萨克斯解析器与字符串xml +畸形错误

我想从xml字符串中读取数据，并使用setter getter方法设置各自的标记元素，但我的xml在xml文件中显示畸形错误。我在这里做错了什么是我的代码。萨克斯解析器与字符串xml +畸形错误

这将按预期工作

     android:layout_height="wrap_content" 
     android:text="Parse XML Using SAX" /> 
</LinearLayout>

你可以看到在这两个logcat的和烤面包的输出。

使用xmlPullParser尝试不是Sax！像这样：

import java.io.IOException;

import java.io.StringReader;

import org.xmlpull.v1.XmlPullParser;

import org.xmlpull.v1.XmlPullParserException;

import org.xmlpull.v1.XmlPullParserFactory;

public class XmlPullParserCdb {

public static void parse(String dados) throws XmlPullParserException, IOException { 
    XmlPullParserFactory factory = XmlPullParserFactory.newInstance(); 
    factory.setNamespaceAware(true); 
    XmlPullParser xpp = factory.newPullParser(); 

    xpp.setInput(new StringReader(dados)); 
    int eventType = xpp.getEventType(); 
    while (eventType != XmlPullParser.END_DOCUMENT) { 
     if (eventType == XmlPullParser.START_DOCUMENT) { 
      System.out.println("Start document"); 
     } else if (eventType == XmlPullParser.END_DOCUMENT) { 
      System.out.println("End 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(); 
    } 
}

}
