LWP (for "Library for WWW in Perl", also called libwww-perl) is a set of Perl modules that give Perl programming easy access to sending requests to the World Wide Web.

Howto update in Strawberry perl: open CPAN

perl -MCPAN -e shell

Search for a library, for example LWP:

i /libwww/

This gives you a list, you can install one (for me this is)

install GAAS/libwww-perl-5.837.tar.gz

You can also search for the XML::Simple

i /XML::Simple/

I get a list and I can install from:

install GRANTM/XML-Simple-2.20.tar.gz

Now you can type "exit" to get out of CPAN and try to use XML::Simple;
