Case Insensitive Search - XPATH?

[Mapper99]

I can't seem to get a PHP case insensitive search to work using an XPATH query.

This code works (case sensitive):

$lats = $users->xpath("/users/user[contains(.,'$fullname')]/lat");

This code does not work:

$lats = $users->xpath("/users/user[contains(translate(.,'abcdefghijklmnopqrstuvwxyz'," + " 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'),'$fullname')]/lat");

Any ideas? Is this the correct approach?

Thanks in advance,

Mapper
