blackberry - Ksoap 解析查询

Question

我能够使用 ksoap2 获取复杂的类响应，现在我得到的响应是 xml 形式

任何人都可以帮我解决如何解析这个 Ksoap 响应吗？我已经在论坛上阅读了为它添加映射的内容，我也添加了映射。我可以使用 XML 解析技术来解析它吗？请为我提供一个合适的方法。谢谢

使用这个xml解析代码并解析:

public class xmlparsing extends UiApplication implements ListFieldCallback, FieldChangeListener 
{

public static void main(String[] args)
{
xmlparsing app = new xmlparsing();
app.enterEventDispatcher();
}


public long mycolor ;
Connection _connectionthread; 
private static ListField _list;
private static Vector listElements = new Vector();
public MainScreen screen = new MainScreen();
VerticalFieldManager mainManager;
VerticalFieldManager subManager;



public xmlparsing() 
{ 
super();
pushScreen(screen);

final Bitmap backgroundBitmap = Bitmap.getBitmapResource("blackbackground.png");

mainManager = new VerticalFieldManager(Manager.NO_VERTICAL_SCROLL ,Manager.NO_VERTICAL_SCROLLBAR )
{

public void paint(Graphics graphics)
{
graphics.drawBitmap(0, 0, Display.getWidth(),Display.getHeight(),backgroundBitmap, 0, 0);

super.paint(graphics);
}

};

subManager = new VerticalFieldManager(Manager.VERTICAL_SCROLL | Manager.VERTICAL_SCROLLBAR )
{
protected void sublayout( int maxWidth, int maxHeight )
{
int displayWidth = Display.getWidth();
int displayHeight = Display.getHeight();

super.sublayout( displayWidth, displayHeight);
setExtent( displayWidth, displayHeight);
}
}; 


screen.add(mainManager);

_list = new ListField()

{

public void paint(Graphics graphics)

{
graphics.setColor((int) mycolor);
super.paint(graphics);

}

};
mycolor = 0x00FFFFFF;
_list.invalidate();
_list.setEmptyString("* Feeds Not Available *", DrawStyle.HCENTER);
_list.setRowHeight(50);
_list.setCallback(this);
mainManager.add(subManager); 
listElements.removeAllElements();
_connectionthread = new Connection(); 
_connectionthread.start();
}


protected boolean navigationClick(int status, int time)
{
try
{
//navigate here to another screen if you need. 
}
catch(Exception e)
{
System.out.println("Exception:- : navigationClick() "+e.toString());
}
return true;
}



private class Connection extends Thread
{ 
public Connection()
{ 
super(); 
} 

public void run() { 
Document doc; 
StreamConnection conn = null;

for (int i = 0; i < list.getLength(); i++) {

listElements.addElement(textNode.getNodeValue());
} 

} catch (Exception e) { 
System.out.println(e.toString()); 
} finally { 
if (is != null) { 
try { is.close(); 
} catch (IOException ignored) {} 
} if (conn != null) { 
try { conn.close(); } 
catch (IOException ignored) {} 
} } UiApplication.getUiApplication().invokeLater(new Runnable() {
public void run() { 
_list.setSize(listElements.size()); 
subManager.add(_list);
screen.invalidate();
} 
});
}

}


public void drawListRow(ListField list, Graphics g, int index, int y, int w)

public void insert(String toInsert, int index) {
