Trying to grab certain info in RSS feed

[cronjob78]

In the code for an RSS feed below I want to grab the link in RED for an RSS feed rather than the one in BLUE that the code {rss.guid} gets in vBulletin.

Are there any tags I can use to pull this link out instead? Or any alternative suggestions like a way to parse the other link?

Many thanks for any help.
