Hi Daniel,

Using Muenchian technique something like this...

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:key name="kDistinctElementNames" match="foo/*" use="local-name()"/>

<xsl:template match="/">
  <xsl:apply-templates/>
</xsl:template>

<xsl:template match="foo">
  <xsl:copy>
    <xsl:for-each select="*[generate-id() =
generate-id(key('kDistinctElementNames',local-name()))]">
      <xsl:copy/>
    </xsl:for-each>
  </xsl:copy>
</xsl:template>
</xsl:stylesheet>


Although I suspect that that isn't really what you are after?  Perhaps what
you are trying to do is build an output that has a summary structure
(excluding repetitions) of the input document?  For example, what would you
want the output for the following XML to look like?...

<?xml version="1.0"?>
<foo>
  <foo2/>
  <bar>
    <a/>
    <a/>
    <a/>
    <b i="1"/>
    <b i="1"/>
    <c x="x">
      <xxx a="1"/>
      <xxx a="2"/>
      <yyy b="1"/>
    </c>
    <c x="y">
      <xxx a="3"/>
      <yyy b="2"/>
    </c>
    <c x="z">
      <yyy b="3"/>
      <zzz c="1"/>
    </c>
  </bar>
</foo>

perhaps you are looking for an output something like?...

<?xml version="1.0"?>
<foo>
  <foo2/>
  <bar>
    <a/>
    <b/>
    <c>
      <xxx/>
      <yyy/>
      <zzz/>
    </c>
  </bar>
</foo>

If so, then this can be done - but gets pretty complex ;)  But do say if
that's the end goal - I may have something that does that or about that.
