Assuming your XPath translation is accurate, it will return no data (response A). ________________________________ From: netmod <netmod-bounces@ietf.org> on behalf of Shiva Kumar Pathori <pathori@gmail.com> Sent: Tuesday, 22 May 2018 8:38 p.m. To: netmod@ietf.org Subject: [netmod] Clarification about subtree filtering Hi, Can somebody clarify what could be the response for the <get-config> operation provided below. Following is the user information in the datastore that is provided in the RFC 6241 as example. <rpc message-id="101" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0"> <get-config> <source> <running/> </source> <filter type="subtree"> <top xmlns="http://example.com/schema/1.2/config"> <users/> </top> </filter> </get-config> </rpc> <rpc-reply message-id="101" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0"> <data> <top xmlns="http://example.com/schema/1.2/config"> <users> <user> <name>root</name> <type>superuser</type> <full-name>Charlie Root</full-name> <company-info> <dept>1</dept> <id>1</id> </company-info> </user> <user> <name>fred</name> <type>admin</type> <full-name>Fred Flintstone</full-name> <company-info> <dept>2</dept> <id>2</id> </company-info> </user> <user> <name>barney</name> <type>admin</type> <full-name>Barney Rubble</full-name> <company-info> <dept>2</dept> <id>3</id> </company-info> </user> </users> </top> </data> </rpc-reply> The <get-config> operation with content-match at parent and child nodes; <rpc message-id="101" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0"> <get-config> <source> <running/> </source> <filter type="subtree"> <top xmlns="http://example.com/schema/1.2/config"> <users> <user> <type>admin</name> <company-info> <dept>1</dept> </company-info> </user> </users> </top> </filter> </get-config> </rpc> The equivalent XPATH expression : <rpc message-id="101" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0"> <get-config> <source> <running/> </source> <filter xmlns:t="http://example.com/schema/1.2/config" type="xpath" select="/t:top/t:users/t:user[t:type='admin']/t:company-info[t:dept='1']"/> </get-config> </rpc> For this what could be the response a) The response based on content-match nodes are AND-ed together <rpc-reply message-id="101" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0"> <data> </data> </rpc-reply> OR b) The response based on content-match nodes treated separately <rpc-reply message-id="101" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0"> <data> <top xmlns="http://example.com/schema/1.2/config"> <users> <user> <name>fred</name> <type>admin</type> <full-name>Fred Flintstone</full-name> </user> <user> <name>barney</name> <type>admin</type> <full-name>Barney Rubble</full-name> </user> </users> </top> </data> </rpc-reply> Regards, Shiva
