I've set a variable, $mynode. it's a node deep down in the tree. I found it by doing this:

<xsl:variable select="//node[@id=$myval]" name="mynode"></xsl:variable>

As I iterate through some child nodes in another template, I want to know if the current node is an ancestor of $mynode.

it'll be some use of ancestor-or-self:: or decendent::

I've been hacking away at this Xpath for over an hour to find the right condition, but it's eluding me.

help!
