Re: XML::XPath

[Geert J. <Geert.Josten@Daidalos.nl>]

Yes, a resulting node-set is incompatible... I was only thinking that far most xpath-expressions are used to select a value with xsl:value-of. That function always returns one of the simplest variable types, string or number... In those cases the result of XPath is just the value.

Oh, I forgot that XPath is also used for xsl:variable, one can store the resulting node-set in a variable. Maybe it is possible to manipulate the resulting tree so that becomes a DOM-tree. If the structures resemble each other enough, it might even be done relatively quick.

Other alternative: parse the XPath expression and construct a block of perl-code to retrieve the set, saving as much variable usage as possible and saving many function-calls as well. Though the parsing itself may cancel the gain of speed...
