大家好,又见面了,我是你们的朋友全栈君。
Dom解析是将xml文件全部载入到内存,组装成一颗dom树,然后通过节点以及节点之间的关系来解析xml文件,与平台无关,java提供的一种基础的解析XML文件的API,理解较简单,但是由于整个文档都需要载入内存,不适用于文档较大时。
2.SAX方式解析XML
基于事件驱动,逐条解析,适用于只处理xml数据,不易编码,而且很难同时访问同一个文档中的多处不同数据
3.JDOM方式解析XML
简化与XML的交互并且比使用DOM实现更快,仅使用具体类而不使用接口因此简化了API,并且易于使用
4.DOM4j方式解析XML
JDOM的一种智能分支,功能较强大,建议熟练使用
下面给出例子:
