RE: [xsl] Finding Nodes That Match Distinct Node Value

[<Trish@xxxxxxxxxxxxxx>]

Both solutions proposed work fine. Thank you for your help.

I went with using a key after all, since my XML file could get fairly
large over time. Here's an excerpt of the final code:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="html" indent="no" encoding="UTF-8"
doctype-public="-//W3C/DTD XHTML 1.0 Transitional//EN" />
<xsl:key name="keyFestival" match="Artist" use="@festival" />
<xsl:template match="/">

....

<table align="center" border="0" cellpadding="3" cellspacing="1">
   <tr align="left" valign="top">
      <td>artist</td>
      <td>date</td>
      <td>stage</td>
   </tr>
   <xsl:for-each
select="//Artist/@festival[not(.=preceding::Artist/@festival)]">
      <tr>
         <td colspan="3">
            <a name="{.}"></a>
