摘　　要：嵌入式Web服务能充分利用Web服务技术实现异构平台的数据交互和应用集成,xml解析是Web服务中重要一环,设计一款Sax方式的轻量级C语言xml解析器EmbedSax,以事件为驱动,借助树节点信息,准确高效地从xml文档中提取Web服务兴趣内容和生成xml,并在嵌入式平台上实现和验证。实验结果表明,在同等解析条件下与常用Sax解析器相比具有更高解析效率,可为资源受限平台Web服务和xml解析技术应用提供一定参考。Embedded Web Service can make full use of web service technology to realize data interaction and application integration on heterogeneous platforms.XML parsing is an important part of web service.Design a lightweight C language XML event-driven parser EmbedSax in Sax mode.With tree node information,It extracts the content of interest from the XML document and generates xml accurately and efficiently,then implements and verifies on the embedded platform.The experimental results show that under the same parsing conditions,it has higher parsing efficiency than the common Sax parsers,and can provide some reference for the application of resource-constrained platform web services and XML parsing technology.
