Re: XSLT: Selecting nodes based on a group of other nodes

["Mark Sztainbok" <sz@xxxxxxxxxxxxxx>]

That's not exactly what I'm looking for. What I need to do is store the node
list into a variable so that something like the following can be done:

<xsl:choose>
    <xsl:when test="/RESPONSE/FILTERED">
        <!-- Set products variable to products that have corresponding
SELECTEDPRODUCT nodes -->
        <!-- Insert my attempts to code here -->
    </xsl:when>
    <xsl:otherwise>
        <!-- Set products variable to all the products -->
        <xsl:variable name="products" select="/RESPONSE/PRODUCT"/>
    </xsl:otherwise>
</xsl:choose>
<xsl:for-each select="$products">
    <!-- Process products here -->
</xsl:for-each>

Any ideas of how to set the products variable in the first case given the
description of what I want to do that I gave in my first email?

Thanks,

Mark
