I wrote the below code

    class TranslateParser(TokenParser, ):
        def top(self):
            value = self.value()
            if (value[0] == u"'"):
                m = re.match(u"^'([^']+)'(\\|.*$)", value)
                if m:
                    value = (u'"%s"%s' % (m.group(1).replace(u'"', u'\\"'), m.group(2)))
                elif (value[(-1)] == u"'"):
                    value = (u'"%s"' % value[1:(-1)].replace(u'"', u'\\"'))
            noop = False
            asvar = None
            message_context = None
            while self.more():
                tag = self.tag()
                if (tag == u'noop'):
                    noop = True
                elif (tag == u'context'):
                    message_context = parser.compile_filter(self.value())
                elif (tag == u'as'):
                    asvar = self.tag()
                else:
                    raise TemplateSyntaxError(u'Only    options    for    \'trans\'    are    \'noop\',    \'context    "xxx"\',    and    \'as    VAR\'.')
            return (value, noop, asvar, message_context)
    (value, noop, asvar, message_context) = TranslateParser(token.contents).top()
    return TranslateNode(parser.compile_filter(value), noop, asvar, message_context)
