Why are you supposed to use a regex? A regex is very specifically the wrong tool for the job here. — chrylis -cautiouslyoptimistic-, May 05 '15 at 06:55
You should use an HTML parser, as regex is not the right tool to parse HTML. Anyway, have a look [here](https://developer.walmartlabs.com/), it's the walmart official developer page. Register, get your keys, and use their REST service. This way your application will download much less data and you won't need regexes/HTML parsers to do the job. — BackSlash, May 05 '15 at 07:00

If you can't use API's, you should use a framework for this. Take a look at http://jsoup.org

It will generate a strucutred document and allows you to iterate over ids, classes, tags and so on.

E.g.

findElementsByClass("sup"). I can provide some examplecode when I'm back at my desktop.
