從對話框中刪除標籤

Question

我無法從我的代碼輸出中刪除SSP和/ SSP標籤，該代碼出現在我輸出的對話框中。

我已經嘗試了幾種不同的方法來刪除標籤，但似乎不能請你建議如何修改下面的代碼，以便我可以刪除這些標籤。我對Java很新。

import javax.swing.JOptionPane; 
import java.io.IOException; 
import java.util.logging.*; 
import org.jsoup.*; 
import org.jsoup.nodes.*; 
import org.jsoup.select.*; 

public class SimpleDialogBox { 

    /** 
    * @param args the command line arguments 
    */ 
    public static void main(String[] args) { 
     // TODO code application logic here 
     try { 
     String url = "http://bmreports.com/bsp/additional/soapfunctions.php?element=SYSPRICE&dT=NRT"; 
     Document doc = Jsoup.connect(url).get(); 
     Elements SSPparagraphs; 
    SSPparagraphs = doc.select("SSP"); 
    //paragraphs = doc.select("SBP"); 
    System.out.println(SSPparagraphs.text()); 

     (Element SSPparagraphs : paragraphs) 
     JOptionPane.showMessageDialog(

     null, SSPparagraphs, "Cashout Prices", JOptionPane.PLAIN_MESSAGE); 
     System.exit(0); 


    } 

     catch (IOException ex) { 
    Logger.getLogger(SimpleDialogBox.class.getName()) 
     .log(Level.SEVERE, null, ex); 
    } 
} 


} 

Answer 1

在對話框

JOptionPane.showMessageDialog(null, SSPparagraphs, "Cashout Prices", JOptionPane.PLAIN_MESSAGE); 

加 '的.text（）' 到SSparagraphs

JOptionPane.showMessageDialog(null, SSPparagraphs.text(), "Cashout Prices", JOptionPane.PLAIN_MESSAGE); 

然後，爲了獲得不同的線路輸出，我改變了代碼。我將輸出分配給一個字符串，然後將其分配到空格上。然後我在對話框和控制檯輸出中顯示格式化的字符串。

import javax.swing.JOptionPane; 
import java.io.IOException; 
import java.util.logging.*; 
import org.jsoup.*; 
import org.jsoup.nodes.*; 
import org.jsoup.select.*; 

public class SimpleDialogBox 
{ 
    public static void main(String[] args) 
    { 
     // TODO code application logic here 
     try 
     { 
      String url = "http://bmreports.com/bsp/additional/soapfunctions.php?element=SYSPRICE&dT=NRT"; 
      Document doc = Jsoup.connect(url).get(); 
      Elements SSPparagraphs; 
      SSPparagraphs = doc.select("SSP"); 
      //paragraphs = doc.select("SBP"); 

      String[] numbers = SSPparagraphs.text().toString().split(" "); 
      String formattedText = new String(""); 
      for (int x = 0; x < numbers.length; x++) 
      { 
       formattedText += numbers[x] + "\n"; 
      } 

      System.out.println(formattedText); 

      //(Element paragraphs : SSPparagraphs) 
      JOptionPane.showMessageDialog(
       null, formattedText, "Cashout Prices", JOptionPane.PLAIN_MESSAGE); 
      System.exit(0); 
     } 
     catch (IOException ex) 
     { 
      Logger.getLogger(SimpleDialogBox.class.getName()) 
      .log(Level.SEVERE, null, ex); 
     } 
     }
