Sablotron Error Code 72

I am getting a Sablotron error regarding an unbound namespace

[bc5211]

I am trying to figure out how to resolve this error:

Warning: Sablotron error on line 84: excluded prefix 'xmlns' is not bound to any namespace in C:\Program Files\Apache Group\Apache2\htdocs\irXml\clientFiles\cyto\php\PressReleaseList.php on line 21
Sablotron Error Code 72

Line 21 of my PHP file is my call to the xslt_process() function:

$result = xslt_process($xh, 'arg:/_xml', '../Apache2/htdocs/irXml/clientFiles/cyto/xsl/PressReleaseList.xsl',NULL,array("/_xml"=>$xml),$params);

My XSL file works fine when I use the same one with both ASP and JSP pages I have written, so I know that is not the problem. Can anyone shed some light on this?

Thanks!

Have you tried looking at [php.net...] .? There's some info about Sablotron.

Hope you can find some answers there

I didn't find a ton in the PHP documentation but I will look again! In me meantime, if anyone else has a solution to this it would be much appreciated!
