RE: Stupid XSLT tricks


xslt first instance
<xsl:value-of>, when applied to a node-set (in 1.0) outputs the string value
of the first node in the node-set.

Did you really want to evaluate count(//*) (the number of elements in the
document) when processing each element in the document? Better to put it in
a global variable. Ah, but I see the match="*" template is only executed
once, it doesn't recurse down the tree. You say you're trying to loop
through the XML instance but I see no code that attempts to do so.
