Amazon (API) Web Services Script

I would like a simple tool that will query Amazons API and retrieve specific browsenode information. I am trying to accomplish the following. 1. Query a specific category and retrieve the top 100 results. 2. List the (one to three) sub categories/nodes each result is listed in. 3. List a total count for items within each category/node. i.e. Under E-books / Fiction the first and fifteenth results are: #1 Fifty Shades of Grey, #1 in Kindle Store > Kindle eBooks > Fiction > Genre Fiction > Romance > Contemporary, (24,004) #15 On the Island, #1 in Kindle eBooks > Fiction > Action & Adventure, (35,186) #2 in Kindle Store > Kindle eBooks > Fiction > Genre Fiction > Romance > Contemporary, (24,004) 4. Dump the data into a datasheet for analysis.
