Changing variables in match templates

Hi,

I hope you can help. This example should hopefully explain my problem.

I have an XML document (the default document) that contains a list of XML files and an XPath expression in an attribute for each one. Each file is loaded by the match="/" template in a for-each loop using the document function to load the XML into a variable.

I then call <apply-templates select="fileDoc" mode="copy"/>

This copies each file (and does some filtering but I'm not concerned about that in this example). However, I need to reference the XPath of the file that I've stored in a variable in the main for-each loop but isn't accessible from the

Code:

<xsl:template match="*" mode="copy">

or

Code:

<xsl:template match="@*" mode="copy">

templates as I can't pass paramters.

I'm using Saxon so have access to XSLT / XPath 2.0 functionality. I have tried to use saxon:assign but failed totally to get it to work as the

Code:

saxon:expression()

function fails to look up the variable saying

Code:

"Variable $msgCtx has not been declared"

Also, this simple xsl

Code:

<xsl:variable name="myXPath" select="'/'"/>
<xsl:variable name="result" select="saxon:expression($myXPath)"/>
<xsl:message>Result = <xsl:copy-of select="$result"/></xsl:message>

produces

Code:

Result = net.sf.saxon.functions.Evaluate$PreparedExpression@179f36b

as output!?

Can anyone help?

Thanks.
