Project Description:
I use Interspire Shopping cart 6. I need to export store products to xml with specific fields, in order to meet specifications of xml feed file of a price comparison site. Interspire, even with custom template from tools section, does not include a product link, and this is my biggest problem. Here is (unfortunately in Greek) the specifications of the xml file they ask to include my store to their catalog : . I hope you can translate with Google in English (it's easier)
An example of xml that I need is:
<?xml version="1.0" encoding="UTF-8"?>
