How do I go about parsing a url from the browser location. For example if I have the 
following url:

https://mercedissa.tmo.org/cgi-bin/req/sreq_start.pl?sid=EBSCO:buh%20(Via%20SFX)&genre=article&issn=00999660&volume=242&issue=26&date=2003&atitle=S.O.S.%20Africa.&title=Wall%20Street%20Journal%20-%20Eastern%20Edition&spage=A12&aulast=Waal&aufirst=Alex

As you can see there are elements like volume, genre, date, issue, title, author.....

How do I parse this to get only the elements mentioned above? Is there a perl module 
that does this?

Thanks.
