XML transition from PHP4 `domxml` to PHP5 `dom`

When moving from PHP4 to PHP5, some modifications are required in the scripts. In PHP4, the experimental domxml extension was used to manage XML, but this has been replaced by the dom extension in PHP5.

Migration from PHP4 to PHP5 is easy, but might be long if domxml was broadly used. Moreover, in order to have a smooth transition, it is good for scripts to be compatible with PHP5 as soon as possible, even if the server is still running PHP4. The optimisation for PHP5 can be done later.

I propose on this page a module (wrapper) to include in your PHP4/domxml scripts, for them to be compatible with PHP5/dom or PHP6/dom.

For XSLT/XSL, have a look to my PHP4/XSLT to PHP5/XSL page.

Scripts for PHP4 `domxml` compatible with PHP5 `dom`

In order to run your PHP4 scripts that use domxml on a server moving to PHP5, you only need to include the file domxml-php4-to-php5.php in your PHP4 source code, this way:

if (PHP_VERSION>='5')
 require_once('domxml-php4-to-php5.php');

Download domxml-php4-to-php5.php (1.23 2011-11-19)

Note that it does not modify your scripts when the server is still running PHP4.
It is covering the main domxml functions, but not all of them. Nevertheless, it can easily be extended if needed.
Bellow, an example and the code for the compatibility file.

exemple-php4.php

<?php
//PHP4 script using domxml extension
//We want to make it run on PHP5 with dom
if (PHP_VERSION>='5')
 require_once('domxml-php4-to-php5.php'); //Load the PHP5 converter
if ($dom=domxml_open_file('test.xml'))
{
 $root=$dom->document_element();
 $bs=$root->get_elements_by_tagname('body');
 if (count($bs)==1)
 {
  $body=$bs[0];
  $p=$dom->create_element('p');
  $p->append_child($dom->create_text_node('a new paragraph'));
  $body->append_child($p);
  $body->append_child($dom->create_text_node("\n"));
 }
 $dom->dump_file('test.xml',false,false);
}
?>

domxml-php4-to-php5.php

<?php
/*
 To be used in PHP4 scripts using DOMXML extension.
 Allows PHP4/DOMXML scripts to run on PHP5/DOM.
 Requires PHP5, uses built-in DOM extension,
  needs XSL extension (included in PHP5) for domxml_xslt functions,
  needs PHP>=5.1 for full XPath evaluation support,
  needs PHP>=5.1/libxml for DOMXML error reports.
