閱讀從控制檯打印在XML文件輸出在java中

Question

可能重複：
How could I read Java Console Output into a String buffer

我知道如何從用戶讀取輸入，並把它放在XML file.Here是示例： 從http://www.mkyong.com/java/how-to-create-xml-file-in-java-dom/

import java.io.File; 
import javax.xml.parsers.DocumentBuilder; 
import javax.xml.parsers.DocumentBuilderFactory; 
import javax.xml.parsers.ParserConfigurationException; 
import javax.xml.transform.Transformer; 
import javax.xml.transform.TransformerException; 
import javax.xml.transform.TransformerFactory; 
import javax.xml.transform.dom.DOMSource; 
import javax.xml.transform.stream.StreamResult; 

import org.w3c.dom.Attr; 
import org.w3c.dom.Document; 
import org.w3c.dom.Element; 

public class WriteXMLFile { 

    public static void main(String argv[]) { 

     try { 

     DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance(); 
     DocumentBuilder docBuilder = docFactory.newDocumentBuilder(); 

     // root elements 
     Document doc = docBuilder.newDocument(); 
     Element rootElement = doc.createElement("company"); 
     doc.appendChild(rootElement); 

     // staff elements 
     Element staff = doc.createElement("Staff"); 
     rootElement.appendChild(staff); 

     // set attribute to staff element 
     Attr attr = doc.createAttribute("id"); 
     attr.setValue("1"); 
     staff.setAttributeNode(attr); 

     // shorten way 
     // staff.setAttribute("id", "1"); 

     // firstname elements 
     Element firstname = doc.createElement("firstname"); 
     firstname.appendChild(doc.createTextNode("yong")); 
     staff.appendChild(firstname); 

     // lastname elements 
     Element lastname = doc.createElement("lastname"); 
     lastname.appendChild(doc.createTextNode("mook kim")); 
     staff.appendChild(lastname); 

     // nickname elements 
     Element nickname = doc.createElement("nickname"); 
     nickname.appendChild(doc.createTextNode("mkyong")); 
     staff.appendChild(nickname); 

     // salary elements 
     Element salary = doc.createElement("salary"); 
     salary.appendChild(doc.createTextNode("100000")); 
     staff.appendChild(salary); 

     // write the content into xml file 
     TransformerFactory transformerFactory = TransformerFactory.newInstance(); 
     Transformer transformer = transformerFactory.newTransformer(); 
     DOMSource source = new DOMSource(doc); 
     StreamResult result = new StreamResult(new File("C:\\file.xml")); 

     // Output to console for testing 
     // StreamResult result = new StreamResult(System.out); 

     transformer.transform(source, result); 

     System.out.println("File saved!"); 

     } catch (ParserConfigurationException pce) { 
     pce.printStackTrace(); 
     } catch (TransformerException tfe) { 
     tfe.printStackTrace(); 
     } 
    } 
} 

但我的問題是浩w從java中讀取控制檯的輸出並將其輸出到指定的XML文件中。

我不確定您的意思是「從控制檯讀取輸出」，但您可以使用http://docs.oracle.com/javase/6/docs/api/java/lang/System.html#setOut%28java.io.PrintStream%29攔截對System.out的調用。
如果您詳細說明您正在嘗試做什麼，我可以更具體。
