CentOS - Jun 2011 - regex question

Hey guys,
I am trying to extract a pattern from a downloaded html file. I only want the
first match
printed, problem is I don't know how to force sed to exit after printing the
first match of
a capture group. Anyone know the trick to manipulating {p;q;} to print a capture
group?

Thanks,
jlc

awk '{if ( $0 ~ /p;q;/ ) { print $0; exit;}}' filename

would work....

       mark "if Larry Wall could push perl in comp.lang.awk,
               I can answer a sed question this way...."

Dunno but Google 'sed only first match' gives some answers...
