It is available only in C++ code, where class <A href="https://github.com/CiscoDevNet/ydk-gen/blob/3edee4610648c3229dbd8f4c51ad7070c2b34f92/sdk/cpp/core/src/path/path_private.hpp#L94" target="_self"><EM>SchemaNodeImpl</EM></A> holds pointer to Libyang structure <A href="https://netopeer.liberouter.org/doc/libyang/master/group__schematree.html#structlys__node" target="_self"><EM>lys_node</EM></A>, which contains all the information about correspondent YANG model node. New development is required to expose that information in Python code. I suggest to open enhancement request for this new development on <A href="https://github.com/CiscoDevNet/ydk-gen/issues" target="_self">ydk-gen</A> GitHub.</P> Tue, 07 Jul 2020 02:42:47 GMT https://community.cisco.com/t5/tools/how-to-retrieve-substatements-using-path-api/m-p/4114315#M1825 yangorelik 2020-07-07T02:42:47Z
