yes

Shortest post ever:)

You could install it from cpan or find a strawberry package for it.

Strawberry is different from ActiveState in that it does match closely to the way that Unix ports behave, and it accepts the use of CPAN to install CPAN packages, which generally work just as expected. It's a bit of a surprise how you must set up environment variables like PERL5LIB (you have to use an obscure system control-panel feature), but otherwise it works out very much like "using Perl as a non-root user."

Strawberry also proivides PPM to install modules, I think that's what dHarry means by "package".

You can obtain for yourself the answer, try and run

use warnings;
use xml::simple;
[download]

If is not installed still, perl probably will show something like this:

Also see Re: use Strict: a rigorous way to break my command line variables?.

If XML::Simple is installed, use xml::simple; on Windows will not raise an error related to xml::simple or XML::Simple:

>perl -Mxml::simple -e "XMLin()"
Undefined subroutine &main::XMLin called at -e line 1.

>perl -MXML::Simple -e "XMLin()"
Could not find -e.xml in .\ at -e line 1
[download]

Because file systems on Windows are generally case insensitive, you can load modules under various names. As package names under Perl still are case sensitive, their ->import() method will not be called, which is confusing.

In my opinion, it would have been more helpful to directly tell the OP that there is no module xml::simple.
