How to use $replace function to strip portion of url

[Cornerstone 0]

I am trying to set a table cell a from a facebook url, strip off the ?created and then combine the numeric portion of the url to a text string which becomes the rss feed for the page

 

http://www.facebook.com/pages/Something-Goes-Here/185929538088957?created

 

I am able to change the url to this

http://www.facebook.com/pages/Something-Goes-Here/185929538088957

 

I want to take this

185929538088957

 

and add this to the begining

http://www.facebook.com/feeds/page.php?format=atom10&id=

 

so it becomes this

http://www.facebook.com/feeds/page.php?format=atom10&id=185929538088957

 

 

Can anyone point me in the right direction

Thanks That definately puts me on the right track.

 

I do have a question though in the middle of the facebook url where the /Something-Goes-Here/

it will different each time but it should be the name of the page

http://www.facebook.com/pages/Something-Goes-Here/

 

I could probably used the technique you showed me to ad a - between the page name but is there a way use wild cards instead?

I don't think so. I will give that some thinking time. Maybe someone else in here will have an idea better than mine (many do!). I am a small cog in a much bigger wheel.
