经过一些操作后，我得到了来自服务器的 bewlow xml 响应。现在我需要从这些标签中获取数据。请指导我如何获得它。

   <?xml version="1.0" encoding="utf-8"?>
    <Response xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.org/">
    <Result xmlns="GlobalPayments">0</Result>
    <RespMSG xmlns="GlobalPayments">Approved</RespMSG>
    <Message xmlns="GlobalPayments">AP</Message>
    <AuthCode xmlns="GlobalPayments">01245F</AuthCode>
    <PNRef xmlns="GlobalPayments">170015964</PNRef>
    <HostCode xmlns="GlobalPayments">002</HostCode>
    <GetCVResultTXT xmlns="GlobalPayments">Service Not Requested</GetCVResultTXT>
    <GetCommercialCard xmlns="GlobalPayments">True</GetCommercialCard>
    <ExtData xmlns="GlobalPayments">CardType=Visa,BatchNum=0202&lt;BatchNum&gt;0202&lt;/BatchNum&gt;&lt;ReceiptData&gt;&lt;MID&gt;87228799&lt;/MID&gt;&lt;Trans_Id&gt;283220167525&lt;/Trans_Id&gt;&lt;Val_Code&gt;52ND&lt;/Val_Code&gt;&lt;/ReceiptData&gt;</ExtData>

</Response>

我正在使用下面的代码，问题是 XmlPullParser.START_TAG:提供了 xml 中可用的整个标签，而不需要一个标签。

 package com.parsing_new;

    import java.io.InputStream;
    import java.util.ArrayList;

             parser.setInput(in_s, null);
             parseXML(parser);

  }
  TextView display = (TextView)findViewById(R.id.textView1);
  display.setText(content);
 }

}

请指导我如何做到这一点。

尝试这个

private void parseXML(XmlPullParser parser) throws XmlPullParserException, IOException {
        Log.e("ParsingActivity",">>>>>>>>>>>>>>>>>.. parseXML.................." );
        ArrayList<Response> responses = new ArrayList<Response>();
        int eventType = parser.getEventType();
        Response currentProduct = null;

        while (eventType != XmlPullParser.END_DOCUMENT) {
            switch (eventType){
            case XmlPullParser.START_DOCUMENT:
                break;
            case XmlPullParser.START_TAG:
                String name = parser.getName();
                Log.e("ParsingActivity", " >>>>>.... Tag name   = " + name);
                if (name.equals("Response")) {
                    currentProduct = new Response();
                } else if (name.equals("Result")) {
                    currentProduct.Reslt = parser.nextText();
                } else if (name.equals("RespMSG")) {
                    currentProduct.Respmsg = parser.nextText();
                } else if (name.equals("Message")) {
                    currentProduct.Msg = parser.nextText();
                } else if (name.equals("AuthCode")) {
                    currentProduct.Auth = parser.nextText();
                } else if (name.equals("PNRef ")) {
                    currentProduct.Pnref = parser.nextText();
                } else if (name.equals("HostCode ")) {
                    currentProduct.Host = parser.nextText();
                } else if (name.equals("GetCVResultTXT ")) {
                    currentProduct.Getcv = parser.nextText();
                } else if (name.equals("GetCommercialCard")) {
                    currentProduct.Getcom = parser.nextText();
                } else if (name.equals("ExtData")) {
                    currentProduct.Ext = parser.nextText();
                }

                break;
            case XmlPullParser.END_TAG:
                name = parser.getName();
                if (name.equals("Response")) {
                    responses.add(currentProduct);
                }
                break;
            }
            eventType = parser.next();
        }

        printProducts(responses);
    }
