If you need simple interface to DOM check out phpQuery - jQuery port to PHP:
http://code.google.com/p/phpquery/

It uses CSS selectors to fetch nodes.
Here's example how it works:
<?php
// just one file to include
require('phpQuery/phpQuery.php');

$html = '
<div>
    mydiv
    <ul>
        <li>1</li>
        <li>2</li>
        <li>3</li>
    </ul>
</div>'
;

// intialize new DOM from markup
phpQuery::newDocument($markup)
    ->
find('ul > li')
        ->
addClass('my-new-class')
        ->
filter(':last')
            ->
addClass('last-li');

// query all unordered lists in last used DOM
pq('ul')->insertAfter('div');

// iterate all LIs from last used DOM
foreach(pq('li') as $li) {
   
// iteration returns plain DOM nodes, not phpQuery objects
   
pq($li)->addClass('my-second-new-class');
}

// same as pq('anything')->htmlOuter()
// but on document root (returns doctype etc)
print phpQuery::getDocument();
?>

It uses DOM extension and XPath so it works only in PHP5.

As of PHP 5.1, libxml options may be set using constants rather than the use of proprietary DomDocument properties.

DomDocument->resolveExternals is equivilant to setting
LIBXML_DTDLOAD
LIBXML_DTDATTR

DomDocument->validateOnParse is equivilant to setting
LIBXML_DTDLOAD
LIBXML_DTDVALID

PHP 5.1 users are encouraged to use the new constants.

Example:

DomDocument->load($file, LIBXML_DTDLOAD|LIBXML_DTDATTR);

DomDocument->load($file, LIBXML_DTDLOAD|LIBXML_DTDVALID);

I needed a function that quickly converts an xml with key/value pairs to an array.

for example:
<?xml version="1.0" encoding="UTF-8"?>
<test>
    <key id="Array key #1" value="Value #1"/>
    <key id="Array key #2" value="Value #2"/>
    <key id="Dupe" value="Duplicate keys"/>
    <key id="Dupe" value="create numeric arrays"/>
    <key id="And another key">
        <![CDATA[
            Multiline
            data
            works
            just
            as
            well.
        ]]>
    </key>
    <nested>
        <key id="Nested key" value="Nested data works as well, but it still results in a 1 dimensional array."/>
    </nested>
</test>

Results in the following array:
array(5) {
  ["Array key #1"]=>
  string(8) "Value #1"
  ["Array key #2"]=>
  string(8) "Value #2"
  ["Dupe"]=>
  array(2) {
    [0]=>
    string(14) "Duplicate keys"
    [1]=>
    string(21) "create numeric arrays"
  }
  ["And another key"]=>
  string(49) "Multiline
            data
            works
            just
            as
            well."
  ["Nested key"]=>
  string(73) "Nested data works as well, but it still results in a 1 dimensional array."
}

Here's the code:
<?php
   
function xml2array($xml) {
       
$domDocument = new DOMDocument;
       
$domDocument->loadXML($xml);
       
$domXPath = new DOMXPath($domDocument);
       
$array = array();
        foreach (
$domXPath->query('//key') as $keyDOM) {
           
$id = $keyDOM->getAttribute('id');
           
$value = $keyDOM->hasAttribute('value') ? $keyDOM->getAttribute('value') : trim($keyDOM->textContent);
            if (
array_key_exists($id, $array)) {
                if (
is_array($array[$id])) {
                   
$array[$id][] = $value;
                } else {
                   
$array[$id] = array($array[$id]);
                   
$array[$id][] = $value;
                }
            } else {
               
$array[$id] = $value;
            }
        }
        return
$array;
    }

If you are using not object-oriented functions and it takes too much time to change them all (or you'll be replacing them later) then as a temporary decision can be used this modules:

For DOM XML:
http://alexandre.alapetite.net/doc-alex/domxml-php4-php5/

For XSLT:

A function among several others to parse a google results page, I wrote this some time ago - google has probably changed their site since then, but I thought this might be helpful to someone.

I'm moving servers, but I will probably throw this up on my blog when I get it back up.

