How to exclude posts from my sitemap,xml?

Hello,

I have installed the plug-in xml sitemap. My website name is http://www.ainfosolutions.com but when i run http://www.ainfosolutions.com/sitemap.xml — I can see unnecessary links coming from my post.

Can you please let me know how can i exclude my posts from sitemap.xml? I just want to crawl page links only.

Cheers!
Ashesh.
