                                      If the HTML is XHTML compliant you could treat it as XML and get the rows and values from the table using an xml document and
                                      the right set of xpath queries. This would be a fairly elegant way to do it and would probably require the least amount of code. If you
                                      can't expect the input to conform to XHTML then you'll have to write a parser to handle more poorly formed input.

                                      Hey Pete,
                                      Thanx fo ur reply. I achieved the application by parsing. I didn'y use XHTML. I used html text as string and then parsed it to generate
                                      the required criteria. Herez the code.
