用java DOM4j实现xml节点的复制

用java DOM4j实现xml节点的复制

那你就获得root节点，然后再追加append你的clone的那个args节点就可以了呀追问Element rootCheck = domCheck.getRootElement();
为什么这个root 只有add方法 没有append方法追答package com.htsa.tools.db;

import java.io.File;
import java.io.FileWriter;
import org.dom4j.Document;
import org.dom4j.Element;
import org.dom4j.io.OutputFormat;
import org.dom4j.io.SAXReader;
import org.dom4j.io.XMLWriter;

public class ModifyXML

OutputFormat outFmt = null;
try
{
file = new File ("test_3.xml");
saxReader = new SAXReader ();
document = saxReader.read (file);
Element root = document.getRootElement ();
Element fc = (Element) root.elements ().get (0);
Element cloned = (Element) fc.clone ();
cloned.addAttribute ("hello", "world");
root.add (cloned);
outFmt = new OutputFormat (" ", true);
outFmt.setEncoding ("UTF-8");
fw = new FileWriter (file);
xmlWriter = new XMLWriter (fw, outFmt);
xmlWriter.write (document);
fw.flush ();
xmlWriter.flush ();
xmlWriter.close ();
fw.close ();
}
catch (Exception e)
{
e.printStackTrace ();
}
}
}
