Öntanımlı Sabitler
The PHP 5.0 DOM is very powerful to create and work on valid RSS Feeds. I found a easy to follow step-by-step-tutorial here:
http://xml-rss.de/xml-rss-feed-mit-php.htm
(in german language but the code can be understand in every language i think) maybe it helps someone to understand the DOM-Thing better. But beware it don´t work on PHP 4!
DOM XML (PHP 4) İşlevleri
Kullanımı Önerilmeyen İşlevler
DOM standardına uygun olmayan bir kaç işlev bulunmakta olup artık kullanılmamaları gerekir. Bu işlevler aşağıdaki tabloda listelenmiştir. DomNode_append_child() işlevinin davranışı değişmiştir. Artık bir kardeş değil bir çocuk düğüm eklemektedir. Bu durum uygulamanızın davranışını bozuyorsa, bu işlev yerine bir DOM işlevi olmayan DomNode_append_sibling() işlevini kullanın.
| Eski işlev | Yeni işlev |
|---|---|
| xmldoc() | domxml_open_mem() |
| xmldocfile() | domxml_open_file() |
| domxml_new_xmldoc() | domxml_new_doc() |
| domxml_dump_mem() | DomDocument::dump_mem() |
| domxml_dump_mem_file() | DomDocument::dump_file() |
| DomDocument_dump_mem_file() | DomDocument::dump_file() |
| DomDocument_add_root() | DomDocument::create_element() işlevinden sonra DomNode::append_child() |
| DomDocument_dtd() | DomDocument::doctype() |
| DomDocument_root() | DomDocument::document_element() |
| DomDocument_children() | DomNode::child_nodes() |
| DomDocument_imported_node() | Karşılığı yoktur. |
| DomNode_add_child() | Örneğin, DomDocument::create_element() ile yeni bir düğüm oluşturup çocuk düğümü DomNode::append_child() ile ekleyin. |
| DomNode_children() | DomNode::child_nodes() |
| DomNode_parent() | DomNode::parent_node() |
| DomNode_new_child() | Örneğin, DomDocument::create_element() ile yeni bir düğüm oluşturup çocuk düğümü DomNode::append_child() ile ekleyin. |
| DomNode_set_content() | Örneğin, DomDocument::create_text_node() ile yeni bir düğüm oluşturup çocuk düğümü DomNode::append_child() ile ekleyin. |
| DomNode_get_content() | İçerik bir metin düğümü olup içeriğe DomNode::child_nodes() ile erişilebilir. |
| DomNode_set_content() | İçerik bir metin düğümü olup DomNode::child_nodes() işlevi ile eklenebilir. |
Sınıflar
Modül arayüzü 2. seviye DOM standardına mümkün olduğunca uygun olup arayüz tamamen nesne yönelimlidir. Bu modülü kullanabilmek için DOM standardını bilmeniz iyi olacaktır. Arayüz nesne yönelimli olsa da ilk değiştirgesinde nesneyi aktarmak suretiyle kullanılabilen nesne yönelimli olmayan bazı işlevler de vardır. Bu işlevler esas olarak, eklentinin eski sürümlerine uyumluluk için vardır ve yeni betiklerde kullanılmamalıdır.
Bu arayüz DOM arayüzünden iki bakımdan farklıdır. İlki, tüm sınıf özellikleri aynı isimde birer işlev olarak gerçeklenmiştir. İkinci fark ise, işlev isimlerinin PHP isimlendirme kurallarına göre verilmiş olmasıdır. Yani, örneğin, lastChild() DOM işlevi last_child() adıyla gerçeklenmiştir.
Bu modülde tanımlanan sınıflar ve yöntemleri aşağıdaki tablolarda listelenmiştir. DOM standardına eşdeğer sınıflar DOMxxx biçeminde isimlendirilmiştir.

