java解析XML

废话不多说。

一个简单的解析xml，希望对某些朋友有所借鉴。

新建立一个web的工程，测试使用。

把这些jar包放入lib下

测试解析的xml如下：

<?xml version="1.0" encoding="utf-8"?><glass version="123"><work><job><id>job0001</id><workId>work0001</workId><name>GS01</name><type>abedo1</type><tag>mod09GA0</tag><rule><start>2000-1-1</start><timeUnit>year</timeUnit><timeLength>1</timeLength><stop>2005-12-32</stop></rule><rule><start>2006-1-1</start><timeUnit>month</timeUnit><timeLength>6</timeLength><stop>2009-12-31</stop></rule></job><job><id>job0002</id><workId>work0002</workId><name>GS02</name><type>abedo2</type><tag>mod09GA1</tag><rule><start>2000-1-1</start><timeUnit>year</timeUnit><timeLength>2</timeLength><stop>2005-12-32</stop></rule><rule><start>2006-1-1</start><timeUnit>month</timeUnit><timeLength>7</timeLength><stop>2009-12-31</stop></rule></job></work></glass>

建立一个解析需要的xsd

同时注意将namespace相关清除（如果规范由我们定  可以有namespace 但是这个生成的xml与规范中是不同的会加带namespace）

建立需要的Typs

xsd代码如下：

<?xml version="1.0" encoding="UTF-8"?><xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"><xsd:complexType name="glass"><xsd:sequence><xsd:element name="work" type="work"></xsd:element></xsd:sequence><xsd:attribute name="version" type="xsd:string"></xsd:attribute></xsd:complexType><xsd:complexType name="work"><xsd:sequence><xsd:element name="job" type="job"></xsd:element>    </xsd:sequence></xsd:complexType><xsd:complexType name="job"><xsd:sequence><xsd:element name="id" type="xsd:string"></xsd:element><xsd:element name="workId" type="xsd:string"></xsd:element><xsd:element name="name" type="xsd:string"></xsd:element><xsd:element name="type" type="xsd:string"></xsd:element><xsd:element name="tag" type="xsd:string"></xsd:element><xsd:element name="rule" type="rule"></xsd:element></xsd:sequence></xsd:complexType>    <xsd:complexType name="rule">    <xsd:sequence>    <xsd:element name="start" type="xsd:string"></xsd:element>    <xsd:element name="timeUnit" type="xsd:string"></xsd:element>    <xsd:element name="timeLength" type="xsd:string"></xsd:element>    <xsd:element name="stop" type="xsd:string"></xsd:element>    </xsd:sequence>    </xsd:complexType>    <xsd:element name="glass" type="glass"></xsd:element></xsd:schema>

把xsd拷贝到c:下一份

写好xsd文件后用xjc工具来帮助我们生成XSD对应的java映射类、点击运行选择当前的工程  同时注意那两个勾勾上然后点击serach

后输入xjc会看见XJCFacade 点击ok7

Ok 解析类生成成功！！！

主要生成的代码可能少根节点标记如果少了主要添加：
