How to avoid create a directory "public"?

[bydeath]

I set a SetPublicPath to '/tmp', there are xml file in. Bug there is another directory named "public". So I also use SetSitemapsPath to '/tmp'. But the directory "public" is created. how to avoid create the "public " directory? And I don't need to upload the sitemap file to remote machine. I just need to generate the xml file locally.

The content of xml in "public" contain a sitemapindex tag

You must call Sitemap.Create after SetPublicPath / SetSitemapsPath.
