You shouldn't write anything, you should use Browse to find it on your computer and import it from there. If you really want to import it from your server, then you may have to do a full path, ie. /home/sitename/public_html/includes/rest/of/path/to/xml/file (Typically, xml files in the /xml folder are not supposed to be uploaded as a product. They are usually files for the admin cp.)
