Regex / Yahoo Pipes - Match first word after an expression

I'm basically trying to do the same thing as in this example - How to match the first word after an expression with regex? - but within Yahoo Pipes.

I've test开发者_如何学Pythoned the answered coded in Yahoo Pipes but it doesn't seem to be do anything at all.

Yahoo's documentation mentions capture groups are supported.

So you could likely use the String Regex module to e.g. replace ipsum (\w+) with $1.
