I keep forgetting about an XSLT function called current().
<xsl:for-each select="//Artist[(_at_)festival = current()]">
will also work.
If you use current(), you don't have to create <xsl:variable
name="CurrentFestival" select="."/>

Hi Trish,
The issue is a context issue. When you write:
<xsl:for-each select="//Artist[(_at_)festival = .]">
the '.' inside the predicate refers to the Artist node being being
filtered with the predicate.
You need to save the current Festival in a variable and use this.
A simplified version of the template that does what I think you want:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:template match="/">
<xsl:for-each select="//Artist/@festival[not(.=preceding::Artist/@festival)]">
<xsl:value-of select="concat('Festival=',.,'
')"/>
<xsl:variable name="CurrentFestival" select="."/>
<xsl:for-each select="//Artist[(_at_)festival = $CurrentFestival]">
<xsl:value-of select="concat(' Artist=',@name,' Date=',Date,'
Stage=',Stage,'
')"/>
</xsl:for-each>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
Output is:
Festival=2007
Artist=John Doe Date=08/17/07 Stage=Stage Two
Artist=Jane Doe Date=08/15/07 Stage=Stage Three
Artist=Dick Doe Date=08/16/07 Stage=Stage One
Festival=2006
Artist=Sally Doe Date=08/16/06 Stage=Stage Four
Artist=John Q. Public Date=08/15/06 Stage=Stage One
Festival=2005
Artist=John Smith Date=08/17/05 Stage=Stage Three
Festival=2004
Artist=Jane Smith Date=08/17/04 Stage=Stage Four
Artist=Sally Smith Date=08/16/04 Stage=Somethin' Else
Artist=Dick Smith Date=08/16/04 Stage=Stage Two
