處理XML數據以解析Java中的特殊字符

Question

我剛剛學習如何使用ListView並在此之後使用Java解析XML數據tutorial。但是，由於XML數據包含一些特殊字符，所以出現錯誤。有人可以在這個問題上給我建議嗎？

這是我的XML數據外觀。

<menu> 

<item>  
    <id>1</id> 
    <question>What's my phone number?</question> 
    <answer>my phone number is "000-000-0000".</answer>   
</item> 

<item>  
    <id>2</id> 
    <question>What's my fax number?</question> 
    <answer>my fax number is "000-000-0000"</answer>   
</item> 

<item>  
    <id>3</id> 
    <question>What's my mailing address?</question> 
    <answer>my address here</answer>   
</item> 

<item>  
    <id>4</id> 
    <question>What's my web address?</question> 
    <answer>https://mywebsite.com/Login/Login.aspx?cID=53044&lng=en-US</answer>   
</item> 

</menu> 

這裏是Java類。

public class FaqsQuestionsActivity extends ListActivity { 


    static final String URL = "http://myweb.com/faq_list.xml"; 
    // XML node keys 
    static final String KEY_ITEM = "item"; // parent node 
    static final String KEY_ID = "id"; 
    static final String KEY_QUESTION = "question"; 
    static final String KEY_ANSWER = "answer"; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.faqs_questions); 

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

     XMLParser parser = new XMLParser(); 
     String xml = parser.getXmlFromUrl(URL); // getting XML 
     Document doc = parser.getDomElement(xml); // getting DOM element 

     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); 

      map.put(KEY_ID, parser.getValue(e, KEY_ID)); 
      map.put(KEY_QUESTION, parser.getValue(e, KEY_QUESTION)); 
      map.put(KEY_ANSWER, parser.getValue(e, KEY_ANSWER)); 

      menuItems.add(map); 
     } 

     ListAdapter adapter = new SimpleAdapter(this, menuItems, R.layout.faqs_question_list, 
     new String[] { KEY_QUESTION, KEY_ANSWER }, new int[] {R.id.question, R.id.answer}); 


     setListAdapter(adapter); 

     ListView lv = getListView(); 

     lv.setOnItemClickListener(new OnItemClickListener() { 

      public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 


       String question = ((TextView) view.findViewById(R.id.question)).getText().toString(); 
       String answer = ((TextView) view.findViewById(R.id.answer)).getText().toString(); 


       Intent in = new Intent(getApplicationContext(), FaqsAnswersActivity.class); 

       in.putExtra(KEY_QUESTION, question); 
       in.putExtra(KEY_ANSWER, answer); 
       startActivity(in); 

      } 
     }); 
    } 
}

你可以嘗試嘗試分析它之前，你的XML編碼：

String encodedXML = URLEncoder.encode(xml); 

，然後解析。
