Site Map XML files for google webmaster tools NEW UPDATE

[dodolzlegit]

shortly after I submit sitemap in google webmaster tools, they do not accept it.
message given as follows :

Code:

Paths don't match
We've detected that you submitted your Sitemap using a URL path that includes the www prefix (for instance, http://www.example.com/sitemap.xml). However, the URLs listed inside your Sitemap don't use the www prefix (for instance, http://example.com/myfile.htm)

please let me know how to be accepted my sitemap by google webmaster tools!

Thanks for your attention..
