/* if you want to parse a string, you need to create a RDFParser object with no parameter, if the triple has prefix, you also need to provide it.
* the whole string must be processed in one time of invoking parseString, pay attention to the triples in the string won't exceed the limit of RDFParser::TRIPLE_NUM_PER_GROUP.
