Re: [xsl] Slow XSLT

Hi,

No wonder you felt confused, I was wrong. Only after sitting down with
the problem I realized that this needs a recursive call for a named
template: it is used to produce one row  with apply-templates and then
go down one level. If we are at the bottom, process the Measures and
quit.
You will have no difficulty to add the attributes I left out for
readability. If you want to use $axisHeads = false() then the most
natural way would be to begin processing one level below by setting
	<xsl:variable name="set" select="Reports/Report/Columns/ColGrp/*"/>
Hope this helps,

Manfred
