Xpath problem with contain function

[White Shadow <ak...@hotmail.com>]

Hello Everyone

Thanks to Mark, I have been succeeded in implementing case-insensitive query 
string for my dbxml project. I am now facing a problem with contain function 
which I am using so that if a part of name is given for query, it can return 
me that as a valid result.

The query string I am using is:

xpath = "//person[contains(translate( 
Name,'ABCDEFGHIJKLMNOPQRSTUVWXYZ','abcdefghijklmnopqrstuvwxyz')=
translate('"+ strName + 
"','ABCDEFGHIJKLMNOPQRSTUVWXYZ','abcdefghijklmnopqrstuvwxyz'))]";

I want that for a name  Mark J. Stang , if the user queries for either Mark 
or Stang or J, it can return the Result for Mark J. Stang

The above xpath string is not working. Can someone point out whats teh 
mistake in it?

Thanks
