Hi, I had the same problem trying to export/import all contents from one site to a new one.
7zip the XML file didn’t work.
In the end I did:
– downloaded from the old site the wp-content\uploads directory to local disk
– uploaded the wp-content\uploads directory to the new site
– exported the content from the old site via WP “tool” + “export”
– edited the XML file and changed the http:\\oldsite.com in http:\\newsite.com
– imported the XML file via WP “tool” + “import” (WP run importer)
It works ??
Ah … Blogvault is a plugin but it is not for free …
