XML轉換期限前P0DT1H0M0S到Java

Question

嗨，我試圖讀取XML持續到一個新的持續時間，但是I'T說 「無法實例類型持續時間」

我很新的Java和Android開發。所以請保持任何nonconstructive評論自己..

代碼

import javax.xml.datatype.Duration; 

Duration duration = new Duration(); 

Answer 1

找到它自己。

 try { 
      DatatypeFactory dtFactory = DatatypeFactory.newInstance(); 
     } catch (DatatypeConfigurationException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 

Duration duration = dtFactory.newDuration("p0dt1h0m0s"); 

編輯..

以上是不可能的，因爲一個錯誤的DatatypeFactory SOOO我建這個類來解決它自己..

public class XmlDuration { 
    private String _xmlDuration; 
    private int _years; 
    private int _months; 
    private int _days; 
    private int _hours; 
    private int _minutes; 
    private int _seconds; 

    private boolean _isNegative; 

    public XmlDuration(String xmlDuration) { 
     try { 

      _xmlDuration = xmlDuration; 

      _isNegative = ((String)_xmlDuration.subSequence(0,1)).matches("[-]"); 

      String period; 
      String time; 

      int tIndex =_xmlDuration.indexOf("T"); 

      period = xmlDuration.substring(0, tIndex); 
      time = _xmlDuration.substring(tIndex); 

      String numericSection = ""; 

      for (int i = 0; i < period.length(); i++) { 
       char[] c = new char[] {period.charAt(i)}; 
       String s = new String(c);     

       if(s.matches("\\d")) 
       { 
        numericSection += s; 
       } 
       else if (s.matches("[Yy]")) 
       { 
        _years = Integer.parseInt(numericSection); 
        numericSection = ""; 
       } 
       else if (s.matches("[Mm]")) 
       { 
        _months = Integer.parseInt(numericSection); 
        numericSection = ""; 
       } 
       else if (s.matches("[Dd]")) 
       { 
        _days = Integer.parseInt(numericSection); 
        numericSection = ""; 
       } 

      } 

      for (int i = 0; i < time.length(); i++) { 
       char[] c = new char[] {time.charAt(i)}; 
       String s = new String(c); 

       if(s.matches("\\d")) 
       { 
        numericSection += s; 
       } 
       else if (s.matches("[Hh]")) 
       { 
        _hours = Integer.parseInt(numericSection); 
        numericSection = ""; 
       } 
       else if (s.matches("[Mm]")) 
       { 
        _minutes = Integer.parseInt(numericSection); 
        numericSection = ""; 
       } 
       else if (s.matches("[Ss]")) 
       { 
        _seconds = Integer.parseInt(numericSection); 
        numericSection = ""; 
       }  

      } 

     } catch (Exception e) { 
      // TODO: handle exception 
     } 



    } 

    public String getXmlString() 
    { 
     return _xmlDuration; 
    } 

    public int getYears() 
    { 
     return _years; 
    } 

    public int getMonth() 
    { 
     return _months; 
    } 

    public int getDays() 
    { 
     return _days; 
    } 

    public int getHours() 
    { 
     return _hours; 
    } 

    public int getMinutes() 
    { 
     return _minutes; 
    } 

    public int getSeconds() 
    { 
     return _seconds; 
    } 

    public boolean getIsNegative() 
    { 
     return _isNegative; 
    }
