Re: [xsl] dynamic variable name/implementation question

["Nathan Young" <natyoung@xxxxxxxxx>]

Hi.

I agree that the nodeset solution offered below is the most flexible  
solution (you can pass one in or load one with the document() function).   
Parsers differ in the way they handle this; using LibXML with perl I use  
the document function but haven't figured out how to pass a DOM as a param.

However, the way you describe passing things in using parameters  
constrains you to a fixed set of params defined in your stylesheet so you  
could go with a choose block in your template match.
