Moving on, how do I need to change my xpath to use pure xpath - no
variables? I want to visit each /root/w node and print the correct
/root/a/b/c value. I am getting the correct output, but have had to
rely on variable references.
The XSLT current() function points to the current node at the start
of the XPath expression.
I hope the example below helps.
