Sitemap missing site address/domain in page URL's


I have generated my sitemap using smartcrawl.

How do I :
- hide category/tag pages incuded in sitemap
- add domain ( to URLs

When I try to submit to google webmaster tools I get,
Errors - Invalid URL, This is not a valid URL. Please correct it and resubmit.

The above error refers to urls like this

URL: /news/why-love-matters
Parent tag: url
Tag: loc

Please advise on best action,