<?php

function googleResult($listItem) {
   
// given a LIST ITEM element, this will validate, and return an array for that LI entry as an inline result from google.
    /*
     * <li class='g w0'>
     *   <h3 class='r'>
     *     <a href='the URL' class='l'>
     *       Description <em>description</em>
     *     </a>
     *   </h3>
     * </li>
     *
       UPDATE:
       This function will now look for any subcontainer that has an href, it doesn't have to be an H3
       this will make it work with a few more formatted search results.
     */

   
$listItem = $listItem->childNodes;
       
// Yes I don't use instanceof - I guess you'll have to deal.
   
foreach($listItem as $element) {
        if(
is_object($element) && get_class($element) == 'DOMElement' && $element->hasChildNodes()) {
           
$hrefContainer = $element->childNodes;
            foreach(
$hrefContainer as $element2) {
                if(
is_object($element2) && get_class($element2) == 'DOMElement' && $element2->nodeName == 'a' && $element2->hasAttribute('href')) {
                   
$anchor = $element2;
                    unset(

After searching how to extend the DOMDocument and DOMElement I found a way in the bug: http://bugs.php.net/bug.php?id=35104. The following code shows how:

<?php
class extDOMDocument extends DOMDocument {
public function
createElement($name, $value=null) {
 
$orphan = new extDOMElement($name, $value); // new  sub-class object
 
$docFragment = $this->createDocumentFragment(); // lightweight container maintains "ownerDocument"
 
$docFragment->appendChild($orphan); // attach
 
$ret = $docFragment->removeChild($orphan); // remove
 
return $ret; // ownerDocument set; won't be destroyed on  method exit
}
// .. more class definition
}

class
extDOMElement extends DOMElement {
function
__construct($name, $value='', $namespaceURI=null) {
 
parent::__construct($name, $value, $namespaceURI);
}
 
//  ... more class definition here
}

$doc = new extDOMDocument('test');
$el = $doc->createElement('tagname');
$el->setAttribute("attr", "val");
$doc->appendChild($el);

// append discards the DOMDocumentFragment and just adds its child nodes, but ownerDocument is maintained.
echo get_class($el)."<br/>";
echo
get_class($doc->documentElement)."<br/>";
echo
"<xmp>".$doc->saveXML()."</xmp>";
?>

The following can take a XML_TEXT_NODE node and return the contents in an array. Yanick's contribution rocks - but
it overwrote with duplicates only keeping the last line
in the returned array. All the other functions i tested from various sources failed to handle text nodes correctly. Hope this helps someone. It is adapted from code on this site.

function myTextNode($n, &$a)
{
static $depth = 0;
static $sz = '';

if ($cn = $n->firstChild)
{
  while ($cn)
  {
   if ($cn->nodeType == XML_TEXT_NODE)
   {
    $sz .= $cn->nodeValue;
   }
   elseif ($cn->nodeType == XML_ELEMENT_NODE)
   {
    $b = 1;
    if ($cn->hasChildNodes())
    {
     $depth++;
     if ($this->myHeadings($cn, $a))
     {
      if ($sz){
       array_push($a, $sz);
       $sz = '';
      }
     }
     $depth--;
    }
   }
   $cn = $cn->nextSibling;
  }
  return $b;
}
}

so you could use:  

$nodes = $dom->getElementsByTagName("td");
if($nodes){
foreach ($nodes as $node){
  $a = Array();
  myTextNode($node, $a);
}
}

I found the xml2array function below very useful, but there seems to be a bug in it. The $item variable was never getting set. I've expanded this out to be a bit more readable, and the corrected code is :

function xmlToArray($n)
{
    $return=array();

    foreach($n->childNodes as $nc){
        if( $nc->hasChildNodes() ){
            if( $n->firstChild->nodeName== $n->lastChild->nodeName&&$n->childNodes->length>1){
                $item = $n->firstChild;
                $return[$nc->nodeName][]=$this->xmlToArray($item);
            }
            else{
                 $return[$nc->nodeName]=$this->xmlToArray($nc);
            }
       }
       else{
           $return=$nc->nodeValue;
       }
    }
    return $return;

The project I'm currently working on uses XPaths to dynamically navigate through chunks of an XML file.  I couldn't find any PHP code on the net that would build the XPath to a node for me, so I wrote my own function.  Turns out it wasn't as hard as I thought it might be (yay recursion), though it does entail using some PHP shenanigans... 

