<title>The Return of Toastmasters</title> 
<link>http://www.younginnovations.com.np/blogs/anjan/2012/06/return-toastmasters</link> 
<description>&lt;p&gt;As the title implies, it was the &lt;strong&gt;return of the Toastmasters&lt;/strong&gt; at YoungInnovations on Thursday, May 24, 2012. I said &amp;quot;return&amp;quot; because Toastmasters saw a long gap of more than 3 months. Why the delay? Well, we shifted to a new office building and it took us some time to adjust properly into the new place. However, we&#039;re all glad that we continued with the event even after a long gap. And rightfully so, the MC for the day, Bimal Maharjan, announced the theme for the meeting: Return.&lt;/p&gt;

和我的应用程序代码值低于 News.java

import java.util.ArrayList; 
import java.util.HashMap; 

import org.w3c.dom.Document; 
import org.w3c.dom.Element; 
import org.w3c.dom.NodeList; 

import android.app.ListActivity; 
import android.content.Intent;

public class News extends ListActivity { 

    static final String URL = "http://www.younginnovations.com.np/blog/feed"; 
    static final String KEY_ITEM = "item"; 
    static final String KEY_TITLE = "title"; 
    static final String KEY_DESC = "description"; 
    static final String KEY_DATE = "pubDate"; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 

     super.onCreate(savedInstanceState); 
     setContentView(R.layout.news); 

     ArrayList<HashMap<String, String>> menuItems = new ArrayList<HashMap<String, String>>(); 

     XMLParser parser = new XMLParser(); 
     String xml = parser.getXmlFromUrl(URL); 
     Document doc = parser.getDomElement(xml); 

     NodeList nl = doc.getElementsByTagName(KEY_ITEM); 

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

      HashMap<String, String> map = new HashMap<String, String>(); 
      Element e = (Element) nl.item(i); 

      Log.e("Element", e.toString()); 
      System.out.println(e); 

      map.put(KEY_TITLE, parser.getValue(e, KEY_TITLE)); 
      map.put(KEY_DATE, parser.getValue(e, KEY_DATE)); 
      map.put(KEY_DESC, parser.getValue(e, KEY_DESC)); 


      menuItems.add(map); 
     } 


     ListAdapter adapter = new SimpleAdapter(this, menuItems, 
       R.layout.news_list_item, 
       new String[] { KEY_TITLE, KEY_DESC, KEY_DATE }, new int[] { 
         R.id.name, R.id.desciption, R.id.cost }); 

     setListAdapter(adapter); 
    } 
    }

和XMLParse.java

import android.util.Log; 

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)); 
     } 
}

但同时获得<description>标签的价值..有HTML标签。因此，“<”作为值返回。在其他情况下，它完全正常。我怎样才能得到所有的值，或在最好的情况下，我怎样才能不包括HTML标记值..

提前等待帮助，感谢

更改为JSON代表已下载的XML内容并将其用于数据操作。 - 检查链接 http://stackoverflow.com/questions/7724263/how-to-convert-xml-to-json-in-java – 2012-08-13 11:30:27

需要在XML本身工作..不能在转换过程.. – user98239820 2012-08-13 11:36:33

如果您在标记中收到HTML内容作为响应，则应在服务器端完成修复，将其全部转换为格式正确的数据，或者在任何WebView中加载整个描述内容。 – 2012-08-13 11:43:58

谢谢大家的支持。但我解决它不同的方式...

我确实在XMLParser.java文件中的一些变化...

public final String getElementValue(Node elem) { 
    Node child; 
    String returnValue = "" ; 
    if(elem != null){ 
     if (elem.hasChildNodes()){ 
      for(child = elem.getFirstChild(); child != null; child = child.getNextSibling()){ 
       if(child.getNodeType() == Node.TEXT_NODE){ 
        // String returnValue = child.getNodeValue(); 
        returnValue += child.getTextContent(); 
       } 

      } 
     // Log.e("ReturnValue", Html.fromHtml(returnValue).toString()); 
      return Html.fromHtml(returnValue).toString(); 
     } 
    } 
    return ""; 
}

但我仍然有一个问题。如果在xml中有图片，则返回为“obj”，我不想看到它。
