Solve the following python programming problem given the following code:
def _upload_xform(self, path, file_name) : 
    class PublishXForm (object) : 
        def __init__(self, xml_file, user) : 
            self.xml_file = xml_file 
            self.user = user 
def publish_xform(self) : 
            return publish_xml_form (self.xml_file, self.user) 
xml_file = default_storage.open (self) 
    xml_file.name = file_name 
    k = PublishXForm (xml_file, self.user) 
    return publish_form (k.publish_xform) 

    
    

    Fix the buggy line: xml_file = default_storage.open (self)
