Abstract: Based on the exploration of current research of XSLT acceleration,a new method to transform XML data in parallel mode based on XSLT Stylesheet partitioning was proposed.The related topics were discussed including:1)how to obtain the independent transform units which can be executed concurrently without affecting each other,2)what is the proper number of parallel tasks according to the underlying platform being used and how to balance their workload,3)how to merge the individual intermediate results correctly.The proposed method was applied into the real project,i.e. the Open XML-UOF document format translation project,achieving fairly good result.This research is significant to the improvement of XML transform performance under parallel processing environment.
