After finding out that our current web service provider does not in fact provide an avenue to get a product feed to amazon I set out coding.
The main goal here is to produce a file that fits with Amazons upload template you can find here.
Problem and variables:
So the biggest problem I have to resolve is that key data I need to setup a listing through Amazon is not in one file. It’s in two, and of course those two files are of different types. One is a text file and the other an XML file. With all that being said I set off.
The first thing I needed to do was establish a common variable between both files. Something I can use to weave them both together with. In this case I used the Product ID code.
Second I need to parse each file differently exposing only the data I wish to use in the Amazon product feed. This proved relatively easy with the .XML file and slightly more cumbersome with the .txt file.
Great! Now I have parsed both files and am getting consistent good data. Each file has key identifier I can use to stitch them together when i wish however I have not yet constrained the data I want to see in the output.
Finally I create a file that acts as the master search file. In this file I have product sku’s delimited by new lines. This acts as the search mechanism for pulling the desired data out of the now already parsed data files.
And that’s it! The administrator adds the sku’s they desire to the search file and after a few seconds they receive neatly arranged output ready for upload to amazon. The administrator can either choose to add additional fields or send it up as is.
