If that's all you want to change, then you can just add the '?' (minimal
match) qualifier to the '.*' within your regexp. By default, the '*'
operator is "greedy" (that is, matches as much data as possible). If you
replace that with '.*?' it will find the minimum amount of text that
satisfies your requirements.
If you want heavier-duty HTML parsing, you're probably better of looking
for a library rather than trying to do it all by hand anyway, as the
other poster suggested.
