We just bought a Wordpress design for our site, but quickly realized trying to publish our inventory is going to be rather difficult. Currently, we have our inventory going through Homenet but we wanted to create a more robust site that looked a little nicer--no offense Homenet 
So now we are stumped on what to do. The theme we purchased said it was easily able to update your inventory with "one click" and even their support said you would be able to update it quickly with an XML feed. However, it appears that the XML "feed" is rather a file that you manually have to update each time through the WP back end.
All of our inventory is in a CSV file and had a programmer create us something that transforms that into a XML feed with a URL, sort of like a sitemap but only with our inventory data.
ANY suggestions on what to do?
Thanks in advance
