6608 amazon data API lookup

I would like to find the data from the URL in the attached file, look for file query.txt. But for a list of input ASIN's. Also, make your script read the ASIN's from a text file. Also, make it robust enough to handle a very large number of ASIN's (such as a several hundred thousand). The results should output into a MySQL database. I want to know all of the details in the offer summary for each ASIN. For the example of the XML output from Amazon, look at [login to view URL] in the attached file. I have some scripts that you can modify to make this work. The current scripts do not read in a lot of band names very well. It has timeout issues and you should overcome this. Also, the bands should come from an input text file, not from within the php file.
