Andrew,
what warning would you hope to see?

Dear xsl-list,
I am attempting to group the following using XSLT 2.0. Here is a
snippet of the XML (edited for readability):
<?xml version="1.0"?>
<Root>
<State>
<!--first standard; first lesson-->
<Standard>
<SS id="1.4.1">1.4.1 standard text </SS>
<Lesson>Prefixes and Suffixes</Lesson>
</Standard>
<!--same standard as first; new lesson-->
<Standard>
<SS id="1.4.1">1.4.1 standard text</SS>
<Lesson>Root Words</Lesson>
</Standard>
<!--new standard; new lesson-->
<Standard>
<SS id="1.4.2">1.4.2 standard text</SS>
<Lesson>Context Clues</Lesson>
</Standard>
<!--two standards grouped with one lesson-->
<Standard>
<SS id="1.4.5">1.4.5 standard text/SS>
<SS id="1.4.6">1.4.6 standard text</SS>
<Lesson>Synonyms</Lesson>
</Standard>
. . .
</State>
</Root>
Here is what I am seeking:
<!--Lessons grouped after common standard-->
<Standard>
<SS id="1.4.1">1.4.1 standard text </SS>
<Lesson>Prefixes and Suffixes</Lesson>
<Lesson>Root Words</Lesson>
</Standard>
. . .
<!--grouped standards separated-->
<Standard>
<SS id="1.4.5">1.4.5 standard text </SS>
<Lesson>Synonyms</Lesson>
</Standard>
<Standard>
<SS id="1.4.6">1.4.6 new standard grouped with preceeding
sibling</SS>
<Lesson>Synonyms</Lesson>
</Standard>
So far I have been able to group the <SS> elements using for-each-group:
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="xml" indent="no"/>
<xsl:template match="State">
<xsl:for-each-group select="Standard/SS" group-by="@id">
<xsl:for-each select="current-group()"/>
<xsl:copy-of select="."/><xsl:text> </xsl:text>
</xsl:for-each-group>
</xsl:template>
</xsl:stylesheet>
When I try to work in the <Lesson> elements, I get the entire
standards listing.
I have also wondered if I need to first separate the grouped standards.
Any help would be appreciated.
Terry
