The SAX DOM just to overcome the shortcomings, analysis can begin immediately rather than waiting for all data are processed. And, because the application reads the data only at the check data, so no data is stored in memory, this is for large documents is a huge advantage. In fact, the application even without parsing the entire document; it can stop when a condition is met resolve.
