Sorry all - wasn't too sure if anyone was actually listening that's all. I will proberly get butchered for this, but here is a development version of what I have so far.
First, the xslt file. Understand my knowledge of xslt is limited - I'm still learning this one:
PHP Code:
<?xml version='1.0' encoding='utf-8'?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

And now some example xml files I use:

Pheww... still with me ? 
Now some PHP to transform that xml file:
PHP Code:
function DoExecuteApp($menu, $command, $executable)
{

*/
$trans = new transform_xml;
$XML_DIR = '../apps/'. $_SESSION["OffManager"]["MenuState"] .'/templates/';
/**
* set xml directory and xsl stylesheet for this application
*/
$trans -> set_xml_dir($XML_DIR);
$trans -> set_xsl_file('admin-.xsl');
/**
* begin TABLE structure
*/
BeginTable('604', 'top', 'center');
if(strtolower($command) == (string) "home" || empty($command))
{
if(strtolower($executable) == (string) "usersearch") { UserSearch($trans); }
else if(strtolower($executable) == (string) "adduser") { AddUser($trans); }
else if(strtolower($executable) == (string) "doadduser") { DoAddUser($trans); }
else
{
$trans -> set_xml_file('admin-home.xml');
$trans -> append_function2_xml_file('<import />', 'ShowNumberMessages');
$trans -> make_xml_string();
}
}
/**
* close TABLE structure
*/
EndTable();
}
function ShowNumberMessages($obj = '')
{
/**
* functionality for search number of private messages this user has
*/
return $obj -> xml_enclose_tags('message-block', 'You have <bold>0</bold> new messages today.');
}
