Regular Expressions in Visual Web Developer 2012

I have the following link that is one of 100 links on my web page.

<a onclick="window.open('http://www.link.com,'popup', 'width=800,height=600,resizable=yes,scrollbars=yes'); return false;" href="http://www.link.com">

I'd like to remove the onclick portion or (onclick="window.open('http://www.link.com,'popup', 'width=800,height=600,resizable=yes,scrollbars=yes'); return false;") for each link.  The problem is the link for each is different.  

Using regular expressions, how do I remove the portion above?  Thanks in advance!
