It took me forever to find a mapping for the XML_*_NODE constants. So I thought, it’d be handy to paste it here:

1 XML_ELEMENT_NODE
2 XML_ATTRIBUTE_NODE
3 XML_TEXT_NODE
4 XML_CDATA_SECTION_NODE
5 XML_ENTITY_REFERENCE_NODE
6 XML_ENTITY_NODE
7 XML_PROCESSING_INSTRUCTION_NODE
8 XML_COMMENT_NODE
9 XML_DOCUMENT_NODE
10 XML_DOCUMENT_TYPE_NODE
11 XML_DOCUMENT_FRAGMENT_NODE
12 XML_NOTATION_NODE

You cannot simply overwrite $textContent, to replace the text content of a DOMNode, as the missing readonly flag suggests. Instead you have to do something like this:

-> removeChild ( $node -> firstChild );
$node -> appendChild (new DOMText ( ‘new text content’ ));

?>

This example shows what happens:

= DOMDocument :: loadXML ( ‘ old content ‘ );
$node = $doc -> getElementsByTagName ( ‘node’ )-> item ( 0 );
echo «Content 1: » . $node -> textContent . «\n» ;

$node -> textContent = ‘new content’ ;
echo «Content 2: » . $node -> textContent . «\n» ;

$newText = new DOMText ( ‘new content’ );

$node -> appendChild ( $newText );
echo «Content 3: » . $node -> textContent . «\n» ;

$node -> removeChild ( $node -> firstChild );
$node -> appendChild ( $newText );
echo «Content 4: » . $node -> textContent . «\n» ;

Content 1: old content // starting content
Content 2: old content // trying to replace overwriting $node->textContent
Content 3: old contentnew content // simply appending the new text node
Content 4: new content // removing firstchild before appending the new text node

If you want to have a CDATA section, use this:

= DOMDocument :: loadXML ( ‘ old content ‘ );
$node = $doc -> getElementsByTagName ( ‘node’ )-> item ( 0 );
$node -> removeChild ( $node -> firstChild );
$newText = $doc -> createCDATASection ( ‘new cdata content’ );
$node -> appendChild ( $newText );
echo «Content withCDATA: » . $doc -> saveXML ( $node ). «\n» ;
?>

For clarification:
The assumingly ‘discoverd’ by previous posters and seemingly undocumented methods (.getElementsByTagName and .getAttribute) on this class (DOMNode) are in fact methods of the class DOMElement, which inherits from DOMNode.

This class has a getAttribute method.

Assume that a DOMNode object $ref contained an anchor taken out of a DOMNode List. Then

would isolate the url associated with the href part of the anchor.

In response to: alastair dot dallas at gmail dot com about «#text» nodes.
«#text» nodes appear when there are spaces or new lines between end tag and next initial tag.

«data» childNodes has 4 childs:
— age = 10
— #text = spaces
— other = 20
— #text = spaces

The issues around mixed content took me some experimentation to remember, so I thought I’d add this note to save others time.

When your markup is something like:


and

    and the nodeValue for both

s yields the text you expect.

But when your markup is more like

This is bold and this is italic.

, you realize that the nodeValue for XML_ELEMENT_NODEs is not reliable. In this case, you need to look at the

‘s child nodes. For this example, the

has children: #text, , #text, , #text.

In this example, the nodeValue of and is the same as their #text children. But you could have markup like:

This is bold and bold italic, you see?

. In this case, you need to look at the children of , which will be #text, , because the nodeValue of will not be sufficient.

XML_TEXT_NODEs have no children and are always named ‘#text’. Depending on how whitespace is handled, your tree may have «empty» #text nodes as children of and elsewhere.

Attributes are nodes, but I had forgotten that they are not in the tree expressed by childNodes. Walking the full tree using childNodes will not visit any attribute nodes.

And apparently also a setAttribute method too:

$node->setAttribute( ‘attrName’ , ‘value’ );

This class apparently also has a getElementsByTagName method.

I was able to confirm this by evaluating the output from DOMNodeList->item() against various tests with the is_a() function.

