I'm not looking for a sitemap, I'm looking to create an xml file that I can have a flash menu access, but I don't want to generate the XML file each time someone visits a page, I want to have a static XML to refer to for speed. And I'd like to have wordpress update the file whenever new content is posted(not comments).
Is there anything built into wordpress that would allow me to do this? Any plugins? Again, I don't want a sitemap. I want a specific list of items. Right now I've been using page templates with custom loops, but it takes to long to generate every time.
