automated bulk phone number lookup

Simple project: I need a script/program to look up phonenumbers of a list with people I have (names/addresses), via online services like Yahoo! Search or White Pages. The technical problem here is that I do not know of any pages where you can already enter the address in the search formular. So the process would have to look like this: -Fill in the name, city and state, search. That could on some pages be done very easily because they include query strings in the URL, such as, for "John Smith, New York, NY": [login to view URL] -The problem is that for common names there might be lots of results, as in the above link. In that case there'd need to be an automated way to loop through the pages, see if you find any record with the matching address, if so, scrap the phone number, else, just leave the record empty. -Loop through a list of provided names/addresses (in any format that's convenient for your program, say .txt, .csv, .xlsx or whatever). -Save the output (the phone numbers that could successfully be found next to the matching names and addresses) in a new file.
