Re: Getting a distinct list of node names

Maybe this cannot be accomplished with plain Xslt

I need to get a distinct list of the node names from all children of one
node. For example, if I have:

    <node:definition>
        <form:validator />
        <form:validator />
        <form:filter />
    </node:definition>

I want to be able to retrieve a list of the names of all tags used
within node:definition. However, it should contain each tag name only
once:

('form:validator', 'form:filter')

T:\ftemp>type manuel.xml
<?xml version="1.0" encoding="iso-8859-1"?>
<node:definition xmlns:node="node" xmlns:form="form">
  <form:validator/>
  <form:validator/>
  <form:filter/>
</node:definition>

T:\ftemp>type manuel.xsl
<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                version="1.0">

<xsl:template match="*[*]">
  <xsl:value-of select="name(.)"/>:<xsl:text/>

  <xsl:variable name="childnodes" select="*"/><!--all children-->
  <xsl:for-each select="$childnodes">
    <xsl:if test="generate-id(.)=
                  generate-id($childnodes[name(.)=name(current())])">
      <xsl:text/> '<xsl:value-of select="name(.)"/>'<xsl:text/>
    </xsl:if>
  </xsl:for-each>

  <xsl:text>
</xsl:text>
  <xsl:apply-templates/>
</xsl:template>

T:\ftemp>saxon manuel.xml manuel.xsl
node:definition: 'form:validator' 'form:filter'
