【问题描述】：

我想解析来自 Google Calender xml 提要的事件

https://www.google.com/calendar/feeds/sjm6mdaoghv5kipc2p80jrgsc0%40group.calendar.google.com/public/basic

我想从以下标签解析数据：

busy and  Wed Oct 9, 2013 4pm to 5pm

有人可以帮忙吗？

【问题讨论】：

你在 XML Parsing 上尝试过什么？

【参考方案1】：

我有东西要给你

XML 解析器类

package com.kodspider.xml;

public class XMLParser 

    // constructor
    public XMLParser() 

    

    /**
     * Getting XML from URL making HTTP request
     * @param url string
     * */
    public String getXmlFromUrl(String url) 
        String xml = null;

        try 
            // defaultHttpClient
            DefaultHttpClient httpClient = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost(url);

            HttpResponse httpResponse = httpClient.execute(httpPost);
            HttpEntity httpEntity = httpResponse.getEntity();
            xml = EntityUtils.toString(httpEntity);

         catch (UnsupportedEncodingException e) 
            e.printStackTrace();
         catch (ClientProtocolException e) 
            e.printStackTrace();
         catch (IOException e) 
            e.printStackTrace();
        
        // return XML
        return xml;
    

    /**
     * Getting XML DOM element
     * @param XML string

    public Document getDomElement(String xml)
        Document doc = null;
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        try 

            DocumentBuilder db = dbf.newDocumentBuilder();

            InputSource is = new InputSource();
                is.setCharacterStream(new StringReader(xml));
                doc = db.parse(is); 

             catch (ParserConfigurationException e) 
                Log.e("Error: ", e.getMessage());
                return null;
             catch (SAXException e) 
                Log.e("Error: ", e.getMessage());
                return null;
             catch (IOException e) 
                Log.e("Error: ", e.getMessage());
                return null;
            

            return doc;
    

    /** Getting node value
      * @param elem element
      */
     public final String getElementValue( Node elem ) 
         Node child;
         if( elem != null)
             if (elem.hasChildNodes())
                 for( child = elem.getFirstChild(); child != null; child = child.getNextSibling() )
                     if( child.getNodeType() == Node.TEXT_NODE  )
                         return child.getNodeValue();
                     
                 
             
         
         return "";
     

     /**
      * Getting node value
      * @param Element node
      * @param key string
      * */
     public String getValue(Element item, String str)      
            NodeList n = item.getElementsByTagName(str);        
            return this.getElementValue(n.item(0));
        

将此类与附加库一起使用 - htmlcleaner-2.2.1.jar

下载here

您可以使用以下嵌入在...中的代码来解析您的活动类中的数据。

代码

// XML parsing data types and nodes

        // All static variables
        static final String URL = "your XML data path";
        // XML node keys
        static final String KEY_ITEM = "item"; // parent node(to check every nodes)
        static final String TAG1 = "busy";
        static final String TAG2 = "and"; // etc 

试试这个...

使用 AsyncTask 的带有 CustomAdapter 的 RSS 解析器
