Robotframework: Get test case metrics like test name, test status, duration by parsing output.xml using robot.result package (api)

robotframework_test_case_metrics.py

from robot.api import ExecutionResult,ResultVisitor

class TestMetrics(ResultVisitor):

    def visit_test(self,test):
        print "Test Name: " + str(test.name) 
        print "Test Status: " + str(test.status)
        print "Test Starttime: " + str(test.starttime)
        print "Test Endtime: " + " " + str(test.endtime)
        print "Test Elapsedtime (Sec): " + " " + str(test.elapsedtime/float(1000))

result = ExecutionResult('output.xml')
result.configure(stat_config={'suite_stat_level': 2,
                              'tag_stat_combine': 'tagANDanother'})
result.visit(TestMetrics())

How to get the value out from visit_test ?
