XML解析之JAXP

XML解析方式

DOM

Document Object Model，文档对象模型。这种方式是W3C推荐的处理XML的一种方式。
Dom解析将XML文件全部读入并生成DOM树，所有的XML标签，属性和文本内容均为DOM树上的节点，并采用节点操作的方式可以对任意一个元素进行增删改查。

SAX

Simple API for XML。这种方式不是官方标准，属于开源社区XML-DEV，几乎所有的XML解析器都支持它。
SAX解析是基于事件驱动的XML解析方式，该方式的工作需要依赖事件处理接口，根据发生的事件的发生来针对性的采取对应操作。由于该方式产生操作不需要加载全部XML文件，所以对于超大的XML文件的解析效率较高。

XML解析开发包

JAXP：是SUN公司推出的解析标准实现。
Dom4J：是开源组织推出的一种解析开发包，较为常用。
JDom：是开源组织推出的一种解析开发包。

JAXP

概述

JAXP（Java API for XML Processing）开发包是JavaSE的一部分，它由以下几个包及其子包组成：
org.w3c.dom：提供DOM方式解析XML的标准接口。
org.xml.sax：提供SAX方式解析XML的标准接口。
javax.xml：提供了解析XML文档的类。
javax.xml.parsers：提供了对XML文档解析工厂类，通过工厂类（DocumentBuilderFactory、SAXParserFactory）可以得到对XML文档进行解析的DOM和SAX解析器对象。

使用DOM方式解析XML文档

1. 常用API

解析器工厂类：DocumentBuilderFactory
解析器：DocumentBuilder
文档对象：Document
节点对象：Node
节点集合：NodeList
元素：Element
修改文件工厂类：TransformerFactory
保存文件：Transformer

2. 解析XML获取文档对象

使用SAX方式解析XML文档

1. 常用API

SAX解析器工厂类：SAXParserFactory
SAX解析器：SAXParser
XML读取类：XMLReader
事件处理接口：ContentHandler
默认事件处理适配器类：DefaultHandler

2. 获取SAX解析并设置事件处理器

注意：必须先设置时间处理器，后设置XML文件源
