Well I just tried it and it worked like a charm. My next thing is to 
limit what it brings back.

Example
<h3>blah blah blah 7.0.0.3.4 blah blah blah</h3>

I want to pull just the 7.0.0.3.4 and none of the words. I am sure this 
is going to have to deal with more regular expressions but I never 
really understood how to use them well.
