sed: print out to first blank line
I am trying to use wget and sed to extract a text based weather forecast for the Greater Victoria area only, this is one paragraph of many in a web page. I have tried /^$/ but that does not seem to work. So far I get mostly what I want with this:
wget -qO -
http://www.weatheroffice.gc.ca/forecast/textforecast_e
.html?Bulletin=fpcn11.cwvr | sed -n "/Greater Victoria/,/Fraser/p
"
but that stops one line ahead of what I want by using /Fraser/ . How can I change the sed portion of above to stop at what appears to be a blank line in the text?

NAME

DESCRIPTION

of a Weather::Com::DayForecast object.
