Is it possible to generate an xpath to a node using the Python API?

[Hubro]

Given a Maagic "Node" object, I need to automatically generate an xpath to it.

I know NSO can already do this, as it generates xpaths when running "show full-configuration foo bar | display xpath". Is there any way to do this using NSO's Python API?

I know I can get the keypath to the node using the "_path" attribute, but that value can't be saved in a leaf with the "instance-identifier" type, as it has to be an xpath.

You can use _ncs.xpath_pp_kpath for this.

That sounds ideal, but there is one issue: It requires a HKeypathRef object, but all I get from node._path is a string. Is there some way to convert a string to a HKeypathRef object, or can I get a HKeypathRef from a Maagic node somehow?

This is one way to get it, although I do think it is not quite elegant:

def maagic_node_to_xpath(maagic_node):
    with ncs.maapi.single_read_trans('admin', 'system') as m:
        m.cd(maagic_node._path)
        return _ncs.xpath_pp_kpath(m.getcwd_kpath())

"getcwd_kpath" returns the current position in maapi, as a HKeypathRef. So, you first 'cd' to the required path, then get it's HKeypathRef using which you get the XPath.

Is there any restconf equivalent call to get the service configs in xpath format?
