Once you have the file made copy it and paste it into your file folder to ftp or upload to
the server within your site files. I stuck mine in with the individual page files in the root directory..
Now it's time to ask the search engine if they can see it. Here is the magic code to put into your browser.
To submit to Google use this address but be sure to replace "yoursite" with your own website's address including the /sitemap.xml.
If you put it in with the webpages, that would be the address.
For Bing (Microsoft Search engine)
These two submission of sitemap.xml sites from Google and Bing work fine!
For Yahoo (this has not worked lately - I am hoping that Yahoo will fix it)
Call up the addresses and you should get a response from those top two search engines.
