YDK netconf read fails when <data> tag has namespace prefix

[ghost]

Issue tracker is ONLY used for reporting bugs. Please use the YDK Community for any support issues.

Expected Behavior

data tag with namespace prefix should work

Current Behavior

Below reply from device causes ydk.errors.YServiceProviderError: Can't find data tag in reply sent by device error

<nc:rpc-reply xmlns:nc="urn:ietf:params:xml:ns:netconf:base:1.0" xmlns:junos="http://xml.juniper.net/junos/15.1X49/junos" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="1">
  <nc:data>
...
</nc:data>
</nc:rpc-reply>

[ghost]

Also fails if the rpc-reply for get or get-config contains <data> tag within another <data> tag

Opened IOS XR bug CSCvn36121 (Cisco-IOS-XR-bundlemgr-oper Yang model conflicts with IETF standard). The XR development team agreed and took it to work. Therefore closing this issue.

[ygorelik]

The tag within another tag issue has been fixed in YDK-0.8.1. See issue 851 for details
