I have used web queries before but never tried to do anything like
this...

I have a spreadsheet with a column of URL's. What I would like to do
is write a macro that can loop through the "URL" column and query each
website for the contents of the meta description tag and store that in
an adjacent cell.

i.e. A site with the tag: <META NAME="Description" CONTENT="Website
Description ." would return the text "Website Description"

I don't even know where to start...