Hi at All,
if you use xpath_eval() you get a xpathobject with a type-member-variable, which tells you about the type of the found content. Here are the values and the corresponding types:
1 = XPATH_NODESET (integer)
2 = XPATH_BOOLEAN (integer)
3 = XPATH_NUMBER (integer)
4 = XPATH_STRING (integer)
I think, but don't know, that the rest of the constants are:
0 = XPATH_UNDEFINED (integer)
5 = XPATH_POINT (integer)
6 = XPATH_RANGE (integer)
7 = XPATH_LOCATIONSET (integer)
I hope i could help some people.
Greetz,

Referenced array functions drive me crazy for one reason or another (personal issue I guess). So for any others like me, here's my modification (thanks to the original posters below for the base to work on!)
I haven't tested this on much more than simple XML files, so there's probably a few ways to break this - I'm also thinking this could probably be rewritten to be more efficient also, but it's working quite well for me thus far.
<?php
function xml2array($domnode)
{
$nodearray = array();
$domnode = $domnode->firstChild;
while (!is_null($domnode))
{
$currentnode = $domnode->nodeName;
switch ($domnode->nodeType)
{
case XML_TEXT_NODE:
if(!(trim($domnode->nodeValue) == "")) $nodearray['cdata'] = $domnode->nodeValue;
break;
case XML_ELEMENT_NODE:
if ($domnode->hasAttributes() )
{
$elementarray = array();
$attributes = $domnode->attributes;
foreach ($attributes as $index => $domobj)
{
$elementarray[$domobj->name] = $domobj->value;
}
}
break;
}
if ( $domnode->hasChildNodes() )
{
$nodearray[$currentnode][] = xml2array($domnode);
if (isset($elementarray))
{
$currnodeindex = count($nodearray[$currentnode]) - 1;
$nodearray[$currentnode][$currnodeindex]['@'] = $elementarray;
}
} else {
if (isset($elementarray) && $domnode->nodeType != XML_TEXT_NODE)
{
$nodearray[$currentnode]['@'] = $elementarray;
}
}
$domnode = $domnode->nextSibling;
}
return $nodearray;
}

My short way of parsing an XML document, for example displaying the document in a structured form:
<?php
$indent = "";
$file = "semi.xml";
$showfile = file_get_contents("c:/Program Files/Apache Group/apache/htdocs/phpxml" . "/" . $file); // whatever path
// maybe the whole path is not important, look it up in other posts
$newstring=utf8_encode($showfile); // it's important!
if(!$domDocument = domxml_open_mem($newstring)) {
echo "Couldn't load xml...";
exit;
}
$rootDomNode = $domDocument->document_element();
print "<pre>";
printElements($rootDomNode);
print "</pre>";
function printElements($domNode)
{
if($domNode)
{
global $indent;
if($domNode->node_type() == XML_ELEMENT_NODE)
{
print "<br />".$indent."<".$domNode->node_name();
if($domNode->has_attributes())
{
$attributes = $domNode->attributes();
foreach($attributes as $domAttribute)
{
print " $domAttribute->name=\"$domAttribute->value\"";
}
}
print ">";
if($domNode->has_child_nodes())
{
$indent.=" ";
$nextNode = $domNode->first_child();
printElements($nextNode);
$indent= substr($indent, 0, strlen($indent)-2);
print "<br />".$indent."<"."/".$domNode->node_name().">";
}
else
{
print "$domNode->node_value()</".$domNode->node_name().">";
}
}
$nextNode = $domNode->next_sibling();
printElements($nextNode);
}
}
?>

Re: websiterepairguys... Close but no cigar ;-)
As written it will not work if the repeated tags are somewhere other than the first node, i.e. the following will not work:
<nodes>
<node>onething</node>
<node>something</node>
<node>something</node>
</nodes>
You must store the new node name when you get a new sibling that doesn't match the previous and then it will work OK. Amended code:
function dom_to_array($domnode, &$array) {
$parent=$domnode;
$domnode = $domnode->firstChild;
$myname=$domnode->nodeName;
$x=1;
while (!is_null($domnode)) {
switch ($domnode->nodeType) {
case XML_ELEMENT_NODE: {
if ( !$domnode->hasChildNodes()) {
$array[$domnode->nodeName]='';
} else if ( $domnode->hasChildNodes() && $domnode->firstChild->nodeType==XML_TEXT_NODE) {
$array[$domnode->nodeName]=$domnode->firstChild->nodeValue;
} else if ( $domnode->hasChildNodes() ) {
$array_ptr = & $array[$domnode->nodeName];
dom_to_array($domnode, $array_ptr);
}
break;
}
}
$domnode = $domnode->nextSibling;
if($domnode->nodeName == $myname)
{
$domnode->nodeName.=($x++);
} else {
$myname = $domnode->nodeName;
}
}
}

