DOM Level 3

virtual bool DOMNode::isEqualNode ( const DOMNode * arg ) const [pure virtual]

Tests whether two nodes are equal.

This method tests for equality of nodes, not sameness (i.e., whether the two nodes are pointers to the same object) which can be tested with DOMNode::isSameNode . All nodes that are the same will also be equal, though the reverse may not be true.
Two nodes are equal if and only if the following conditions are satisfied: The two nodes are of the same type.The following string attributes are equal: nodeName , localName , namespaceURI , prefix , nodeValue , baseURI . This is: they are both null , or they have the same length and are character for character identical. The attributes DOMNamedNodeMaps are equal. This is: they are both null , or they have the same length and for each node that exists in one map there is a node that exists in the other map and is equal, although not necessarily at the same index.The childNodes DOMNodeLists are equal. This is: they are both null , or they have the same length and contain equal nodes at the same index. This is true for DOMAttr nodes as for any other type of node. Note that normalization can affect equality; to avoid this, nodes should be normalized before being compared.
For two DOMDocumentType nodes to be equal, the following conditions must also be satisfied: The following string attributes are equal: publicId , systemId , internalSubset .The entities DOMNamedNodeMaps are equal.The notations DOMNamedNodeMaps are equal.
On the other hand, the following do not affect equality: the ownerDocument attribute, the specified attribute for DOMAttr nodes, the isWhitespaceInElementContent attribute for DOMText nodes, as well as any user data or event listeners registered on the nodes.

«Experimental — subject to change» Parameters:

arg The node to compare equality with.

Returns: If the nodes, and possibly subtrees are equal, true otherwise false . Since: DOM Level 3

virtual bool DOMNode::isSameNode ( const DOMNode * other ) const [pure virtual]

Returns whether this node is the same node as the given one.

This method provides a way to determine whether two DOMNode references returned by the implementation reference the same object. When two DOMNode references are references to the same object, even if through a proxy, the references may be used completely interchangeably, such that all attributes have the same values and calling the same DOM method on either reference always has exactly the same effect.

«Experimental — subject to change» Parameters:

other The node to test against.

Returns: Returns true if the nodes are the same, false otherwise. Since: DOM Level 3

virtual bool DOMNode::isSupported ( const XMLCh * feature,
const XMLCh * version
) const [pure virtual]

Tests whether the DOM implementation implements a specific feature and that feature is supported by this node.

Parameters:

feature The string of the feature to test. This is the same name as what can be passed to the method hasFeature on DOMImplementation .
version This is the version number of the feature to test. In Level 2, version 1, this is the string «2.0». If the version is not specified, supporting any version of the feature will cause the method to return true .

Returns: Returns true if the specified feature is supported on this node, false otherwise. Since: DOM Level 2

virtual const XMLCh* DOMNode::lookupNamespacePrefix ( const XMLCh * namespaceURI,
bool useDefault
) const [pure virtual]

Look up the prefix associated to the given namespace URI, starting from this node.

«Experimental — subject to change» Parameters:

namespaceURI The namespace URI to look for.
useDefault Indicates if the lookup mechanism should take into account the default namespace or not.

Returns: Returns an associated namespace prefix if found, null if none is found and useDefault is false, or null if not found or it is the default namespace and useDefault is true . If more than one prefix are associated to the namespace prefix, the returned namespace prefix is implementation dependent. Since: DOM Level 3

virtual const XMLCh* DOMNode::lookupNamespaceURI ( const XMLCh * prefix ) const [pure virtual]

Look up the namespace URI associated to the given prefix, starting from this node.

«Experimental — subject to change» Parameters:

prefix The prefix to look for. If this parameter is null , the method will return the default namespace URI if any.

Returns: Returns the associated namespace URI or null if none is found. Since: DOM Level 3

virtual void DOMNode::normalize ( ) [pure virtual]

Puts all DOMText nodes in the full depth of the sub-tree underneath this DOMNode , including attribute nodes, into a «normal» form where only markup (e.g., tags, comments, processing instructions, CDATA sections, and entity references) separates DOMText nodes, i.e., there are neither adjacent DOMText nodes nor empty DOMText nodes.

