Thanks yazu...if you get a moment, could you explain a few things to me:
I understand what the sed command does, though not all of the syntax. From the man page: s/regexp/replacement. Why the ^ (was wondering about this character in the egrep command in the original script) and the $/ (is that the new line character)? And the third / indicates replace with a blank line since no other character is shown?

All of this is piped into the perl script.

Again, from the man page -00 will 'slurp' the stream in paragraph mode. -ne starts a while <> loop command. Not sure about perl command itself. Why the first /? The command searches for a tag:, but not sure what \s+(.*?) does, along with .* in the between tag searches. Not sure what /ns does, along with what the $1 and $2 refer to in the print line.

And I assume all of this can just be > into an output file, or is there a better way to do that with perl?

Thanks again!
