Re: [xsl] Re: Add element at the end of a variable group of elements

["Wendell Piez wapiez@xxxxxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

NB also Liam's variable could be recast as a function, to be namespace-safe:

<xsl:function name="z:is-early" as="xs:boolean">
  <xsl:param name="who" as="element()"/>
  <xsl:sequence
select="exists($who/(self::bar|self::foo|self::mercury|self::venus"/>
</xsl:function>

<xsl:template match="*[z:is-early(.)][last()]" priority="10">
  <xsl:next-match/> <!--* built-in template copies the element *-->
  <moon>Now with more craters!</moon>
</xsl:template>

Mind you, to drop a moon in where there is no planet at all would still
need a little 'pull' logic.

This is where a schema is quite useful, since a required element in a
sequence can provide a hook to hang things on.

Cheers, Wendell
