The problem here is that your XML uses a namespace. I'm not very
familiar with xpaths either, but after a little googling I came up with
this:
- name: Reading RESTconf release
xml:
attribute: rel
content: attribute
path: "{{ api_root_filename }}"
xpath: "/*[name()='XRD']/*[name()='Link']"
register: return_restconf_release
- name: Showing attribute value
debug:
var:
return_restconf_release.matches[0]['{http://docs.oasis-open.org/ns/xri/xrd-1.0}Link']
This gives for me:
ok: [localhost] => {
"failed": false,
"return_restconf_release.matches[0]['{http://docs.oasis-open.org/ns/xri/xrd-1.0}Link']":
{
"href": "/restconf",
"rel": "restconf"
}
}
Cheers,
Felix
