Forum:Regular expression for AWB to turn outbound links to wikipedia to interwiki links

I've noticed that GuildWiki has several links to wikipedia using the url http://en.wikipedia.org, instead of the interwiki wikipedia:. As linking to en.wikipedia.org directly invokes the wrath of special:outbound, leading to problems, I'd like to rename all of those links to outbound links. However, I don't know Regex. Can anyone help me craft an expression for AWB that'll turn: bar into bar Thanks, -- Random Time  09:46, September 5, 2010 (UTC)
