A simple query function

A simple query function I need to query the inventory of the website Homedepot ([login to view URL]). It needs to implement the function: When I bulk import a unique identifier (may be "UPC" is better, you can view the source code to find which elements are best), I can check the status of goods. (Put the unique identifier in the text or excel file) P.S. The goods of Homedepot can Ship to Home or Pick Up In Store, for me, the most important is that the product can Ship to Home. In general, when the product is not Ship to Home will be two situations: 1. Out of stock For example: http: //[login to view URL] 2. It can only be Pick Up In Store For example: http: //[login to view URL] So please help me write this simple program, it should have a good interface and can handle large amounts of data, which I can easily query a large number of product inventory status. Thanks!
