I already generate my xml sitemap with drupal module "sitemap" now i wanted to show that sitemap inside a view.
It is possible to do this?
No, or at least not, with XML Sitemap & Views module. There is no Views integration with the XML Sitemap module. Given how both these modules work (a view being defined by base table & XML sitemap trying to generate a list of all indexable site paths), I think you'd be better off looking for another solution to embed all your site paths into the site.
