Finding the RSS Feed

[Roamer]

On blogs, you have an RSS Feed.

In the heading of the page (usually the homepage) there is this:

<link rel="alternate" type="application/rss+xml" title="RSS 2.0" href="http://anydomain.com/somekindofname.xml">
 

Note: there is no way of knowing the exact name of the feed, from the site url alone. It has to be found.

Using Perl
Is there a simple way to find the above tag, then extract the URL of the feed from the href?
Preferably without having to use any modules.

I haven't got the remotest clue how to do this.

I will have the URL of a blog, so no problem on that score. Once I have the URL of the feed, I'm okay from there.

I sure hope someone can help, thanks.
