java如何获得正确的Unicode字符串（无&#enties；）从绝地武士那里？

8 月，1 周 Questions & Answers 526

我需要从jtextpane中获取文本，其格式为我在设置文本中输入的内容

  private void test() {
      myFrame = new JFrame("JEditorPane Unicode Test");
      myFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      myFrame.setSize(300,200);

      myPane = new JEditorPane();
      myPane.setContentType("text/html;charset=utf-8");
      myPane.setText(
         "Hello computer! - \u7535\u8111\u4F60\u597D\uFF01\n"
         + "Welcome to Herong's Website!\n"
         + "\u6B22\u8FCE\u4F60\u8BBF\u95EE\u548C\u8363\u7F51\u7AD9"
         + "\uFF01\nwww.herongyang.com <br>பாரதீய ஜனதா இளைஞர் அணி <b>தலைவர் அனுராக்சிங் தாகூர் எம்.பி.<b> நேற்று தேர்தல் <i>ஆணையர் வி.சம்பத்தை<i>");
      myFrame.setContentPane(myPane);
      String test = myPane.getText();
       try {
        JOptionPane.showMessageDialog(null, "myPane.gettext --> "+myPane.getText());
           System.out.println("myPane.getText() -->"+myPane.getText());
       } catch (Exception ex) {
           Logger.getLogger(JEditorPaneUnicode.class.getName()).log(Level.SEVERE, null, ex);
       }


    @Override
    public void actionPerformed(ActionEvent e) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }
}

但是我的get文本输出如下

myPane.getText()→

<html>
   <head>

   </head>
   <body>

  </body>
  </html>

我的预期产出是

  <html>
  <head>

  </head>
  <body>

doc = (HTMLDocument) myPane.getDocument(); StringBuilder sb = new StringBuilder(); javax.swing.text.Element[] styles = doc.getRootElements(); for (int i = 0; i < styles.length; i++) { int size = styles[i].getElementCount(); if (!styles[i].getName().contains("bidi root")) { // System.out.println("<"+styles[i].getName()+">"); // sb.append("<"+styles[i].getName()+">"); } for (int j = 0; j < size; j++) { String element = styles[i].getElement(j).getName(); if (element.equals("body")) { int subsize = styles[i].getElement(j).getElementCount(); for (int k = 0; k < subsize; k++) { element = styles[i].getElement(j).getElement(k).getName(); if (element.equals("p-implied")) { int subsubsize = styles[i].getElement(j).getElement(k).getElementCount(); String cond = "fail", boldc = "</b>", boldi = "</i>"; for (int l = 0; l < subsubsize; l++) { javax.swing.text.Element elem = styles[i].getElement(j).getElement(k).getElement(l); element = elem.getName(); if (!element.contains("content")) { // System.out.println("<"+element+">"); sb.append("<" + element + ">"); } if (element.equals("content")) { AttributeSet attributes = elem.getAttributes(); Enumeration attrs = attributes.getAttributeNames(); while (attrs.hasMoreElements()) { String rft = attrs.nextElement().toString(); if (rft.equals("b")) { // System.out.println("<"+rft+">"); sb.append("<" + rft + ">"); cond = "passb"; } else if (rft.equals("i")) { sb.append("<" + rft + ">"); cond = "passi"; } } } try { // System.out.println( elem.getDocument().getText(elem.getStartOffset(), (elem.getEndOffset() - elem.getStartOffset()))); sb.append(elem.getDocument().getText(elem.getStartOffset(), (elem.getEndOffset() - elem.getStartOffset()))); } catch (BadLocationException ex) { Logger.getLogger(GridEditor.class.getName()).log(Level.SEVERE, null, ex); } if (cond.equals("passi")) { // System.out.println( boldi); sb.append(boldi); } if (cond.equals("passb")) { // System.out.println( boldc); sb.append(boldc); } cond = "fail"; } } } } } } String text = sb.toString(); System.out.println("final string > "+text);

有 Java 编程相关的问题?
