Abstract: Abstract Since XML parsing is time-consuming operation which greatly affects the performance of XML application,parallclization is an important optimization measure. Existing parsing methods need prcparsing stage to ensure proper data partition so as to complete XML segments parsing in parallel, however, pre-parsing tends to be long-running and Rdifficult to be optimized. This paper presented a schema which supports parallel suB-tree construction upon arbitrary XML segments. Sub-trees were merged to form whole XML tree in final stage. Experiment results indicate that our schema can efficiently realize parallel XML parsing in multi-core environment.

Key words: XML parsing, Sulrtrec construction, Parallel, Multi core
