| Abstract: | The problem of processing streaming XML data is gaining widespread attention in the research community. XPath query predicate processing model is proposed to solve the issue of a large number of common predicates existing in mutable XPath query. In order to improve query processing performance, Stream Indexing technology is introduced. This article has provided baaie ideas of the model and model structure, and it is proved by experiment that this model can improve query efficiency effectively. |
