RE: [xsl] Collecting sibling nodes under groupings

["Michael Kay" <mike@xxxxxxxxxxxx>]

Right, well that's a standard grouping problem then:

<xsl:for-each select="Entry" group-by="Subject">
  <Subject>
    <xsl:value-of select="current-grouping-key()"/>
    <xsl:copy-of select="current-group()/Title">
  </Subject>
</xsl:for-each>

It won't replicate your indentation but should be otherwise OK.
