note 13847 added to function.xslt-transform.php

The documentation is not very self explanatory for this function. After looking at the source code, here is a sample way of passing string versions of xml and xsl files, and passing parameters, such as ones passed through GET or POST: xslt_transform('arg:/xsldata', 'arg:/xmldata', 'arg:/', $HTTP_GET_VARS, array('xmldata' => $xml_data, 'xsldata' => $xsl_data), $result); echo $result; Further, if you include a file like "html.xsl" in the xsl data, you will need to add an extra array element like 'html.xsl' => $file_data so that the XSLT processor be able to access it. If you want to simply have the XSLT process read a file in, specify a regular URI for it like in the other functions. http://www.php.net/manual/en/function.xslt-transform.php
