Solve the following python programming problem given the following code:
def test_postprocessor_skip(self) : 
    def postprocessor(path, key, value) : 
        if (key == 'b') : 
            value = int (value) 
            if (value == 3) : 
                return None 
return (key, value) 
self.assertEqual ({ 
        'a' : { 
            'b' : [1, 2], 
}, 
}, parse ('<a><b>1</b><b>2</b><b>3</b></a>', postprocessor = self))
