Imagine this scenario: You load an XML file (with configuration data) into the current session along with some custom methods to change data in the XML object in memory to , finally, save your changes.

But actually you can't use DOM Methods like dump_mem() after registering your DOM object in the current session.

Try this script:

-------------------------------------
<?php
session_start();

if (!isset($_SESSION['doc']))
  $_SESSION['doc'] = domxml_open_file('lalala.xml');

$_SESSION['doc']->dump_mem();
?>
<a href="<?=$_SERVER['SCRIPT_NAME']?>">click</a>
--------------------------------------

lalala.xml is a valid xml file.

This is not possible and most presumably never will be possible. We would have to store the actual xml-data somewhere, but php knows only the pointer to the xml-data which is handled by the libxml2-library and this stuff gets freed after script-end.

you have to parse and save it everytime or use your own xml-structure built with php-objects, like maybe XML_Tree from PEAR (never tested that, though)
