filter in netconf - one specific entry

[shiraez]

my db:

<interfaces xmlns="urn:ietf:params:xml:ns:yang:ietf-interfaces">
   <interface>
      <name>interface-1</name>
      <type>ianaift:starLan</type>
      <enabled>true</enabled>
   </interface>
   <interface>
      <name>interface-2</name>
      <type>ianaift:starLan</type>
      <enabled>true</enabled>
   </interface>
</interfaces>

I try to filter the data with the procedure -(like the example in the link)

<rpc xmlns="urn:ietf:params:xml:ns:netconf:base:1.0"><get-config><source><running/></source><filter type="subtree"><interfaces xmlns="urn:ietf:params:xml:ns:yang:ietf-interfaces"><interface><name>interface-1</name></interface></interfaces></filter></get-config></rpc>]]>]]>

The reply was --

<rpc-reply xmlns="urn:ietf:params:xml:ns:netconf:base:1.0"><data><interfaces xmlns="urn:ietf:params:xml:ns:yang:ietf-interfaces"><interface><name>interface-1</name><type>ianaift:starLan</type><enabled>true</enabled></interface><interface><name>interface-2</name><type>ianaift:starLan</type><enabled>true</enabled></interface></interfaces></data></rpc-reply>

I expect to the reply

<rpc-reply xmlns="urn:ietf:params:xml:ns:netconf:base:1.0"><data><interfaces xmlns="urn:ietf:params:xml:ns:yang:ietf-interfaces"><interface><name>interface-1</name><type>ianaift:starLan</type><enabled>true</enabled></interface></interfaces></data></rpc-reply>

I did something wrong?

Yes, I recommend the use of filter type xpath capability (rfc 6241 sec 8.9). In this example, for example the following would work:

<rpc xmlns="urn:ietf:params:xml:ns:netconf:base:1.0"><get-config><source><candidate/></source><filter type="xpath" select="/if:interfaces/if:interface[if:name='1']" xmlns:if="urn:ietf:params:xml:ns:yang:ietf-interfaces"/></get-config></rpc>]]>]]>

That said, subtrees should also work, therefore I file this as a bug.

Should be fixed, but is slower than XPATH and does not support namespaces currently.
Please verify.
