with XSLT 2.0 using distinct-values and Saxon extensions (saxon:evaluate)
me and my colleague Nick Ardlie, just created this code below yesterday to
list all unique elements and attributes for each element:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:saxon="http://saxon.sf.net/"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes" method="html"/>
<xsl:variable name="ROOT" select="root()"/>
<xsl:template match="/">
<html>
<body>
<h1>Elements</h1>
<ol>
<xsl:for-each select="distinct-values(//*/name())">
<xsl:sort order="ascending" select="."/>
<li>
<xsl:value-of select="."/>
<xsl:call-template name="LIST_ATTRIBUTES">
<xsl:with-param name="ELEMENT" select="."/>
</xsl:call-template>
</li>
</xsl:for-each>
</ol>
</body>
</html>
</xsl:template>
<xsl:template name="LIST_ATTRIBUTES">
<xsl:param name="ELEMENT"/>
<xsl:variable name="XPATH_EXPR"
select="concat('$p1//*[name()=''',$ELEMENT,''']/@*/name()')"/>
<xsl:if test="count(distinct-values(saxon:evaluate($XPATH_EXPR,
$ROOT))) > 0">
<h2>Attributes</h2>
<ol>
<xsl:for-each
select="distinct-values(saxon:evaluate($XPATH_EXPR, $ROOT))">
<xsl:sort order="ascending" select="."/>
<li>
<xsl:value-of select="."/>
</li>
</xsl:for-each>
</ol>
</xsl:if>
</xsl:template>
</xsl:stylesheet>

If you are stuck with 1.0 then you need to use a key:
<xsl:key name="names" match="*|@*" use="name()"/>
with
<xsl:for-each select="//*|//*/@*">
<xsl:if test="generate-id(.) = generate-id(key('names', name(.))[1])">
<xsl:value-of select="local-name()"/>
In 2.0 you can use distinct-values() or xsl:for-each-group, but it
always good to learn this technique.
