Amazon Product.XSD Requirements

= THIS PROJECT IS URGENT = Submitting a new product to Amazon (_POST_PRODUCT_DATA_) requires an XML element of <ProductData>, which is a rabbit-hole of XSD files and Browse Tree Guides (BTG) attributes. Users will select the category-specific XSD for their product (example: [login to view URL], or [login to view URL]) from our UI. That's where this project begins. Most of the XSD's have requirements such as ProductType and other elements; the settings of which set the requirement of additional elements and attributes. The goal of this project is to set the minimum requirements for the chosen XSD. Now back to the beginning. The user is on a UI form page containing inputs for the other data required for submitting their product to Amazon. 1) They select the XSD, an AJAX request is made to your script. 2) Your script returns dynamically generated form elements (inputs required by the XSD) for inclusion into the form. 3) When additional fields become required (based on the user's input), they too need to be dynamically included as necessary (or hidden by CSS until necessary). 4) Upon submission of the form, I will pass the post data to your PHP function to process and return a valid <ProductData> XML element for the chosen XSD. Primary XSD: [login to view URL] Most ProductType's have a BTG Excel file containing the category nodes and attributes. One for ProductType=ToysAndGames is attached for your review. Please review those documents before bidding. Thank you.
