我使用DOM paarsing但得到学校的节点列表后，我unnable让其他atrribute一组这样的属性到coreesponding类请任何人指导我。我allready搜索谷歌和完成的例子，但不能得到任何线索。

Answer 1

看看XmlPullParser

从文档

public class SimpleXmlPullApp {

public static void main (String args[]) 
    throws XmlPullParserException, IOException 
{ 

    XmlPullParserFactory factory = XmlPullParserFactory.newInstance(); 
    factory.setNamespaceAware(true); 
    XmlPullParser xpp = factory.newPullParser(); 
    xpp.setInput(new StringReader ("<foo>Hello World!</foo>")); 
    int eventType = xpp.getEventType(); 
    while (eventType != XmlPullParser.END_DOCUMENT) { 
     if(eventType == XmlPullParser.START_DOCUMENT) { 
      System.out.println("Start document"); 
     } else if(eventType == XmlPullParser.START_TAG) { 
      System.out.println("Start tag "+xpp.getName()); 
     } else if(eventType == XmlPullParser.END_TAG) { 
      System.out.println("End tag "+xpp.getName()); 
     } else if(eventType == XmlPullParser.TEXT) { 
      System.out.println("Text "+xpp.getText()); 
     } 
     eventType = xpp.next(); 
    } 
    System.out.println("End document"); 
    } 

}

XML自然和正常允许嵌套的标签，其实，这就是为什么它是如此有用的部分。

Answer 2

你是什么意思的学校节点列表？你能指定你有问题的标签吗？

你可以这样获得的属性值：

t.getAttribute("<attributename>"); 

其中t为类型元素的对象。

假设你有屏幕元素，那么你可以这样做

NodeList Nl = Screen.getElementsByTagName("tab-bar-item"); 
    if(Nl!=null && Nl.size()>0){ 
     for(int i=0;i<Nl.size();i++){ 
     Element tab_bar_item = (Element) NL.item(i); 
     String title = tab_bar_item.getAttribute("title"); 
     /*you can get other attributes in the same way*/ 
     } 
    } 

希望帮助

嗨队友使用此代码获取标签栏：

XmlDocument doc1= new XmlDocument(); 
DataSet dsAPDP = new DataSet(); 
DataTable dtAPDP = new DataTable(); 
    using (XmlReader reader = new XmlNodeReader(doc1.DocumentElement)) 
    { 
     dsAPDP.ReadXml(reader); reader.Close(); 
    } 
dtAPDP = dsAPDP.Tables[0]; 

它将返回数据集。
