[xsl] Re: (Probably trivial) grouping problem

["Dimitre Novatchev" <dnovatchev@xxxxxxxxx>]

Use the following transformation:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:strip-space elements="*"/>

 <xsl:key  name="kFollParas" match="para[not(@title)]"
  use="generate-id(preceding-sibling::para[@title][1])"/>

  <xsl:template match="para[@title]">
    <section>
      <title><xsl:value-of select="@title"/></title>
      <para><xsl:value-of select="."/></para>
      <xsl:copy-of select="key('kFollParas', generate-id())"/>
    </section>
  </xsl:template>
  <xsl:template match="para[not(@title)]"/>
</xsl:stylesheet>


When applied on your source.xml:

<text>
  <para title="title1">
        some text
  </para>
  <para>
        a para without a title
  </para>
  <para title="title2">
        more text
  </para>
  <para>
        yet another untitled para
  </para>
</text>


the wanted result is produced:

<section>
   <title>title1</title>
   <para>
        some text
  </para>
   <para>
        a para without a title
  </para>
</section>
<section>
   <title>title2</title>
   <para>
        more text
  </para>
   <para>
        yet another untitled para
  </para>
</section>


Hope this helped.
