GUID vs. LINK elements in RSS feeds

I'm reading an RSS feed whose entries contain both a GUID and a LINK element. For each entry, the GUID element contains a notes:// URL (that opens in Lotus Notes when clicked), and the LINK element contains an http:// URL.

For this feed, Mail and Safari display clickable hyperlinks that point to GUID. The LINK elements in the feed appear to be ignored. This means that when I click any of the links in the feed, it is opened in Lotus Notes instead of the default web browser I have chosen.

Is there any way to configure the way Mail and Safari parse and display feeds, so that the LINK element is displayed instead of, or in addition to, the GUID one?

Thanks!
