| Abstract: | Xerces is the most popular and best performed parser till now. But its architecture is so complicated that it limits its performance. By optimizing lexical and syntax processing for XML, along with constructing the light-weighted architecture, an efficient XML parser- OnceSAXParser is implemented. The paper compares it with Xerces which is a most popular XML parser from the view of structure analysis and performance test. The results of performance tests are given to show that OnceSAXParser is 27% faster than Xerces on the average. |
