Do you mean that you'd like to select nodes based on their
attribute names or values, but in a case-insensitive manner?

See below.

That's basically correct, for English.  You may wish to

use the XSLT Standard Library's to-lower template in order

to handle non-English case folding.


Unfortunately, XSLT v1.0 doesn't provide a way of defining
a function in the stylesheet so we have to do things the
hard way.  If I'm looking for the attribute named 'foo',
but in any permutation of case ('Foo', 'FOO', etc), try this(*):

<xsl:template match='*'>
   <xsl:for-each select='@*'>
     <xsl:variable name='lower'>
       <xsl:call-template name='str:to-lower'>
         <xsl:with-param name='text' select='.'/>
       </xsl:call-template>
     </xsl:variable>

     <xsl:if test='$lower = "foo"'>
       <!-- This is the one I want -->
     </xsl:if>
   </xsl:for-each>
</xsl:template>

Of course, using translate() is much more succinct:

<xsl:template match='*/@*[translate(., "ABC...", "abc...") = "foo"]'>
   <!-- This is the one I want -->
</xsl:template>

but as I mentioned above doesn't handle case-folding in general.

* You must setup XSLTSL to work in your stylesheet.
   See http://xsltsl.sf.net/ for instructions on how to do that.
