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！！！
