Hi,

I was wondering if there is any way I could extract domain names from the body of email messages in python. I was thinking of using regular expressions, but I am not too great in writing them, and was wondering if someone could help me out. Here's a sample email body:

<tr><td colspan="5"><font face="verdana" size="4" color="#999999"><b>Resource Links - </b></font><span class="snv"><a href="http://clk.about.com/?zi=4/RZ">Get Listed Here</a></span></td><td class="snv" valign="bottom" align="right"><a href="http://sprinks.about.com/faq/index.htm">What Is This?</a></td></tr><tr><td colspan="6" bgcolor="#999999"><img height="1" width="1"></td></tr><tr><td colspan="6"><map name="sgmap"><area href="http://x.about.com/sg/r/3412.htm?p=0&amp;ref=fooddrinksl_sg" shape="rect" coords="0, 0, 600, 20"><area href="http://x.about.com/sg/r/3412.htm?p=1&amp;ref=fooddrinksl_sg" shape="rect" coords="0, 55, 600, 75"><area href="http://x.about.com/sg/r/3412.htm?p=2&amp;ref=fooddrinksl_sg" shape="rect" coords="0, 110, 600, 130"></map><img border="0" src="http://z.about.com/sg/sg.gif?cuni=3412" usemap="#sgmap" width="600" height="160"></td></tr><tr><td colspan="6">&nbsp;</td></tr>
<tr><td colspan="6"><a name="d"><font face="verdana" size="4" color="#cc0000"><b>Top Picks - </b></font></a><a href="http://slclk.about.com/?zi=1/BAO" class="srvb">Fun Gift Ideas</a><span class="snv">
 from your <a href="http://chinesefood.about.com">Chinese Cuisine</a> Guide</span></td></tr><tr><td colspan="6" bgcolor="cc0000"><img height="1" width="1"></td></tr><tr><td colspan="6" class="snv">

So I would need "clk.about.com" etc.

Thanks!
