(i left out the top level elements and started with the topmost div):which meant the stylesheet as posted didn't select anything.
I suspect that your only problem is that 10 is sorting before 3 as it's doing strings not numbers. <xsl:sort data-type="number" select="@n"/>
I can't readthis xml by eye to really spot what is being sorted where but i get:
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" exclude-result-prefixes="xs">
<xsl:strip-space elements="*"/>
<xsl:output indent="yes"/>
<xsl:template name="body">
<xsl:variable name="docs" as="node()*" select="document(('file1.xml','file2.xml'))"/>
<xsl:variable name="divs" as="node()*" select="$docs/div"/>
<xsl:for-each-group select="$divs" group-by="@id">
<div type="{current-grouping-key()}" id="{current-group()[1]/@id}">
<xsl:apply-templates select="current-group()[1]/head"/>
<xsl:for-each-group select="current-group()/node()" group-by="@id">
<div type="{current-group()[1]/@type}" id="{current-grouping-key()}" n="{current-group()[1]/@n}">
<!-- I want to insert a xsl:sort here so that i can sort the current-group() according to the @n -->
<xsl:apply-templates select="current-group()[1]/head"/>
<xsl:for-each-group select="current-group()/div" group-by="@n">
<xsl:sort data-type="number" select="@n"/>
<div type="{current-group()[1]/@type}" id="{current-group()[1]/@id}" n="{current-grouping-key()}">
<xsl:apply-templates select="current-group()[1]/head"/>
<xsl:apply-templates select="div"/>
</div>
</xsl:for-each-group>
</div>
</xsl:for-each-group>
</div>
</xsl:for-each-group>
</xsl:template>
<!-- indentity template here --> <xsl:template match="*"> <xsl:copy-of select="."/> </xsl:template> </xsl:stylesheet>