This can be used to ensure that the DOM view of a document is the same as if it were saved and re-loaded, and is useful when operations (such as XPointer lookups) that depend on a particular document tree structure are to be used.

Note: In cases where the document contains DOMCDATASections , the normalize operation alone may not be sufficient, since XPointers do not differentiate between DOMText nodes and DOMCDATASection nodes.

Since: DOM Level 2

virtual void DOMNode::release ( ) [pure virtual]

Called to indicate that this Node (and its associated children) is no longer in use and that the implementation may relinquish any resources associated with it and its associated children.

If this is a document, any nodes it owns (created by DOMDocument::createXXXX()) are also released.

Access to a released object will lead to unexpected result. Exceptions:

DOMException INVALID_ACCESS_ERR: Raised if this Node has a parent and thus should not be released yet.
virtual DOMNode* DOMNode::removeChild ( DOMNode * oldChild ) [pure virtual]

Removes the child node indicated by oldChild from the list of children, and returns it.

Parameters:

oldChild The node being removed.

Returns: The node removed. Exceptions:

DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NOT_FOUND_ERR: Raised if oldChild is not a child of this node.

Since: DOM Level 1

virtual DOMNode* DOMNode::replaceChild ( DOMNode * newChild,
DOMNode * oldChild
) [pure virtual]

Replaces the child node oldChild with newChild in the list of children, and returns the oldChild node.

If newChild is a DOMDocumentFragment object, oldChild is replaced by all of the DOMDocumentFragment children, which are inserted in the same order.

If the newChild is already in the tree, it is first removed. Parameters:

newChild The new node to put in the child list.
oldChild The node being replaced in the list.

Returns: The node replaced. Exceptions:

DOMException HIERARCHY_REQUEST_ERR: Raised if this node is of a type that does not allow children of the type of the newChild node, or it the node to put in is one of this node’s ancestors.
WRONG_DOCUMENT_ERR: Raised if newChild was created from a different document than the one that created this node.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node or the new node is readonly.
NOT_FOUND_ERR: Raised if oldChild is not a child of this node.

Since: DOM Level 1

virtual void DOMNode::setNodeValue ( const XMLCh * nodeValue ) [pure virtual]

Sets the value of the node.

Any node which can have a nodeValue ( See also: getNodeValue) will also accept requests to set it to a string. The exact response to this varies from node to node — Attribute, for example, stores its values in its children and has to replace them with a new Text holding the replacement value. For most types of Node, value is null and attempting to set it will throw DOMException(NO_MODIFICATION_ALLOWED_ERR). This will also be thrown if the node is read-only. Since: DOM Level 1

virtual void DOMNode::setPrefix ( const XMLCh * prefix ) [pure virtual]

Set the namespace prefix of this node.

Note that setting this attribute, when permitted, changes the nodeName attribute, which holds the qualified name, as well as the tagName and name attributes of the DOMElement and DOMAttr interfaces, when applicable.

Note also that changing the prefix of an attribute, that is known to have a default value, does not make a new attribute with the default value and the original prefix appear, since the namespaceURI and localName do not change. Parameters:

prefix The prefix of this node.

Exceptions:

DOMException INVALID_CHARACTER_ERR: Raised if the specified prefix contains an illegal character.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NAMESPACE_ERR: Raised if the specified prefix is malformed, if the namespaceURI of this node is null , if the specified prefix is «xml» and the namespaceURI of this node is different from «http://www.w3.org/XML/1998/namespace», if this node is an attribute and the specified prefix is «xmlns» and the namespaceURI of this node is different from «http://www.w3.org/2000/xmlns/», or if this node is an attribute and the qualifiedName of this node is «xmlns».

Since: DOM Level 2

virtual void DOMNode::setTextContent ( const XMLCh * textContent ) [pure virtual]

This attribute returns the text content of this node and its descendants.

