Im new to this forum so Im unable to post urls. (text & images) Please change in mind "kttp" into "http" and "vvv" into "www"

Im working with Visual Studio 2010 and try to debug an xsl file.
The debugger shows an error in a row where I try to convert an variable into a nodeset

<xsl:variable name="smcCollectedObjectsNodeset" select="xalan:nodeset($smcCollectedObjects)"/>

Here the debugger stops with XslTransformException "Cannot find the script or external object that implements prefix '

I defined the xalan namespace in the header of the xml file as you can see in the text.

<xsl:stylesheet version="1.0" xmlns:xsl="kttp://vvv.w3.org/1999/XSL/Transform" xmlnslm="kttp://vvv.plmxml.org/Schemas/PLMXMLSchema" xmlns:xalan="kttp://xml.apache.org/xalan" xmlns:lxslt="kttp://vvv.apache.org/xslt" xmlns:redirect="org.apache.xalan.lib.Redirect">
<xsl:variable name="reportHeader" select="'Mengenstueckliste fuer Maschinenteile (M)'"/>

I dont know how to solve this problem with visual Studio 2010?

Thanks, Mike
