Parameters:

key (str or int): Path in Plex to fetch items from. If an int is passed

in, the key will be translated to /library/metadata/<key>. This allows

fetching an item only knowing its key-id.
|

cls (:class:`~plexapi.base.PlexObject`): If you know the class of the

items to be fetched, passing this in will help the parser ensure

it only returns those items. By default we convert the xml elements
|
||
with the best guess PlexObjects based on tag and type attrs.
|
||
etag (str): Only fetch items with the specified tag.
|
||
**kwargs (dict): Optionally add attribute filters on the items to fetch. For
|
||
example, passing in viewCount=0 will only return matching items. Filtering
|
||
is done before the Python objects are built to help keep things speedy.
|
||
Note: Because some attribute names are already used as arguments to this
|
||
function, such as 'tag', you may still reference the attr tag byappending
|
||
an underscore. For example, passing in _tag='foobar' will return all items
|
||
where tag='foobar'. Also Note: Case very much matters when specifying kwargs
|
||
-- Optionally, operators can be specified by append it
|
||
to the end of the attribute name for more complex lookups. For example,
|
||
passing in viewCount__gte=0 will return all items where viewCount >= 0.
|
||
Available operations include:
|
||
|
||
* __contains: Value contains specified arg.
|
||
* __endswith: Value ends with specified arg.
|
||
* __exact: Value matches specified arg.
|
||
* __exists (bool): Value is or is not present in the attrs.

* __iexact: Case insensative value matches specified arg.
