blocked links in sitemap

i'm using a online sitemap generator tool which generates links even for which are blocked in robots.txt. Is these block开发者_StackOverflow社区ed links affect site ranking ? . Is there anyway to overcome it ?

If you have made a robots.txt file that blocks the pages, it shouldn't affect your ranking.

Have you tried emailing the developer of the sitemaps tool you use? Maybe they can help you, so the tool obeys your robots.txt file
