Straight to the point:
It might make this a lot simpler for people to help me if I just say it like this:
I need to
-select all nodes in a branch of the xml file
-where one of the nodes in that branch
-contains a node with an attribute "navigateurl" that is equal to $RequestedPage
But if not please read on for my longer explanation of my problem!
I am using AspDotNetStorefront which makes use of XSLT transformations to do various things. I am having a problem with making a submenu that only shows sections of an xml file.
I have an xml menu that has <page> elements nested inside each other to form a sitemap style tree.
I have built an xslt that will recursively traverse the xml and transform this into a ul list.
The storefront also injects a separate node that contains the url of the currently requested page.
Question
--------------------------------------------
When I compare the <page> element to the current page variable I only want to show the <page> elements from that section of the tree. So if its a page halfway down the "about us" section of the tree I only want to show "about us" pages.
Please take a look at my xslt and tell me how I can pass the correct node-set to my template so that I only have one "branch" of the tree which is whichever branch the current page is in.
Example:
For this tree layout (presume that terms.aspx is the current page):
--home.aspx
--aboutus.aspx
---privacypolicy.aspx
---terms.aspx
--anotherunwantedsection.aspx
---unwantedpage.aspx
---unwantedpage2.aspx
How do I only get the about us branch?
--------------------------------------------
My XML File:
Note - the xml file is loaded into a larger set so that's why my xslt references this file as /root/MenuData/menu instead of /menu
HTML Code:
<?xml version="1.0" encoding="utf-8"?>
<menu>
<!-- NOTE - Do not prefix urls with / -->

How to select a branch of an xml file if it contains a node with a certain attribute?
