XXVIII. DOM XML Functions

���

The DOM XML extension has been overhauled in PHP 4.3.0 to better comply with the DOM standard. The extension still contains many old functions, but they should no longer be used. In particular, functions that are not object-oriented should be avoided.

The extension allows you to operate on an XML document with the DOM API. It also provides a function domxml_xmltree() to turn the complete XML document into a tree of PHP objects. Currently, this tree should be considered read-only - you can modify it, but this would not make any sense since DomDocument_dump_mem() cannot be applied to it. Therefore, if you want to read an XML file and write a modified version, use DomDocument_create_element(), DomDocument_create_text_node(), set_attribute(), etc. and finally the DomDocument_dump_mem() function.

注: This extension has been moved to the repository and is no longer bundled with PHP as of PHP 5.0.0.

注: This extension is no longer marked experimental. It will, however, never be released with PHP 5, and will only be distributed with PHP 4. If you need DOM XML support with PHP 5 you can use the DOM extension. This domxml extension is not compatible with the DOM extension.

����

This extension makes use of the . Download and install this library. You will need at least libxml-2.4.14. To use DOM XSLT features you can use the and EXSLT enhancements from . Download and install these libraries if you plan to use (enhanced) XSLT features. You will need at least libxslt-1.0.18.

�װ

This extension is not bundled with PHP. Additional information such as new releases, downloads, source files, maintainer information, and a CHANGELOG, can be located here: .

In PHP 4 this PECL extensions source can be found in the ext/ directory within the PHP source or at the PECL link above. This extension is only available if PHP was configured with --with-dom[=DIR]. Add --with-dom-xslt[=DIR] to include DOM XSLT support. DIR is the libxslt install directory. Add --with-dom-exslt[=DIR] to include DOM EXSLT support, where DIR is the libexslt install directory.

Windows users will enable php_domxml.dll inside of php.ini in order to use these functions. In PHP 4 this DLL resides in the extensions/ directory within the PHP Windows binaries download. You may download this PECL extension DLL from the PHP Downloads page or at . Also, there is one additional DLL that must be made available to your system's PATH in order for this extension to work. In PHP 4 this is in the dlls/ directory. It's name: For PHP <= 4.2.0, it's libxml2.dll. For PHP >= 4.3.0, it's iconv.dll. And as of PHP 5.0.0, iconv is compiled into your Windows PHP binaries by default so no extra DLL is needed.

Deprecated functions

There are quite a few functions that do not fit into the DOM standard and should no longer be used. These functions are listed in the following table. The function DomNode_append_child() has changed its behaviour. It now adds a child and not a sibling. If this breaks your application, use the non-DOM function DomNode_append_sibling().

Classes

The API of the module follows the DOM Level 2 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. Though the API is object-oriented, there are many functions which can be called in a non-object-oriented way by passing the object to operate on as the first argument. These functions are mainly to retain compatibility to older versions of the extension, and should not be used when creating new scripts.

This API differs from the official DOM API in two ways. First, all class attributes are implemented as functions with the same name. Secondly, the function names follow the PHP naming convention. This means that a DOM function lastChild() will be written as last_child().

This module defines a number of classes, which are listed - including their method - in the following tables. Classes with an equivalent in the DOM standard are named DOMxxx.

Many examples in this reference require an XML string. Instead of repeating this string in every example, it will be put into a file which will be included by each example. This include file is shown in the following example section. Alternatively, you could create an XML document and read it with DomDocument_open_file().

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 () 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.

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 you want to use XSLT extensions you have to copy "expat.dll" and "sablot.dll" into your windows-system directory.
closedfile

If you use IIS and Windows NT, pleace make sure that the file
"iconv.dll" is in the directory "winnt/system32/". Else you will get an error.

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.

Hey;

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)


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:

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
