Solve the following python programming problem given the following code:
def compare_xml(want, got) : 
    "Tries to do a 'xml-comparison' of want and got. Plain string
    comparison doesn't always work because, for example, attribute
    ordering should not be important. Comment nodes are not considered in the
    comparison.
