I haven't been following this thread, but...

No, this is completely wrong. <xsl:template match="..."> does not cause nodes to be processed. Only xsl:apply-templates and xsl:for-each do that. All you are doing when you provide a match template is saying that *if* the processor *happens* to be processing a node that matches given pattern, then this template *may* be applied. Processing begins at the root node of the source tree. If you don't provide a template that matches this node, then a built-in template containing just <xsl:apply-templates/> is invoked. xsl:apply-templates with no select means "go process each of the current node's children". There are built-in templates for each kind of node; the processor falls back on these if there is no better match. The spec explains what they are and how the best matching template for a given node is determined. > Select does not apply to xsl:template.

Not really. It tells the processor to go process all the attribute nodes on the current node (the Indice element being processed). The best matching template for each attribute is found and its contents instantiated. I'm stopping here. :) - Mike ____________________________________________________________________________ mike j. brown | xml/xslt: http://skew.org/xml/ denver/boulder, colorado, usa | resume: http://skew.org/~mike/resume/ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
