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: <div><p>First text.</p><ul><li><p>First bullet</p></li></ul></div>, you'll get XML_ELEMENT_NODEs that are quite regular. The <div> has children <p> and <ul> and the nodeValue for both <p>s yields the text you expect.



But when your markup is more like <p>This is <b>bold</b> and this is <i>italic</i>.</p>, you realize that the nodeValue for XML_ELEMENT_NODEs is not reliable. In this case, you need to look at the <p>'s child nodes. For this example, the <p> has children: #text, <b>, #text, <i>, #text. 



In this example, the nodeValue of <b> and <i> is the same as their #text children. But you could have markup like: <p>This <b>is bold and <i>bold italic</i></b>, you see?</p>. In this case, you need to look at the children of <b>, which will be #text, <i>, because the nodeValue of <b> 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 <body> 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.

getAttribute() returns an empty string if the requested attribute doesn't exist in the node.

If you have empty $node->textContent and $node->textValue, check if document that is loaded have UTF-8 encoding.

Just discovered that node->nodeValue strips out all the tags

For a reference with more information about the XML DOM node types, see http://www.w3schools.com/dom/dom_nodetype.asp



(When using PHP DOMNode, these constants need to be prefaced with "XML_")

R. Studer 13-Jan-2010 09:03


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.



See: http://www.php.net/manual/en/class.domelement.php

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:



<?php



$node->removeChild($node->firstChild);

$node->appendChild(new DOMText('new text content'));



?>



This example shows what happens:



<?php



$doc = DOMDocument::loadXML('<node>old content</node>');

$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";



?>



The output is:



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:



<?php

$doc = DOMDocument::loadXML('<node>old content</node>');

$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";

?>

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.

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

matt at lamplightdb dot co dot uk 06-Apr-2009 05:39


And apparently also a setAttribute method too:



$node->setAttribute( 'attrName' , 'value' );

jorge dot hebrard at gmail dot com 23-Jan-2009 05:29


Try canonicalization:

<?php

$dom = new DOMDocument;

$dom->loadHTMLFile('http://www.example.com/');

echo $dom->documentElement->C14N();

?>



Or output it to a file, using C14NFile()



Undocumented stuff ;)

brian wildwoodassociates.info 07-Dec-2008 11:27


This class has a getAttribute method.



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



    $url = $ref->getAttribute('href'); 



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