XmlPullParser解析xml文件

xml:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:web="http://webservice.datasource.gosun.com/">
    <soapenv:Header></soapenv:Header>
    <soapenv:Body>
        <AddRecordRes>
            <code>14</code>
            <message>成功</message>
        </AddRecordRes>
    </soapenv:Body>
</soapenv:Envelope>

public String createXml() {    
    StringBuilder sb = new StringBuilder("<soapenv:Envelope " + 
        "xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" " +            
        "xmlns:web=\"http://webservice.datasource.gosun.com/\">");     
    sb.append("<soapenv:Header></soapenv:Header>" + "<soapenv:Body>" +            
        "<AddRecordRes>" + "<code>14</code>" + "<message>成功</message>" +            
        "</AddRecordRes>" + "</soapenv:Body>" + "</soapenv:Envelope>"    );    
    return sb.toString();
}

解析函数 getCommXml(String xml)

public static String getCommXml(String xml) {    
    String commXml = null;    
    if (xml == null) {        
        return null;    
    }    
    Log.i("dido", xml);    
    InputStream inputStream = new ByteArrayInputStream(xml.getBytes());   
    try {        
        XmlPullParserFactory factory = XmlPullParserFactory.newInstance();        
        XmlPullParser parser = factory.newPullParser();        
        parser.setInput(inputStream,"UTF-8"); // 设置数据源编码        
        int eventType = parser.getEventType(); //获取事件类型       
        while (eventType != XmlPullParser.END_DOCUMENT) {     
            switch (eventType) {                
                case XmlPullParser.START_TAG: // 开始读取某个标签                    
                    Log.i("Start tag ", parser.getName());                    
                    break;                
                case XmlPullParser.TEXT:                    
                    commXml = parser.getText();                    
                    Log.i("Text ", parser.getText());                    
                    break;                
                case XmlPullParser.END_TAG:                    
                    Log.i("End tag ", parser.getName());                    
                    break;            
            }            
            eventType = parser.next();        
        }        
        inputStream.close();    
    } catch (Exception e) {        
        e.printStackTrace();    
    }    
    return commXml;
}

输出：
