android实现xml数据的解析

<? version="1.0" encoding="utf-8"?>

<Family>

<Father name="jin" age="34"></Father>

<Mother name="man" age="32"></Mother>

<Son name="xian" age="18"></Son>

</Family>

尖括号里的“Family”,"Father","Mother","Son"是属于标签（tag）

而“name”，“age”的是各个表签对应的属性

 DocumentBuilderFactory factory=DocumentBuilderFactory.newInstance();

 

 try {

  DocumentBuilder builder=factory.newDocumentBuilder();

//这个方法里面可以传入一个xml格式的字符串，也可以是文件 

  org.w3c.dom.Document document=builder.parse(getAssets().open("family.xml"));

  //获取根元素

     org.w3c.dom.Element e= document.getDocumentElement();

   

  //NodeList list=e.getElementsByTagName("Family");

 

 

 

  String totalString="";

 

 

   

   NodeList element=e.getElementsByTagName("Father");

 

   String attributeString =((org.w3c.dom.Element)element.item(0)).getAttribute("name");

   String ageString=((org.w3c.dom.Element)element.item(0)).getAttribute("age");

   totalString+=attributeString+":"+ageString+"\n";

   

   

   element=e.getElementsByTagName("Mother");

   

    attributeString =((org.w3c.dom.Element)element.item(0)).getAttribute("name");

    ageString=((org.w3c.dom.Element)element.item(0)).getAttribute("age");

   totalString+=attributeString+":"+ageString+"\n";

   

   

   

    element=e.getElementsByTagName("Son");

   

    attributeString =((org.w3c.dom.Element)element.item(0)).getAttribute("name");

    ageString=((org.w3c.dom.Element)element.item(0)).getAttribute("age");

   totalString+=attributeString+":"+ageString+"\n";
