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")
XXX. DOM Functions
简介
The DOM extension allows you to operate on XML documents through the DOM API with PHP 5.
For PHP 4, use DOM XML.
安装
本扩展模块作为 PHP 内核的一部分，无需安装即可使用。
预定义类
The API of the module follows the » DOM Level 3 standard as closely as possible. Consequently, the API is fully object-oriented. It is a good idea to have the DOM standard available when using this module.
This module defines a number of classes, which are explained in the following tables. Classes with an equivalent in the DOM standard are named DOMxxx.
Extends DOMNode. The DOMAttr
interface represents an attribute in an DOMElement object.
DOMAttr->__construct() - construct a new DOMAttr object
DOMAttr->isId() - Checks if attribute is a defined ID
Extends DOMNode.

In response to lutfi at smartconsultant dot us :
(see my post on
http://fr2.php.net/manual/en/
function.dom-domdocument-getelementsbytagname.php
)
Use this class I wrote:
class XPathableNode extends DOMNode
{
protected $Node;
protected $DOMDocument_from_node;
protected $DOMXpath_for_node;
public function __construct(/* DOMNode */ $node)
{
$this->Node=$node;
$this->DOMDocument_from_node=new
DomDocument();
$domNode=$this->DOMDocument_from_node
->importNode($this->Node, true);
$this->DOMDocument_from_node
->appendChild($domNode);
$this->DomXpath_for_node =
new Domxpath($this->
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.

Basicly there are alot of problems on dynamic namespaces registering and other maybe 'not well' documented parts of DOM.
Here is an article covering some of the problems that our company web developers found while we were developing a template engine for our new framework.

i have some problem parsing recurred xml tree here:
<menu name='parent1' >
<submenu name='file' >
<submenu name='open' >Open file</submenu>
<submenu name='close' >Close file</submenu>
</submenu>
<submenu name='edit' >
<submenu name='cut' >Cut Clipboards</submenu>
<submenu name='copy' >Copy Clipboards</submenu>
<submenu name='paste' >Paste Clipboards</submenu>
</submenu>
</menu>
with getElementsByTagName all submenu is on the same level.
i want it to be structured like tree list, but not change the 'submenu' tag

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;
}

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;
}

I wrote a couple of functions to:
- create a DOMDocument from a file
- parse the namespaces in it
- create a XPath object with all the namespaces registered
- load the schemalocations
- validate the file on the main schema (the one without prefix)
It is useful for me, see if it is also for someone else!!

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;
}

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:

For XSLT:

Most email clients ignore stylesheets in HTML formatted emails. The best way to ensure your HTML is formatted correctly by a broad spectrum of email clients, including webmail implementations as Gmail, is to use inline style attributes. The following function uses DOM to parse an inline stylesheet, and will replace element class and id attributes with inline style attributes, and add inline style attributes for generic tag stylesheet rules. It will remove the stylesheet and any used class and id attributes as these are defunct for most email clients. It is a fairly lightweight function and does not support CSS inheritance, but will work for simple stylesheets e.g.:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>HTML EMAIL</title>
<style type="text/css">
body {
margin: 10px 10px;
font: 8pt arial;
background: #fff;
color: #000;
}
p {
margin: 0 0 10px;
line-height: 1.2em;
text-align: justify;
}
p.centered {
text-align: centre;
}
p#right {
text-align: right;
}
</style>
</head>
<body>
<p>Sample text justified</p>
<p class="centered">Centered text here</p>
<p id="right">Right-aligned text</p>
</body>
</html>
Here's the function:
<?php
function parseStyleSheetfor Email($html)
{
$doc = new DOMDocument;
$doc->loadHTML($html);
// grab inline stylesheet as DOM object
$oStyle = $doc->getElementsByTagName('style')->item(0);
// grab rule identifiers and rules
preg_match_all('/^([-#._a-z0-9]+) ?\{(.*?)\}/ims', $oStyle->nodeValue, $aMatches, PREG_SET_ORDER);
foreach ($aMatches as $aRule) {
$rule_id = $aRule[1];
// clean up rules
$rule = str_replace(array("\r", "\n", ' ', '; '), array('', '', ' ', ';'), $aRule[2]);
$rule = preg_replace(array('/^ /', '/;$/'), '', $rule);
// generic rules
if (!strstr($rule_id, '.') && !strstr($rule_id, '#')) {
$items = $doc->getElementsByTagName($rule_id);
// set style attribute equal to rule from stylesheet
foreach ($items as $item) {
// if there is already inline style append it to end of stylesheet rule
$current_style = $item->getAttribute('style');
if (!empty($current_style)) {
$item->setAttribute('style', $rule . ';' . $current_style);
} else {
$item->setAttribute('style', $rule);
}
}
// classes
} elseif (strstr($rule_id, '.')) {
list($rule_tag, $rule_class) = explode('.', $rule_id);
$items = $doc->getElementsByTagName($rule_tag);
foreach ($items as $item) {
$class = $item->getAttribute('class');
if ($class == $rule_class) {
// if there is already inline style append it to end of stylesheet rule
$current_style = $item->getAttribute('style');
if (!empty($current_style)) {
$item->setAttribute('style', $current_style . ';' . $rule);
} else {
$item->setAttribute('style', $rule);
}
// remove class as it won't be used now
$item->removeAttribute('class');
}
}
// ids
} elseif (strstr($rule_id, '#')) {
list($rule_tag, $id) = explode('#', $rule_id);
$item = $doc->getElementById($id);
$current_style = $item->getAttribute('style');
if (!empty($current_style)) {
$item->setAttribute('style', $current_style . ';' . $rule);
} else {
$item->setAttribute('style', $rule);
}
// remove class as it won't be used now
$item->removeAttribute('id');
}
}
// remove inline stylesheet
$oStyle->parentNode->removeChild($oStyle);
return $doc->saveHTML();
}

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( "" );
}
}
?>

Being an experienced ASP developer I was wondering how to replace textual content of a node (with msxml this is simply acheived by setting the 'text' property of a node). Out of frustration I started to play around with SimpleXml but I could not get it to work in combination with xPath.
I took me a lot of time to find out so I hope this helps others:
function replaceNodeText($objXml, $objNode, $strNewContent){
/*
This function replaces a node's string content with strNewContent
*/
$objNodeListNested = &$objNode->childNodes;
foreach ( $objNodeListNested as $objNodeNested ){
if ($objNodeNested->nodeType == XML_TEXT_NODE)$objNode->removeChild ($objNodeNested);
}
$objNode->appendChild($objXml->createTextNode($strNewContent));
}
$objXml= new DOMDocument();
$objXml->loadXML('<root><node id="1">bla</note></root>');
$objXpath = new domxpath($objXml);
$strXpath="/root/node[@id='1']";
$objNodeList = $objXpath ->query($strXpath);
foreach ($objNodeList as $objNode){
//pass the node by reference
replaceNodeText($objXml, &$objNode, $strImportedValue);
}

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).