Hopefully it'll save someone else the trouble of reinventing this wheel.

<?php
   
function getNodeXPath( $node ) {
       
// REMEMBER THAT XPATHS USE BASE-1 INSTEAD OF BASE-0!!!
       
        // Get the index for the current node by looping through the siblings.
       
$parentNode = $node->parentNode;
        if(
$parentNode != null ) {
           
$nodeIndex = 0;
            do {
               
$testNode = $parentNode->childNodes->item( $nodeIndex );
               
$nodeName = $testNode->nodeName;
               
$nodeIndex++;
               
               
// PHP trickery!  Here we create a counter based on the node
                //  name of the test node to use in the XPath.
               
if( !isset( $$nodeName ) ) $$nodeName = 1;
                else $
$nodeName++;
               
               
// Failsafe return value.
               
if( $nodeIndex > $parentNode->childNodes->length ) return( "/" );
            } while( !
$node->isSameNode( $testNode ) );
           
           
// Recursively get the XPath for the parent.
           
return( getNodeXPath( $parentNode ) . "/{$node->nodeName}[{$$nodeName}]" );
        } else {
           
// Hit the root node!  Note that the slash is added when
            //  building the XPath, so we return just an empty string.
           
return( "" );
        }
    }
?>

Note that these DOM functions expect (and presumably return) all their data in UTF-8 character encoding, regardless of what PHP's current encoding is. This means that text nodes, attribute values etc, should be in utf8.

This applies even if you're generating an XML document which is not ultimately in utf8.

This module is not included by default either in the CentOS 4 "centosplus" repository. For those using PHP5 on CentOS 4, a simple "yum --enablerepo=centosplus install php-xml" will do the trick (this will install both the XML and DOM modules).

When dealing with validation or loading, the output errors can be quite annoying.

PHP 5.1 introduces libxml_get_errors().

The Yanik's dom2array() function (added on 14-Mar-2007 08:40) does not handle multiple nodes with the same name, i.e.:

<foo>
  <name>aa</name>
  <name>bb</name>
</foo>

It will overwrite former and your array will contain just the last one ("bb")

                                         DOMDocument_from_node);
    }

    public function convertHTML()
    {    return $this->DOMDocument_from_node
                                                             ->saveHTML();
    }

    public /*DomNodeList*/ function applyXpath($xpath)
    {    return $this->DomXpath_for_node
                                                       ->query($xpath);
    }
}

(sorry for the display... What a terrible hinderance on the
part of php.net !)

Then :
Make a new XPathableNode out of your parent node.
You may then retrieve a DOMNodeList from it by applying a
xpath (thus being able to specify the depth  and name of
elements you want).

Has got me around some (of the many) DOM awkwardnesses a few times.

I hate DOM model !
so I wrote dom2array simple function (simple for use):

function dom2array($node) {
  $res = array();
  print $node->nodeType.'<br/>';
  if($node->nodeType == XML_TEXT_NODE){
      $res = $node->nodeValue;
  }
  else{
      if($node->hasAttributes()){
          $attributes = $node->attributes;
          if(!is_null($attributes)){
              $res['@attributes'] = array();
              foreach ($attributes as $index=>$attr) {
                  $res['@attributes'][$attr->name] = $attr->value;
              }
          }
      }
      if($node->hasChildNodes()){
          $children = $node->childNodes;
          for($i=0;$i<$children->length;$i++){
              $child = $children->item($i);
              $res[$child->nodeName] = dom2array($child);
          }
      }
  }
  return $res;
}

If  you want to print the DOM XML file content, you can use the next code:

