Tutorial for XML for Perl
The Perl scripting language can be used to perform two important tasks: reading and writing XML files. Extensible Markup Language, or XML, is a customized program file that is used store data. It always stores its data in the same structure, so that its easy for software engineers to predict what can be used inside the XML file. This tutorial will show you how to create an XML parser in Perl, a tool that can be used to break-down XML files and read what's inside of them.

use LWP::Simple
my $message

Build the portion of the parser that grabs the URL of the XML file and parses it by using the following lines of Perl code:
my $sportsnews = get(http://http://www.examplesportswebsite.com");
