There is no longer need for XML files. We have a built in demo content importer, directly in theme options on the General tab. And its even better than XML files because its imports everything, not just pages and posts. It gives you pages, posts, sliders, widgets, sidebars, theme options and more.
Check it out! And here is the info from our docs, http://theme-fusion.com/avada-doc/demo-content-info/import-xml-file/
