| 摘 要： | Webservices应用中存在大量在线XML文档处理的需求，利用现行的XML数据处理方法来处理上述在线文档是一项可行方案，在线文档的加载问题应运而生；目前对XML数据的存储和查询都是基于对XML文档树的某种编码方法，使用扩展编码方法以提高文档更新性能；如何基于扩展编码方法完成对在线文档加载的研究目前还比较少．提出一种新的扩展编码方法，在此编码的基础上，提出一种适合在线XML文档的加载方法，通过统计同模式的XML文档特征和更新特征，一遍解析文档完成扩展编码和加载；实验结果表明，加载效率和更新性能较好．

| Abstract: | Online XML data are frequently generated in application of Web services It is feasible to employ actual XML processing methods and techniques to process online XML Most of XML storage and query strategies are based on some numbering scheme, and it is necessary to use extended numbering scheme to sustain updating well However, few studies have been reported on the issue of loading for online XML documents based on extended numbering Proposed in this paper are a new numbering scheme and a loading algorithm for online XML documents The approach makes use of statistical information about character of loaded documents with the same schema in order to finish loading in one pass Experiments show the effectiveness of these algorithms |
