Hi Konrad,
For each <g> element I want to group the children into sub elements
based on the value of x, so like this:
You can use the Muenchian method with a key that uses a combination of
the identity (via generate-id()) of the <g> element and the value of
the x attribute. Try:
<xsl:key name="mykey" match="line" use="concat(generate-id(..), @x)"/>
<xsl:template match="g">
<xsl:variable name="this" select="generate-id()" />
<xsl:for-each select="*[count( . |
key('mykey',
concat($this, @x))[1]) = 1]">
<!-- build the inner g's -->
</xsl:for-each>
</xsl:template>
This should be faster since you're getting to the child elements
directly via the key rather than having to use the intersection
extension function.
Cheers,
Jeni
