[xsl] Dynamic XPath expression (I know it doesnt work in XSLT1.0)

[Matt Dittbenner <mbditt@xxxxxxxxxxxxxxxxx>]

Hello,

After some pretty exhaustive searching on the web, I have decided to 
join the list. I have noticed in the archives that more than one person 
has had the same issue as I have...how to create an XPath expression 
dynamically (from a variable, etc). The answer to these questions was to 
use any of the available *:evaluate functions. I would like to try to 
avoid that, since it increases the parse time so much....and that is not 
acceptable.

My question is if there is any other way to accomplish this, for example 
using XSLT2.0. I have found little information about the newer XSLT 
recommendation, and the information I have found is fairly cryptic (at 
least to me). Here is a more detailed example of what I am trying to do:

===================================
doc.xml
<tag2>Data I want...</tag2>

template.xhtml
<p>
   <getContent path="tag2/text()"/>
</p>

stylesheet.xsl
<xsl:variable name="path" select="/p/getContent/@path" />
<xsl:value-of select="document('doc.xml')/$path"/>
===================================

In an ideal world, stylesheet.xsl would use the XPath expression from 
the attribute in template.xhtml to access another document (doc.xml) and 
then grab the data located there. How do I do this?!

Thanks in advance,
Matt Dittbenner
