RE: Process node set generated by EXSLT tokenize

Mat,

You were on the right track using the tokenize function, you just need to
capture the result of the template call.  What you need to do is wrap your
call-template call in a variable and then use the node-set extension function
to
do work on those newly created nodes.

For example,
<xsl:variable name="siteNodes">
	<xsl:call-template name="tokenize">
		<xsl:with-param name="string" select="@exsites" />
		<xsl:with-param name="delimiters" select="','" />
	</xsl:call-template>
</xsl:variable>

Will create a variable with the structure:
<exsite>17</exsite>
<exsite>21</exsite>
<exsite>32</exsite>

You then need to use the node-set extenstion function of your XSLT processor.
If you are using MSXML it would look like:

<?xml version="1.0" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

xmlns:msxml="urn:schemas-microsoft-com:xslt">

...

	<xsl:for-each select="msxml:node-set($siteNodes)/exsite">
		Do something here
	</xsl:for-each>
</xsl:stylesheet>

If you're on a different processor you'll have to look up the correct
namespace
URI for the processor.

Hope this helps.

Subject:  Process node set generated by EXSLT tokenize

I built a simple XSL stylesheet for a css-based
sidebar navigation. The navigation will appear on
several co-branded sites, so each link's XML element
has an attribute that specifies the link's display
status. For example:

<menu name="name" url="" includeSites="0"/>

I use an <xsl:if> statement to compare the attribute
against a "siteID" parameter. If there's a match, then
the link is displayed. A <xsl:for-each> iterates
through each link. No problem.

My project has a new requirmenet. The includeSites
attribute may have muliple, comma-delimited values.
For example:

<menu name="name" url="" includeSites="17,21,32"/>

I utilized the EXSLT tokenize() template to build a
node set out of the delimited attributes. However, I'm
new to XSLT and I can't grasp how to process that node
set. This is the XHTML that my stylesheet is currently
generating:

<ul><includeSite>0</includeSite><li><a href="">Link
1</a></li><includeSite>17</includeSite><li><a
href="">Link 2</a></li>...</ul>

What I want is for the node set values to be passed to
an <xsl:if> statement that's iterated by an
<xsl:for-each>, like I have in my single-attribute
version. If this were JavaScript, I would pass the
node value as a variable, but that doesn't seem
possible in XSLT.

I have examples of my code posted if my language isn't
clear:

Is this task even within the capabilities of XSLT 1.0?

Thanks,
