[CentOS] Where do I find perl XML::Parser module

Hi,
I am trying to install a package that requires the perl XML::Parser module.

So far I have:

Googled
Installed rpmforge and yum priorities
set priorities for all repositories used with rpmforge at 10
tried yum install perl-XML, yum install mod_perl-XML etc. and get 
response "Nothing to do"
so what is the correct yum request to get this package installed.

uname -a
Linux xxx.co.za 2.6.18-92.1.18el5xen #1 SMP Wed Nov 12 09:48:10 EST 2008 
x86_64 x86_64 x86_64 GNU/Linux

TIA
