android 怎么用XStream解析xml

时间:2022-06-25 23:04:00 编辑:袖梨 来源:一聚教程网

1,要解析的xml文件文件

xml="n" +
" n" +
"  1n" +
"  burnn" +
"  1.0n" +
"  n" +
"   10.5n" +
"   hhhhhhhhn" +
"  n" +
"  n" +
"   10.5n" +
"   hhhhhhhhn" +
"  n" +
" n" +
" n" +
"  2n" +
"  burn2n" +
"  2.1n" +
"  n" +
"   10.5n" +
"   hhhhhhhhn" +
"  n" +
"  n" +
"   10.5n" +
"   hhhhhhhhn" +
"  n" +
" n" +
" n" +
"  3n" +
"  burn3n" +
"  3.2n" +
"  n" +
"   10.5n" +
"   hhhhhhhhn" +
"  n" +
"  n" +
"   10.5n" +
"   hhhhhhhhn" +
"  n" +
" n" +
"";

2,新建xml文件对应的封装类

/**
* 
xml数据对应的封装类(注意实体类和xml数据的对应关系,所有标签都得对应)
*/
@XStreamAlias("apps")//配置标签别名
public class AppBean {


@XStreamImplicit//忽略集合根节点
private List app_list;


//必须有无参构造方法
public AppBean() {
}


public AppBean(List app_list) {
this.app_list = app_list;
}


public List getApp_list() {
return app_list;
}


public void setApp_list(List app_list) {
this.app_list = app_list;
}


@XStreamAlias("app")
public static class App{


private long id;
private String name;
private String version;


@XStreamImplicit
private List infor_list;


public App() {
}


public App(long id, List infor_list, String name, String version) {
this.id = id;
this.infor_list = infor_list;
this.name = name;
this.version = version;
}


public long getId() {
return id;
}


public void setId(long id) {
this.id = id;
}


public List getInfor_list() {
return infor_list;
}


public void setInfor_list(List infor_list) {
this.infor_list = infor_list;
}


public String getName() {
return name;
}


public void setName(String name) {
this.name = name;
}


public String getVersion() {
return version;
}


public void setVersion(String version) {
this.version = version;
}


@XStreamAlias("info")
public static class Infor{


private String message;
private double size;


public Infor() {
}


public Infor(String message, double size) {
this.message = message;
this.size = size;
}


public String getMessage() {
return message;
}


public void setMessage(String message) {
this.message = message;
}


public double getSize() {
return size;
}


public void setSize(double size) {
this.size = size;
}
}
}
}

3,开始xml解析

XStream xStream=new XStream();
xStream.processAnnotations(AppBean.class);//声明使用注解的类
AppBean ab2= (AppBean) xStream.fromXML(xml);//xml-->Bean,只能解析为对象,不能解析为集合
String xml=xStream.toXML(AppBean.class)//Bean-->xml