I tried using the dom_to_simple_array that the user jas posted above, but it didnt work very well.
The problems were it didnt handle sibling nodes with the same name, such as:
<nodes>
<node>something</node>
<node>something</node>
</nodes>
Also, when it built child arrays from child nodes, it always interjected an wrapping array around the child, which isnt necessary. Here is the patched code:
function dom_to_array($domnode, &$array) {
$parent=$domnode;
$domnode = $domnode->firstChild;
$myname=$domnode->nodeName;
$x=1;
while (!is_null($domnode)) {
switch ($domnode->nodeType) {
case XML_ELEMENT_NODE: {
if ( !$domnode->hasChildNodes()) {
$array[$domnode->nodeName]='';
} else if ( $domnode->hasChildNodes() && $domnode->firstChild->nodeType==XML_TEXT_NODE) {
$array[$domnode->nodeName]=$domnode->firstChild->nodeValue;
} else if ( $domnode->hasChildNodes() ) {
$array_ptr = & $array[$domnode->nodeName];
dom_to_array($domnode, $array_ptr);
break;
}
}
}
$domnode = $domnode->nextSibling;
if($domnode->nodeName==$myname)
{
$domnode->nodeName.=($x++);
}
}
}
snippet of array produced by this:
[admin] => Array
(
[menu] => Array
(
[title] => Page Manager
[view] => list
)
[files] => Array
(
[filename] => modules/testmodule/testmodule.php

If you want to subclass the domxml-classes, you have to use PHP5. It doesn't work with PHP4, and never will.

If you are using apache, instead of copying files around (iconv.dll for instance) you can use this in your httpd.conf for apache:
LoadFile "d:/php/dlls/iconv.dll"
I placed this line before
LoadModule php4_module "d:/php/sapi/php4apache2.dll"
and it worked, no copying of files or anything therefore helps when updating php, don't have to mess around searching for files and other stuff.

I recently developed a script for parsing DHL XML transaction responses - finding it a pain in the rear to actually parse the XML and set my variables - it actually wasn't that hard once I figured it out - and it goes something like this...
<?php
// Use with a class containing functions set_attributes() and
// set_data(). Use the following to set variables from the
// resulting xml. $node is a dom xml object - in the first call
// to loop, $node would be equal to the root document
// element.
function loop($node) {
// set attribute tags here
if ($node->has_attributes()) {
$this->set_attributes($node);
} // end if node has attributes
if ($node->has_child_nodes()) {
$this->loop($node->first_child());
} // end if node has child
else {
$this->set_data($node);
} // end if node has no child
// get next sibling
$node = $node->next_sibling();
if ($node) {
$this->loop($node);
} // end if node
} // end function loop
?>
The code goes from the root element, if the element has attributes - it sets attribute variables. Second, it recursively proceeds to the lowest level element (no more children). Once that level has been reached, data variables are set. The next step goes to the next sibling of the element, if it exists. If the next sibling does not exists, the function is ended and the current element is returned to the parent element. The parent element is then checked for siblings. This process continues (as is with recursion) until the parent element is back at the root element, which is the end of the document.

