Hi

I have further questions on the fragments posted earlier. I did try implementing both options but had some questions ...

Q1. <snip>
<xsl:for-each-group select="current-group() except "." group-starting-with="*[@StyleName='DIVISION']">
</snip>

With this line of code, i found that it would execute (enter the for-each-group
loop) even if there wasn't a DIVISION item in the group. How do I stop the loop being entered if the group-starting-with entry is not in the list. I have tried an if statement after the loop has been entered but it is too late then for my purposes.

This reads to me like

<xsl:if test="current-group()/*[@StyleName='DIVISION']">
<xsl:for-each-group select="current-group() except "." group-starting-with="*[@StyleName='DIVISION']">
...
</xsl:if>

But I may have misunderstood the requirement. What do you want to happen
if there isn't a DIVISION item in the group?

Q2. <snip>
<Part Category="{@StyleName}">
<xsl:copy-of select="child::node()"/>
<xsl:for-each-group select="current-group() except ."
group-starting-with="*[@StyleName=f:child(@StyleName)]">
<xsl:apply-templates select="."/>
</snip>

With this piece of code from the second option where would you put the closing tags, where-ever i put them they would all output after everything else instead of in a nested fashion.

Clearly the XSLT must be well-formed XML, so the closing tags have to be
properly nested, and they will then also be properly nested in the
result document. In fact, it's impossible to output a document in which
the tags aren't properly nested! So I don't think I understand the
question.
