I want to nest sections from a flat XML file based on the value of a section attribute. I have done this before with a similar but slightly different situation. I'm missing something with the behavior of xsl:for-each-group.
<xsl:template match="/">
<xsl:variable name="unflattenedDoc">
<book>
<xsl:copy>
<xsl:for-each-group select="*" group-starting-with="section[@label=1]">
T:\ftemp>type steve.xml <?xml version="1.0" encoding="UTF-8"?> <book type="Tech_Manual"> <bookinfo> <title>client manual</title> <subtitle>performance data</subtitle> </bookinfo> <section id="a--21" label="1"> <title lang="en">Preface</title> <para>some interesting stuff</para> </section> <section id="a--22" label="2"> <title lang="en">Preface</title> <para>some more interesting stuff</para> </section> <section id="a--23" label="2"> <title lang="en">Preface</title> <para>some more interesting stuff</para> </section> <section id="a--24" label="3"> <title lang="en">Preface</title> <para>some more interesting stuff</para> </section> <section id="a--25" label="1"> <title lang="en">Cautions</title> <para>some interesting stuff</para> </section> </book>
