Sounds like a challenge....

... for perl golf? A little bit too easy, I think.

I wrote this on my first try

Nice, but it doesn't work when applied to the entire page (not just the fragment I posted). I see a lot of page fragments in the result. The IP is there, but burried in a lot of junk.

Only two lines, and still a no-brainer. ;-)

It seems you can write REs with just your muscle memory ... ;-) My brain is already in sleep mode, so I can see only line noise. I will look again tomorrow ...
