[PHP] GET HEADLINES FROM ANOTHER SITE

[The New Source]

IŽd like to know how to get certain headlines from another site. I already got the 
permission from the site owner, but I'm short on the programing. It would be something 
like, get the source code from the url: www.url.com and then remove all the html, and 
get only the part that I need. Does anybody can give a hand?
Thanx,
Rodrigo.
