R regular expression: http matching
===

I'm having problems using regular expression to match http links. I have a pattern that i would like to extract from a websites source code. The source code has 200+ lines with lots of HTML gibberish like `</html><body... useless links useless images'`

The http links that I need fall under this pattern:

    <a href"http:www.google.com/....1,1">
    <a href"http:www.google.com/....2,2">
    <a href"http:www.google.com/....3,3">

I just want to get the http links, and the unique pattern to them is the ending. Please help, I've been stuck for hours experimenting with gusb, regxpr and grep.
