Ok, I give up. How do you use sed to do a multiline search given a
regular expression? I don't want to replace anything, just do a
search, much like grep. However, I'm to understand that grep only
searches one line at a time.

Thanks, - Dave

after reading that, you'll might think of switching to another tool.

Do you have a suggestion, or even an example, or something else that
can match multi-lines given a regular expression? - Dave

awk. Post some small but realistic sample input, what you want to match on, and
the expected output.

I'd use Perl. The real reason to use Perl is that it has excellent
HTML/XHTML parsing modules ready to use. Other threads suggest that
HTML is the reason you are asking. If you think you can get by with a
text match rather than a real parse then other text tools can be used.

Another route worth considering is an XSLT processing tool.
