sed and grep are stream processors that operate line by line. To do
what you are interested in (grabbing information from multiple lines),
you'll probably find Perl to be a much more useful tool. It's regular
expression parser is also line oriented, but you can change the
definition of a "line" such that it can match and extract data from more
than one line at a time.
Once you start using Perl's regular expression syntax, you'll wonder how
you did without it.
