How do i force links other than www.mysite.com to open in a new window

[Cugel]

Suppose I have a page like this :

Blalbalbalbalablbalbalbalba
<a href='http://www.google.com/intl/xx-klingon/'>Google</a>
Blalbalbalbalablbalbalbalba
<a href='www.turbo10.com'>Turbo10</a>
BLalbalbalbalbalablbalbalabl
<a href='www.mysite.com?page=test&lang=en'>My site</a>

If i display this page in my browser, I want all the links, other than the links which are pointing to mysite.com, to open in a new window

I tried something several regular experssions, but can't figure it out.

Thanks for all the help !

Geez, after a couple of hours...

Anyway, here's my solution :

$strContent = preg_replace("/<a href=\"(http|ftp|https):\/\/(?!www.mysite.com)(.)\">/i","<a href=\"\1://\2\" target=\"_blank\">",$strContent);

Maybe it's helpfull for others
