Re: [xsl] xsl:for-each-group and identity transform

[Jesper Tverskov <jesper.tverskov@xxxxxxxxx>]

To make me more clear. I have made an "unflatten.xsl" using Michael
Kay's code in 4th edition of "XSLT 2.0 and XPath 2.0", page 340,  as
point of departure. I have modified it to get real XHTML input
working.

I think my stylesheet works, but I run into the good old problem of
attributes being copied out of the DTD. So I was looking for a way to
get additional templates in place to delete those attributes again as
I use to do when making an identity transform. But I have only managed
to do so in a second transformation.

So here is my question: Is it possible to get both the
xsl:for-each-group and a modified identity transform working in one
transformation?

group-starting-with="h1">
<xsl:apply-templates select="." mode="group"/>
</xsl:for-each-group>
</xsl:copy>
</xsl:template>
<xsl:template match="h1" mode="group">

</xsl:for-each-group>
</xsl:template>
<xsl:template match="h2|h3|h4|h5|h6" mode="group">
<xsl:variable name="this" select="name()"/>
<xsl:variable name="next" select="translate($this, '23456', '34567')"/>
<section>
<h>
<xsl:copy-of select="descendant::node()"/>
</h>
<xsl:for-each-group select="current-group() except ."
group-starting-with="*[name() = $next]">

</xsl:for-each-group>
</section>
</xsl:template>
<xsl:template match="element()|comment()|processing-instruction()" mode="group">
<xsl:copy-of select="current-group()"/>
</xsl:template>
</xsl:stylesheet>
