Regular expression for parsing links from a webpage? *

Question

I'm looking for a .NET regular expression extract all the URLs from a webpage but haven't found one to be comprehensive enough to cover all the different ways you can specify a link.

And a side question:

Is there 'one regex to rule them all'? Or am I better off using a series of less complicated regular expressions and just using mutliple passes against the raw HTML? (Speed vs. Maintainability)

I took this from regexlib.com

[editor's note: the {1} has no real function in this regex; see this post]
