I need to extract from the pages of a single website of the data for well-specified TAG. The structure of the pages and fields to be extracted is always the same. The pages are all connected with each other as a directory and processing can be performed locally once downloaded the site with wget for example. The fields, about 3 or 4, then go into a MySQL database. Two of these fields will be "company name" and "e-mail address". Finally a simple script, preferably in php, should send an e-mail to each of these addresses.
