Problems with xml import export to extract WP site into another WP site....
Context : extraction by export 432 posts to another new wp site... but during xml import only the first 82 posts were imported...
Diagnostic after many tests :
The lastest 82th post contain empty tag (a tag without term) described in xml as here.
<category domain="tag"><![CDATA]></category> <category domain="tag" nicename="53"><![CDATA]></category>
The solution :
before exporting : go in the admin tags menu and delete unexpected tags !
and now the xml produced file will be clean and work well.
Hope that help you !
Note: during the tests, some limits of export / import appear - but it is not the topic of this post.
