Convert all element names to lower case with XSL?

Question

In XSL, how does one convert all element names in a document to lower case before processing it? We\'re using XSLT 2.0, and we\'ve tried the following but it does not work..

Answer 1

It works under Altova XMLSpy:

XSLT:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" >
<xsl:output exclude-result-prefixes="xsl xs" indent="yes"/>

  <xsl:template match="*">      
    <xsl:element name="{lower-case(local-name())}">
        <xsl:apply-templates/>
    </xsl:element>
  </xsl:template>    

</xsl:stylesheet>

XML Input:

<?xml version="1.0" encoding="UTF-8"?>
<A>
  <ITEMS>
    <ITEM/>
    <ITEM/>
  </ITEMS>
</A>

XML output:

<?xml version="1.0" encoding="UTF-8"?>
<a>
    <items>
        <item/>
        <item/>
    </items>
</a>

Answer 2

translate(local-name(), 'ABCDEFGHIJKLMNOPQRSTUVWXYZ", 'abcdefghijklmnopqrstuvwxyz')
