\ and \ operations ignore filter_criteria, when it contains a empty XML element. In instance, the following filter is ignored:
${filter} = Parse XML <interfaces xmlns="urn:ietf:params:xml:ns:yang:ietf-interfaces" />
${data} = Get alias=NE1 filter_criteria=${filter}
It should be possible to filter on a container element at the top in order to retreive the subtree. In instance: it should be possible to filter on \ (RFC8343) to retreive the /interfaces subtree).
Additionaly, empty filter is not an error, according to section 6.4.2. Empty Filter of RFC 6241.
To retreive the subtree, it's possible to include the (singular).
${filter} = Parse XML <interfaces xmlns="urn:ietf:params:xml:ns:yang:ietf-interfaces"><interface /></interfaces>
This is possible since the container element containts a list of elements.
This is not possible with ietf-system, where the container contains several leaf elements.
Patch suggestion
Line 190 for the def get_config() method and line 380 for def get() method.
I suggest to change if filter_criteria: to if filter_criteria is not None:.
