What format should my site-map be in?

I am creating a site-map with all urls on my site!

I have a classifieds site, so 开发者_如何学JAVAI'm using a mysql database.

What format should I create the 'static' page which contains all the urls and is 'auto incremented' for each ad created on my site ?

Thanks

Since you're creating a sitemap for google and not your users read this...

I'd checkout sitemaps.org for details of the format of the files.

You should create a dynamic page accessing your database and renbering the result in a html <ul> list
