I am currently using xsl keys in my xsl document, to group child nodes
under
parent nodes. This is being run against an ADO recordset so my key looks
something like this :

<xsl:key name="rows-by-parent" match="z:row" use="@Parent_ID" />

My hierarchy can go several levels deep (about 10 levels are currently
supported). If any one of the children (n levels deep) of a level 1
parent
node(@Parent_ID = 0), has a variable @Exclude_YN = 'P' or Exclude_YN = 'C',
then I wish to display a text message next to that Parent Node, in my HTML
document.

I don't know how to apply the filter to child nodes n levels deep in the
hierarchy using an xsl:key. I am using keys to group currently.


thanx.

If the following xml is a good example of your document:

<z:foo xmlns:z="foo">
    <z:row ID="1" Parent_ID="0"></z:row>
    <z:row ID="2" Parent_ID="0"></z:row>
    <z:row ID="3" Parent_ID="1"></z:row>
    <z:row ID="4" Parent_ID="3" Exclude_YN = 'P'></z:row>
    <z:row ID="5" Parent_ID="2" Exclude_YN = 'C'></z:row>
</z:foo>

the following xsl produces the output:

Row Id: 1 contains P
Row Id: 2 contains C

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

         <xsl:key name="rows-by-parent" match="z:row" use="@Parent_ID" />

       <xsl:template match="/">

               <xsl:apply-templates select="z:foo/z:row[@Parent_ID='0']" />

       </xsl:template>

       <xsl:template match="z:row[@Parent_ID='0']">
               Row Id: <xsl:value-of select="@ID" />

               <xsl:apply-templates select="key('rows-by-parent', @ID)" />
            <br />
       </xsl:template>

       <xsl:template match="z:row[@Parent_ID!='0']">
               <xsl:choose>
                   <xsl:when test="@Exclude_YN='P'"> contains P </xsl:when>
                   <xsl:when test="@Exclude_YN='C'"> contains C </xsl:when>
               </xsl:choose>

              <xsl:apply-templates select="key('rows-by-parent', @ID)" />

       </xsl:template>

</xsl:stylesheet>

Hope that helps!
