RE: Constructing hierarchical XML from a flat XML-tag

Hi Lars,

	The easiest thing here is to use a key.

<xsl:key name="childrenNotSiblings" match="b|c|d"
use="generate-id(preceding-sibling::a[1])"/>

<xsl:template match="a">
  <a>
	<xsl:for-each select="key('childrenNotSiblings',generate-id())">
      		<xsl:copy-of select="."/>
	</xsl:for-each>
  </a>
</xsl:template>

If I've understood right you want to put all the non-a nodes that follow an
empty a node
inside it. Using a key will bundle all those nodes up and you can fetch them
using a reference
to the a node.

cheers,
Tom
