Case insensitive XPATH

Question

Hi,
I have the following XMLs stored in a column.
<root>
<abc>abc</abc>
<def>def</def>
</root>
<root>
<ABC>abc</ABC>
<DEF>def</DEF>
</root>
Is there someway to use a case insensitive search in my extractValue so that I don't have to write it twice?
extractValue (XML_CLOB, /root/abc)
extractValue (XML_CLOB, /root/ABC)
Thanks and Regards,
A

Thought upper-case(name()) = "ABC" should work, but it doesn't seem to on 10.2Yes, fn:upper-case (and fn:lower-case) are XPath 2.0, EXTRACT and EXTRACTVALUE only implement XPath 1.0.
It will work with XQuery though, which includes XPath 2.0 :
WITH t AS (
  SELECT xmltype(
   '<root><ABC>abc</ABC><DEF>def</DEF></root>'
  ) doc
  FROM dual
SELECT xmlquery(
'root/*[fn:lower-case(name())="abc"]/text()'
passing by value t.doc
returning content
).getStringVal()
FROM t;