$doc = new DOMDocument();
$doc->load($xmlFileName);
echo "<br>" . $doc->documentURI;
$x = $doc->documentElement;
getNodeContent($x->childNodes, 0);

function getNodeContent($nodes, $level){
    foreach ($nodes AS $item) {
    //  print "<br><br>TIPO: " . $item->nodeType ;
      printValues($item, $level);
      if ($item->nodeType == 1) { //DOMElement
          foreach ($item->attributes AS $itemAtt) {
              printValues($itemAtt, $level+3);
          }
          if($item->childNodes || $item->childNodes->lenth > 0) {
              getNodeContent($item->childNodes, $level+5);
          }
      }
    }
}

function printValues($item, $level){
    if ($item->nodeType == 1) { //DOMElement
        printLevel($level);
        print $item->nodeName . " = " . $item->nodeValue;
    }
    if ($item->nodeType == 2) { //DOMAttr
        printLevel($level);
        print $item->name . " = " . $item->value ;
    }
    if ($item->nodeType == 3) { //DOMText
      if ($item->isWhitespaceInElementContent() == false){
        printLevel($level);
        print $item->wholeText ;
      }
    }
}

function printLevel($level)
{
    print "<br>";
    if ($level == 0) {
        print "<br>";
    }
    for($i=0; $i < $level; $i++) {
        print "-";
    }
}

I wrote a framework to implement the StyleSheet interfaces as specified on the W3C website.  The code is written in PHP, and is NOT a complete implementation.  Use it how ya like.  I was planning on adding the CSSStyleSheet interfaces as well.  Feel free to ask.

<?
   
class StyleSheetList {
        public
length;
        private
self;
       
        function
__construct ( ) {
           
$this->self = array();
        }
       
        function
__get($property, $&ret) {
            if(
$property == 'length')
               
$ret = count($this->self);
            return
true;
        }
       
        function
__set($property, $val) {
            if(
$property == 'length')
                return
true;
        }
       
        function
item( $index ) {
            return
$this->self[$index];
        }
    }
   
    class
MediaList extends StyleSheetList {
       
        function
appendMedium ( $newMedium ) {
           
array_push($this->self, $newMedium);
        }
       
        function
deleteMedium ( $oldMedium ) {
            foreach(
$this->self as $item) {
                if(
$item == $oldMedium ) {
                   
$item = $this->self[ $this->length-1 ];
                   
array_pop($this->self);
                    break;
                }
            }
        }
    }
   
    class
DocumentStyle {
        public
styleSheets;
       
        function
__construct ( ) {
           
$this->styleSheets = new StyleSheetList();
        }
       
        function
__set($property, $val) {
            if(
$property == 'styleSheets')
                return
true;
        }
    }
   
    class
LinkStyle {
        public

        function

$this->sheet = new StyleSheet();
        }

In response to "simlee at indiana dot edu",
- First of all thanks for sharing your funciton.
- It didn't work for me so i rewrite it from scratch using different method.

Here is the new version, hope it helps someone :

<?php
/**
* result sample : /html[1]/body[1]/span[1]/fieldset[1]/div[1]
* @return string
*/
function getNodeXPath( $node ) {   
   
$result='';
    while (
$parentNode = $node->parentNode) {
       
$nodeIndex=-1;
       
$nodeTagIndex=0;
        do {
           
$nodeIndex++;
           
$testNode = $parentNode->childNodes->item( $nodeIndex );
               
            if (
$testNode->nodeName==$node->nodeName and $testNode->parentNode->isSameNode($node->parentNode) and $testNode->childNodes->length>0) {
               
//echo "{$testNode->parentNode->nodeName}-{$testNode->nodeName}-{}<br/>";
               
$nodeTagIndex++;
            }
               
        } while (!
$node->isSameNode($testNode));

       
$result="/{$node->nodeName}[{$nodeTagIndex}]".$result;
       
$node=$parentNode;
    };
    return
$result;
}
?>

innerHTML in PHP DOM

<?php
function DOMinnerHTML($element)
{
   
$innerHTML = "";
   
$children = $element->childNodes;
    foreach (
$children as $child)
    {
       
$tmp_dom = new DOMDocument();
       
$tmp_dom->appendChild($tmp_dom->importNode($child, true));
       
$innerHTML.=trim($tmp_dom->saveHTML());
    }
    return
$innerHTML;
}
?>

Example:

<?php
$dom
= new DOMDocument();
$dom->load($html_string);
$dom->preserveWhiteSpace = false;

$domTable = $dom->getElementsByTagName("table");

foreach (
$domTable as $tables)
{
    echo
DOMinnerHTML($tables);
}
?>

When I tried to parse my XHTML Strict files with DOM extension, it couldn't understand xhtml entities (like &copy;). I found post about it here (14-Jul-2005 09:05) which adviced to add resolveExternals = true, but it was very slow. There was some small note about xml catalogs but without any glue. Here it is:

