HTML Fetch based on user field

[barryhand]

Here's what I'd like todo.

Grab html based on a users customfield - http://www.site.com?id=($customfield)

parse this html, returning 4-5 bits of information, and put it back into a table.

The information I need put back into a vB table is

Userid, Username, and 4-5 bits of information parsed from the fetched html.

Any pointers?
