How to find <tag> to </tag> HTML strings and 'save' them?

[mark at agtechnical.co.uk]

Hi All,

Apologies for the newbie question but I've searched and tried all
sorts for a few days and I'm pulling my hair out ;[

I have a 'reference' HTML file and a 'test' HTML file from which I
need to pull 10 strings, all of which are contained within <h2> tags,
e.g.:
<h2 class=r><a href="http://www.someplace.com/">Go Someplace</a></h2>

Once I've found the 10 I'd like to write them to another 'results'
html file. Perhaps a 'reference results' and a 'test results' file.
>From where I would then like to 'diff' the results to see if they
match.

Here's the rub: I cannot find a way to pull those 10 strings so I can
save them to the results pages.
Can anyone please suggest how this can be done?

I've tried allsorts but I've been learning Python for 1 week and just
don't know enough to mod example scripts it seems. don't even get me
started on python docs.. ayaa ;] Please feel free to teach me to suck
eggs because it's all new to me :)

Thanks in advance,

Mark.
