I've been trying to get to know the .xml file and the ad importer plugin. I am getting a handle on the file itself but I keep wondering how to get the spreadsheet to .xml working in some sensible way. The Mac version of Office/Excel 2011 is not able to export a working xml in developer mode as far as I see.
Many programs reed the xml file and I can make a working xml file but inserting the listing info listing by listing, attribute by attribute, can not be what the ad importer is for. I would really like to know some good suggestions for preferred software.
