Re: [xsl] Merging multiple documents and combining their nodes

Thanks Martin!

David:

Is the following what you had in mind?  The first template retrieves
the components/component node-sets from the files listed in the
filenames_file.xml document. The template defines this node-set as the
temp variable.

The second template organizes the information in the temp variable.

<xsl:stylesheet version="1.0"
         xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
         xmlns:exslt="http://exslt.org/common";>
	<xsl:output indent="yes"/>
	<xsl:template match="/">
		<xsl:variable name="temp">
			<components>
				<xsl:copy-of
select="document(document('filenames_file.xml')/files/file)/components/component"/>
			</components>
		</xsl:variable>
	</xsl:template>	
	
	<xsl:template match="/">
		<components>
			<xsl:for-each select="exslt:node-set($temp)/components/component">
				<xsl:sort select="@name"/>
				        <name>
						<xsl:value-of select="@name"/>
					</name>
                                       ..
			</xsl:for-each>
		</components>
	</xsl:template>
</xsl:stylesheet>


When I apply the stylesheet, Xalan displays an error: "Could not find
variable with the name of temp."  I presume the error is arising
because the second template cannot find the temp variable defined in
the first template. Would you agree?  If so, how could the issue be
resolved?

Thanks,
Mark
