Path API should accept XML declaration in anyxml data nodes

[111pontes]

Currently, anyxml data nodes in the Path API do not accept XML strings with an XML declaration (e.g. <?xml version="1.0" ?>).

Hey, I'm having trouble reproducing the error. Can you point me to a specific test?

Something like the below can reproduce the issue:

from ydk.path import NetconfSession, Codec, Repository      
from ydk.types import EncodingFormat                  

ncc = NetconfSession(address='<hostname>' , username='<user>', password='<pass>', port=<port>)
c=Codec()

root=ncc.get_root_schema()

g=root.create_rpc('ietf-netconf:get')
g.get_input_node().create_datanode('filter','''<?xml version="1.0"?>
                                              <bgp xmlns="http://openconfig.net/yang/bgp"/>''')
g(ncc) # Fails here
