Hi there,



Overlooked the fact that you were using concat. Sorry.



But I think the concat is not used properly. From you comment below, I understand that you try to 
concatenate two parts of an XPath expression and to evaluate that. In you code you are actually 
retrieving the document and combining the string value of the full document with the second part of 
the XPath expression:



	<xsl:variable name="mainXML_node" select="document('../XML/PM-EA-AA_IA_PA_TA.xml')"/>
	(...)
	<xsl:for-each-group select="concat($mainXML_node,$path)" group-by="@SAObjName">
	(...)

You probably want to do something like:



<xsl:variable name="xpath">
  <xsl:text>document('../XML/PM-EA-AA_IA_PA_TA.xml')</xsl:text>
  <xsl:value-of select="@XPath" />
</xsl:variable>

<xsl:for-each-group select="saxon:evaluate-to-node($xpath)" ... >



Cheers,
Geert

Hello,



No, the /Classes/Clas... Found within the @Xpath attribute is simply a string. The idea is to find a way to concatenate a root node and this xpath string, then evaluate it. -> document(Xxx.xml)/Classes/Class/...
					        (     is a node       )(    is a string    )  --> (must be a nodeset)

I suspect that the path '/Classes/..' is not evaluated with the external document as context, but 
the one passed from source of command-line. But I'm not a Saxon expert.



Have you tried relative paths?
