namespace missing in exception messages for XML documents

[kwatsen]

[This is happening in my fork. I haven't tested against yangson/master yet]

The path provided in an error message from SchemaNode.from_raw() with an input document that has an unexpected leaf node:

    /ietf-sztp-bootstrap-server:input/foo-bar

The path provided in an error message from SchemaNode.from_xml() with an input document that has an unexpected leaf node:

    /input/foo-bar

The XML code should provide the namespaces in the same way. This may be related to the more general issue about how the XML code is inconsistent with how namespaces are represented in the ET structures: sometimes the namespace is in the attrib and sometime it's mangled into the tag.

In case there's any question, this is still an open issue.

My project has a unit test that accommodates the unexpected exception message. I'll know this issue is fixed when that unit test starts failing...

I don't know if this is the same issue, but I can feed this into from_raw:

{
    "ietf-hardware:hardware": {
        "component" : [{
            "name": "my-name",
            "class": "o-ran-hardware:O-DU-COMPONENT",
            "o-ran-hardware:o-ran-name": "my-oran-name"
        }]
    }
}

and it is happy, but it fails if I feed the equivalent into from_xml:

<data xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
  <hardware xmlns="urn:ietf:params:xml:ns:yang:ietf-hardware">
    <component>
      <name>my-name</name>
      <class xmlns:o-ran-hw="urn:o-ran:hardware:1.0">o-ran-hw:O-DU-COMPONENT</class>
      <o-ran-name xmlns="urn:o-ran:hardware:1.0">my-oran-name</o-ran-name>
    </component>
  </hardware>
</data>

It fails with a namespace missing exception on class, which is an identyRef,.

I can send you o-ran-hardware@2023-08-14.yang, though it won't accept it here. (It is publicly available on the internet)

In addition, on any system running netopeer2, if you do a netconf get with a subtree filter of either of these two:

<yang-library xmlns="urn:ietf:params:xml:ns:yang:ietf-yang-library"/>

or

<sysrepo-state xmlns="http://www.sysrepo.org/yang/sysrepo-monitoring"/>

then the form_xml on the result will always fail.
