I was simply pointing out that creating physically a folder for the target, then using a path rule they all show... I manually exclude the listing by not including in that folder.
Code:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<smartplaylist type="movies">
<name>Pixar</name>
<match>one</match>
<rule field="path" operator="contains">Pixar</rule>
<rule field="studio" operator="contains">Pixar</rule>
</smartplaylist>
My second suggestion would seem to work. The Country 'is not' rule is placed for each country you do not want in the list.... e.g. will eliminate China / U.S.A. or whatever country you don't want, yet include just China. You make a smart playlist for each (or combinations) country you want to collect, then tie them together with a master smart playlist. Although in this effort it might be easier to just use Kodi Tags.
This pulls only the country 'China' from the list, although in yours you may have to add more exclusions.
Code:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<smartplaylist type="movies">
<name>China - Asian</name>
<match>all</match>
<rule field="country" operator="is">
<value>China</value>
</rule>
<rule field="country" operator="isnot">
<value>France</value>
</rule>
<rule field="country" operator="isnot">
<value>USA</value>
</rule>
<rule field="country" operator="isnot">
<value>Canada</value>
</rule>
<rule field="country" operator="isnot">
<value>Japan</value>
</rule>
<rule field="country" operator="isnot">
<value>Hong Kong</value>
</rule>
<rule field="country" operator="isnot">
<value>Tiawan</value>
</rule>
<rule field="country" operator="isnot">
<value>Korea</value>
</rule>
<rule field="country" operator="isnot">
<value>Singapore</value>
</rule>
<rule field="country" operator="isnot">
<value>South Korea</value>
</rule>
</smartplaylist>
You would make another one for Japan etc... and then use a Master Smart Playlist to import the country playlists. Not a lot of effort with cut&paste editors.
