Amazon Web Services & php

PHP app will query Amazon using Amazon Associates Web Service to collect all available BrowseNodes (starting with main nodes and getting their children all the way down). Each BrowseNode will be queried to get the MostGifted, MostWishedFor, and TopSellers. Each item will be queried to get the item title, price, manufacturer, ProductGroup, browsenode, whether it was MostGifted, MostWishedFor, or TopSellers, and a url direct to the individual item.? Duplicates are ok. This data will be written to a csv file and app can be run at any time to get updated data and a new file. ## Deliverables Application must read Amazon's? Web Service response as XML (not parse the string)
