Hi Lionel,
  Please try the following XSL -

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xalan="http://xml.apache.org/xalan">

<xsl:output method="xml" version="1.0"
encoding="UTF-8" indent="yes"/>
	
<xsl:key name="by-num" match="/root/*" use="name()"/>
<xsl:key name="by-alphabet" match="/temp/*"
use="name()"/>
	
<xsl:template match="/root">
   <xsl:for-each select="*">
     <xsl:if test="generate-id(.) =
generate-id(key('by-num', name())[1])">
	<xsl:element name="{name()}">
          <xsl:variable name="rtf1">
	    <temp>
	      <xsl:for-each select="key('by-num', name())">
		<xsl:copy-of select="child::*"/>
	      </xsl:for-each>
	    </temp>
	  </xsl:variable>	  
          <xsl:variable name="rtf2">
	    <temp>
	      <xsl:for-each
select="xalan:nodeset($rtf1)/temp/*">
		<xsl:if test="generate-id(.) =
generate-id(key('by-alphabet', name())[1])">
		  <xsl:element name="{name()}"/>
		</xsl:if>
	      </xsl:for-each>
	    </temp>
	  </xsl:variable>
	  
          <xsl:for-each
select="xalan:nodeset($rtf2)/temp/*">
	    <xsl:sort select="name()" />
	    <xsl:element name="{name()}" />
	  </xsl:for-each>
      </xsl:element>
   </xsl:if>
</xsl:for-each>

</xsl:template>
	
</xsl:stylesheet>

<1>, <2> are not valid XML tag names. 

I tested the XSL with the following XML -

<?xml version="1.0" encoding="UTF-8"?>
<root>
   <one>
    <a/>
    <b/>
   </one>
   <two>
    <a/>
   </two>
   <three>
    <b/>
    <c/>
   </three>
   <one>
    <a/>
    <c/>
   </one>
</root>

and got the output -
<?xml version="1.0" encoding="UTF-8"?>
<one>
  <a/>
  <b/>
  <c/>
</one>
<two>
  <a/>
</two>
<three>
  <b/>
  <c/>
</three>

Regards,
Mukul