Yet another DOMNode to php array conversion function.
Other ones on this page are generating too «complex» arrays; this one should keep the array as tidy as possible.
Note: make sure to set LIBXML_NOBLANKS when calling DOMDocument::load, loadXML or loadHTML
See: http://be2.php.net/manual/en/libxml.constants.php

/**
* Returns an array representation of a DOMNode
* Note, make sure to use the LIBXML_NOBLANKS flag when loading XML into the DOMDocument
* @param DOMDocument $dom
* @param DOMNode $node
* @return array
*/
function nodeToArray ( $dom , $node ) <
if(! is_a ( $dom , ‘DOMDocument’ ) || ! is_a ( $node , ‘DOMNode’ )) <
return false ;
>
$array = false ;
if( empty( trim ( $node -> localName ))) < // Discard empty nodes
return false ;
>
if( XML_TEXT_NODE == $node -> nodeType ) <
return $node -> nodeValue ;
>
foreach ( $node -> attributes as $attr ) <
$array [ ‘@’ . $attr -> localName ] = $attr -> nodeValue ;
>
foreach ( $node -> childNodes as $childNode ) <
if ( 1 == $childNode -> childNodes -> length && XML_TEXT_NODE == $childNode -> firstChild -> nodeType ) <
$array [ $childNode -> localName ] = $childNode -> nodeValue ;
> else <
if( false !== ( $a = self :: nodeToArray ( $dom , $childNode ))) <
$array [ $childNode -> localName ] = $a ;
>
>
>
return $array ;
>
?>

It would be helpful if docs for concrete properties mentioned readonly status of some properties:
«
ownerDocument

The DOMDocument object associated with this node.

Here is a little function that truncates a DomNode to a specified number of text characters. I use it to generate HTML excerpts for my blog entries.


function makehtmlexcerpt ( DomNode $html , $excerptlength )
<
$remove = 0 ;
$htmllength = strlen ( html_entity_decode ( $html -> textContent , ENT_QUOTES , ‘UTF-8’ ));
$truncate = $htmllength — $excerptlength ;
if( $htmllength > $excerptlength )
<
if( $html -> hasChildNodes ())
<
$children = $html -> childNodes ;
for( $counter = 0 ; $counter $children -> length ; $counter ++)
<
$child = $children -> item ( $children -> length — ( $counter + 1 ));
$childlength = strlen ( html_entity_decode ( $child -> textContent , ENT_QUOTES , ‘UTF-8’ ));
if( $childlength $truncate )
<
$remove ++;
$truncate = $truncate — $childlength ;
>
else
<
$child = makehtmlexcerpt ( $child , $childlength — $truncate );
break;
>
>
if( $remove != 0 )
<
for( $counter = 0 ; $counter $remove ; $counter ++)
<
$html -> removeChild ( $html -> lastChild );
>
>
>
else
<
if( $html -> nodeName == ‘#text’ )
<
$html -> nodeValue = substr ( html_entity_decode ( $html -> nodeValue , ENT_QUOTES , ‘UTF-8’ ), 0 , $htmllength — $truncate );

return $html ;

Select the next node of the selected node in PHP DOM?

So far I’m working on a HTML file like this

I want to select the next node of every «div» which has its name equal to «node» and I try :

But I just get an error

Fatal error: Call to undefined method DOMElement::next_sibling()

Can anybody tell me what’s wrong with my script please?

The error is quite clear: there is no method DOMElement::next_sibling() . Read the documentation for DOMElement and it’s parent class DOMNode . You are thinking of the property DOMNode::nextSibling .

However, nextSibling gets the next node, not the next element. (There is no DOM method or property that gets the next element. You need to keep using nextSibling and checking nodeType until you hit another element.) Your question says you want the next node but I think you may actually want the next element (the empty

To get it immediately:

To get it when you already have a

There’s is not function called next_sibling() in DOM. You should use the property nextSibling defined in DOMNode (http://www.php.net/manual/en/class.domnode.php).

I don’t know php but this xpath gets them:

Ignoring text nodes (hopefully, not tested)