When it is defined to be null, setting it has no effect. When set, any possible children this node may have are removed and replaced by a single DOMText node containing the string this attribute is set to. On getting, no serialization is performed, the returned string does not contain any markup. No whitespace normalization is performed, the returned string does not contain the element content whitespaces . Similarly, on setting, no parsing is performed either, the input string is taken as pure textual content.

«Experimental — subject to change»

The string returned is made of the text content of this node depending on its type, as defined below:

Node type Content
ELEMENT_NODE, ENTITY_NODE, ENTITY_REFERENCE_NODE, DOCUMENT_FRAGMENT_NODE concatenation of the textContent attribute value of every child node, excluding COMMENT_NODE and PROCESSING_INSTRUCTION_NODE nodes
ATTRIBUTE_NODE, TEXT_NODE, CDATA_SECTION_NODE, COMMENT_NODE, PROCESSING_INSTRUCTION_NODE nodeValue
DOCUMENT_NODE, DOCUMENT_TYPE_NODE, NOTATION_NODE null

Exceptions:

DOMException NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.
DOMException DOMSTRING_SIZE_ERR: Raised when it would return more characters than fit in a DOMString variable on the implementation platform.

Since: DOM Level 3

virtual void* DOMNode::setUserData ( const XMLCh * key,
void * data,
DOMUserDataHandler * handler
) [pure virtual]

Associate an object to a key on this node.

The object can later be retrieved from this node by calling getUserData with the same key.

Deletion of the user data remains the responsibility of the application program; it will not be automatically deleted when the nodes themselves are reclaimed.

Both the parameter data and the returned object are void pointer, it is applications’ responsibility to keep track of their original type. Casting them to the wrong type may result unexpected behavior.

DomNode->replace_node

(No version information available, might be only in CVS)

DomNode->replace_node — Replaces node

Description

(PHP 4.2) This function replaces an existing node with the passed new node. Before the replacement newnode is copied if it has a parent to make sure a node which is already in the document will not be inserted a second time. This behaviour enforces doing all modifications on the node before the replacement or to refetch the inserted node afterwards with functions like domnode_first_child(), domnode_child_nodes() etc..

(PHP 4.3) This function replaces an existing node with the passed new node. It is not copied anymore. If newnode was already inserted in the document it is first unlinked from its existing context. If the replacement succeeds the old node is returned.

object DomNode->replace_node (object newnode)

Эта функция заменяет существующий узел новым переданным. Перед замещением newnode копируется, если имеет предка, чтобы гарантировать, что узел, который который уже имеется в документе, не будет вставлен вторично. Это поведение форсирует все модификации узла до замещения или повторное получение вставляемого узла затем с помощью функций вроде DomNode_first_child() , DomNode_child_nodes() etc.

Description object DomNode->replace_node ( object newnode)

(PHP 4.2) This function replaces an existing node with the passed new node. Before the replacement newnode is copied if it has a parent to make sure a node which is already in the document will not be inserted a second time. This behaviour enforces doing all modifications on the node before the replacement or to refetch the inserted node afterwards with functions like domnode_first_child() , domnode_child_nodes() etc..

How can I replace a DOMNode with a DOMNodeList in PHP?

Up until now I’ve been able to replace nodes pretty easily because I’ve only needed to replace them 1:1 and because they were only text. I was using something like this:

The problem now is that I need to accept strings that may or may not include some HTML. For instance I can no longer use createTextNode() with the string:

because I’ll end up with a mix of html entities in my actual html. Nor can I do this one:

I’ve revised my code to the following, the first part creates a new dom node by importing the text/html mix with a wrapper I can use to pull it back out as a node with, and the second part imports the new DOMNode, and replaces the original node with it:

The problem that remains, which I can’t get my head around, is that the document now contains all of the new node including the element, but it’s the only way to do the 1:1 replacement because replaceChild() requires the parameter to be a DOMNode, so I can’t use the nodes DOMNodeList of children directly.

What is the easiest solution to either remove the node but keep its child nodes (the actual content I want), or to replace the original node with multiple nodes directly?

EDIT: The complete intention would be to take:

then replace the

and replace the

. and in my original question, in the code example, $element would represent the
