给你写个例子，参考下吧。很容易，楼主可以自己修改处理更复杂的
- Java code
import java.io.File;import java.io.FileOutputStream;import java.util.List;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 XMLCom{ public static void main(String[] args) { SAXReader reader = new SAXReader(); File file = new File("d:\\test.xml"); File file1 = new File("d:\\test1.xml"); try { Document document = reader.read(file); Document document1 = reader.read(file1); List<Element> infos = document.selectNodes("root/info"); List<Element> infos1 = document1.selectNodes("root/info"); for(int i = 0;i < infos.size();i++){ Element info = infos.get(i); Element info1 = infos1.get(i); List<Element> ls = info1.elements(); Element add = (Element)ls.get(0).clone(); info.add(add); } OutputFormat format = new OutputFormat(); format = OutputFormat.createPrettyPrint(); XMLWriter output = null; output = new XMLWriter(new FileOutputStream(new File("d://comtest.xml")), format); output.write(document); output.close(); }catch(Exception e){ e.printStackTrace(); } }}
