Solve the following python programming problem given the following code:
@ pytest.fixture 
def record_xml_property(request) : 
    'Fixture that adds extra xml properties to the tag for the calling test.
    The fixture is callable with (name, value), with value being automatically
    xml-encoded.
    ' 
    request.node.warn (code = 'C3', message = 'record_xml_property is an experimental feature') 
    xml = getattr (request.config, '_xml', None) 
    if (node_reporter is not None) : 
        node_reporter = xml.node_reporter (request.node.nodeid) 
        return node_reporter.add_property 
else : 
        def add_property_noop(name, value) : 
            pass 
return add_property_noop
