perl –MCPAN –e shellcpan>install XML::Simple
On a Windows system with ActivePerl, you can install these modules from the command line with the Perl package manager, like this:
ppm install LWP-SimpleThe only other piece you’ll need is a unique application ID from Yahoo!, which you can pick up at http://api.search.yahoo.com/webservices/register_application.
