從java文件中寫入xml

Question

我的代碼在構建xml結構時存在一些錯誤。有人可以解決這個問題嗎？

public class tulis{ 
     public static void main(String[] args)throws IOException{ 


     BufferedWriter bufferedWriter = new BufferedWriter(new FileWriter("markers3.xml")); 


     sql_connection msconn=new sql_connection(); 
     msconn.connect("gfsat", "root", ""); 
     ResultSet rs=msconn.selectQuery("*", "location"); 
     if(rs!=null) 
     { 
       try 
       { 
        while (rs.next()) 
        { 


     bufferedWriter.write("<marker lat = \""+rs.getString(1)+ "\" lng = \"" +rs.getString(2)+ "\" \nhtml = 'Fish name:"+rs.getString(3)+"&lt;br&gt;Stock:"+rs.getString(4)+"tan metrik&lt;br&gt;Fish length"+rs.getString(5)+"cm&lt;br&gt;Status:" 
            +rs.getString(6)+ "&lt;br&gt;"+ "\n label = \""+rs.getString(7)+"\"\n/>"); 


     bufferedWriter.newLine(); 
       } 
       } catch (SQLException ex){ 
        ex.printStackTrace(); 

     } 
     msconn.disConnect(); 

     bufferedWriter.flush(); 
     bufferedWriter.close(); 
     } 
    } 
    } 

，這裏是從上面的代碼中的XML結構產生..

Answer 1

最大的錯誤：你想直接寫XML字符串，而不是使用XML API。

永遠不要這樣做。

XML API將處理轉義，確保它是一個有效的文件，關閉所有的標記等。Java中有許多XML API - 你可能想看看JDOM是一個相當簡單的API。
