[jdom-interest] XPATH question

[Sanjeev Verma [CONTRACTOR]]

Hi all:

This is purely an XPATH question so others who may not be interested may please 
ignore.

I have a XML document in which I need to search for presence of certain keywords 
in certain tags. For example, here is a small snippet of the XML doc:

 <document id="20" type="INTERNAL" relevance="QA">
  <title>QA Doc</title>
  <author>Jason Hunter</author>
  <category level="1">QA</category>
  <submitted>Wed May 07 16:48:58 PDT 2003</submitted>
  <posted>Wed May 07 16:48:58 PDT 2003</posted>
  <keywords>QA, testing, software endurance</keywords>
  <summary>some summary...</summary>
 </document>

Now, the user may want to search for the presence of a keyword in title, author, 
keywords and summary. I am using XPATH to do this search, using the contains() 
function of XPATH. But the problem is, this search is case sensitive. Is there a 
equivalent function for case insensitive search also? What will be the best 
approach for doing this?

Please advice.

Best Regards
