I looked over you XPath article. Thanks.
But given the table structure noted above, will XPath actually work to
take the variables that I need in each of the columns and insert those
into database fields? I need to locate 3 separate columns and grab each
of those by row and insert those into a table. So the html and the
database table will end up looking the same.
Thanks.