XML catalogs is something like cache. Download all needed dtd's to /etc/xml, edit file /etc/xml/catalog and add this line: <public publicId="-//W3C//DTD XHTML 1.0 Strict//EN" uri="file:///etc/xml/xhtml1-strict.dtd" />

Thats all. Thanks to http://www.whump.com/moreLikeThis/link/03815

This particular W3C page provides invaluable documentation for the DOM classes implemented in php5 (via libxml2). It fills in plenty of php.net's gaps:

http://www.w3.org/TR/DOM-Level-2-Core/core.html

Some key examples:
* concise summary of the class heirachy (1.1.1)
* clarification that DOM level 2 doesn't allow for population of internal DTDs
* explanation of DOMNode->normalize()
* explanation of the DOMImplementation class

The interfaces are described in OMG's Interface Definition Language

Here is a fast innerHTML function that returns the result without iterating over child nodes.

<?php
function innerHTML($el) {
 
$doc = new DOMDocument();
 
$doc->appendChild($doc->importNode($el, TRUE));
 
$html = trim($doc->saveHTML());
 
$tag = $el->nodeName;
  return
preg_replace('@^<' . $tag . '[^>]*>|</' . $tag . '>$@', '', $html);
}
?>

Example
<?php
$doc
= new DOMDocument();
// A corrupt HTML string
$doc->loadHTML('<HTML><A HREF="ss">asd</A>');
$body = $doc->getElementsByTagName('body')->item(0);
print
htmlspecialchars(innerHTML($body));
// Prints <a href="ss">asd</a>
?>

I had the hardest time updating a complex XML document. Here's a quick example on how to do it.

<?php

// Load the XML from a file.
$xml = "a2062.xml"; // This is an XFDL form previously unencoded and ungzipped.
$dom = new DOMDocument();
$dom->preserveWhiteSpace = false;
$dom->Load($xml);

// Create an XPath query.
// Note: you must define the namespace if the XML document has defined namespaces.
$xpath = new DOMXPath($dom);
$xpath->registerNamespace('xfdl', "http://www.PureEdge.com/XFDL/6.5");

// Locate the value for the first Item Description field.
$query = "//xfdl:page/xfdl:field[@sid='ITEMDESA']/xfdl:value";
$nodeList = $xpath->query($query);

$nodeList->item(0)->nodeValue = "This is the text in the value node of the first Item Description field inside the DA 2062 PureEdge form.";

$dom->save($xml);

?>

I hope this helps someone.

You can get the "innerHTML" by nodeValue so

<?php
    $doc
= new DOMDocument( );
   
$ele = $doc->createElement( 'p', 'Sensei Ninja' );
    print
$ele->nodeValue;
?>

You can even set it if you want

<?php
    $doc
= new DOMDocument( );
   
$ele = $doc->createElement( 'p' );
   
$ele->nodeValue = 'Sensei Ninja';
   
$doc->appendChild( $ele );
    print
$doc->saveHTML( );
?>

when you got variable nodes at start you array fails and looses nodes  beneath.
solution that counts occurance though eats up performance:

function xmlToArray($n)
{
    $xml_array = array();
    $occurance = array();

     foreach($n->childNodes as $nc)
     {
         $occurance[$nc->nodeName]++;
     }
    
    foreach($n->childNodes as $nc){
        if( $nc->hasChildNodes() )
        {
            if($occurance[$nc->nodeName] > 1)
            {
                $xml_array[$nc->nodeName][] = xmlToArray($nc);
            }
            else
            {
                $xml_array[$nc->nodeName] = xmlToArray($nc);
            }
        }
        else
        {
            return utf8_decode($nc->nodeValue);
        }
    }
    return $xml_array;
}

[Editor's Note: If you're using entities, then you have no choice. XML Catalogs can speed DTD resolution.]

Never use

$dom->resolveExternals=true;

when parsing XHTML document that has the DOCTYPE declaration with DTD URL specified in it.

Otherwise parsing the XHTML with DOCTYPE like this one:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