You can always use a sax parser (expat) which saves on memory storage (there is none as sax is event driven) and use this neat code to produce an array structure of you xml file :

i needed to have an easy way to create a multi-dimensional but EXTREMELY SIMPLE php array out of some XML text i'm receiving. NOT an object. just an ARRAY.
i found that as simple a request as this seemed to be, the new (php5) DOM functions do not provide this functionality.
even the SimpleXML functions are object-oriented, which doesn't work for some of my purposes (sending to a Smarty template variable for looping through, etc.) -- returning attributes as SimpleXMLElement objects instead of strings, etc.. i just wanted an ARRAY containing the data as STRINGS.
eli (http://www.hoktar.com) had submitted such code earlier, based on domxml/php4 calls. his function was called "domxml_xmlarray".
but when php5 came out, eli's comments at the bottom of the PHP site got erased. (fortunately, i had already saved his code.) no doubt, mine will too w/next version..
furthermore, as far as i can tell, no one has taken the cue to add something like eli's domxml_xmlarray function directly into the DOMDocument object (but it would be nice).
so i translated eli's code, now using the dom calls (instead of the older domxml calls), and renamed the function to "dom_to_simple_array()".
below is a script containing the function itself as well as an example of its use. just copy it to your server somewhere and execute it and it should work right off the bat if you are using php5.
thanks.

PHP4/DOMXML code is not compatible with the new PHP5/dom extension. While the conversion is quite strait forward, it can take a long time if domxml has been broadly used. Moreover, it can be interesting to have old PHP4 scripts ready for PHP5 as soon as possible even if the server is still running PHP4. Since I have that kind of problem, if have written a small library to include in PHP4 scripts to enable them to be run on PHP5. http://alexandre.alapetite.net/doc-alex/domxml-php4-php5/
It does not cover all the domxml functionality, but most of the main functions and can easily be extended. Tested with PHP4.3.7 and PHP5.0.0RC3 but I will try to keep it updated. I hope it can help.

When installing PHP --with-dom and --with-dom-xslt on a Red Hat 9.0 remember to install the following packages:
libxml
libxml2
libxml2-devel
libxslt
libxslt-devel
Then you will be spared error messages when trying to configure.

If you need to parse XML on an older version of PHP (e.g. 4.0) or if you can't get the expat extension enabled on your server, you might want to check out the Saxy and DOMIT! xml parsers from Engage Interactive. They're opensource and pure php, so no extensions or changes to your server are required. I've been using them for over a month on some projects with no problems whatsoever!
Check em out at:
DOMIT!, a DOM based xml parser, uses Saxy (included)
http://www.engageinteractive.com/redir.php?resource=3&target=domit
or
Saxy, a sax based xml parser

This recursive function will iterate over a DOM object and display it as a nicely formatted XML structure. I used intuitive variable names to help learn more about the DOM functions and their return values.
<<?php
function PrintDomTree($DomNode)
{
if ($ChildDomNode = $DomNode->first_child()) {
static $depth = 0;
$whitespace = "\n<br>".str_repeat(" ", ($depth * 2));
while ($ChildDomNode) {
if ($ChildDomNode->node_type() == XML_TEXT_NODE) {
echo trim($ChildDomNode->node_value());
} elseif ($ChildDomNode->node_type() == XML_ELEMENT_NODE) {
$HasTag = 1;
echo $whitespace;
echo "<", $ChildDomNode->node_name();
if ($ChildDomNode->has_attributes()) {
$Array = $ChildDomNode->attributes();
foreach ($Array AS $DomAttribute) {
echo " ", $DomAttribute->name(), "=\"", $DomAttribute->value(), "\"";
}
}
echo ">";
if ($ChildDomNode->has_child_nodes()) {
$depth++;
if (PrintDomTree($ChildDomNode)) {
echo $whitespace;
}
$depth--;
}
echo "</", $ChildDomNode->node_name(), ">";
}
$ChildDomNode = $ChildDomNode->next_sibling();
}
return $HasTag;
}
}
?>

If you're having trouble understanding how the the DOM XML extension fits together you may find the UML diagram here helps: http://www.phppatterns.com/index.php/article/articleview/38

When parsing "iso-8859-1" encoded XML files, use "utf8_decode" to recover node contents (libxml uses "UTF-8" internal encoding, so conversion needed).
--- BEGIN: mydata.xml ---
<?xml version="1.0" encoding="iso-8859-1"?>
...
--- END: mydata.xml---
--- BEGIN: myparser.php ---
<?php
...
$domxml = domxml_open_file("mydata.xml"));
...
$content = utf8_decode(trim($node->content));
echo $content;
...
?>
--- END: myparser.php
