The fields list is all you need. Copy the field list across the top row in a new Excel page. Then fill in the details underneath, for your your property. It will include items like real estate type (house, condo etc), for sale or rental, address, various description fields, and things such as DisloseAddress, which you fill with Yes if you want it done and No if you don’t want it. Any that don’t apply to your ad, just leave blank.

This lets you submit numerous properties on one XML sheet, one property per row on the sheet.

If you could come back here and put the link for the page that directs you to that PDF, I could look it up for you and give you better details.

I see what you mean.

Address type the address.

Other items where it days "decimal" just type numbers eg 56000.00 or 3.5, no commas or dollar signs.

"String" means words, eg name of provider (you) or builder.

for "Enumeration" they’ve listed all the choices you have. I get the impression you need to put these into quotes, the way they have them shown.

Woops, further down (purchase, lease, rent etc) they DON’T have them in quotes. Try them each way.

I suggest you copy only the compulsory fields to your spreadsheet, and submit ONE sample, with one item in quotes and one not. See which one comes out and then stick with that style for the rest.

listingsKey and ListingKey are confusingly NOT THE SAME. The top one is a code you invent eg "julylisting1" for the whole ad; the second is another one you invent for this particular property only, eg "wiscCondo".

"integer" means a number, eg 500 (square feet).

Anywhere that says "Boolean" means yes/no. They don’t specify whether to write Yes/no, so it might be better to use computer boolean, which is 1 for yes and 0 for no.

Where they ask for URLs, eg for images, put the images into Flickr and give the URL for that page.

Once you’ve worked out your test submission, also add in the next page of non-compulsory items, as some of them would be of good value to potential buyers.

Section 6 – Data Transmission tells you the address to upload your file to. I suggest you name your files with some initials, such as your company initials, and the date, eg MRL20100705.xml.

WOW they expect a lot of computer expertise from real estate experts. I hope this helps you get started.
