Dom4j递归输出所有的接点和值

Dom4j递归输出所有的接点和值

 

这个程序是一个要显示程序调用关系xml配置，帮同事写的，拿出来分享下：

 

import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;

import java.util.List;

public class Test {

         public static void main(String[] args) throws DocumentException {
                Document doc = DocumentHelper.parseText(xml);
                Element root = doc.getRootElement();
                doit(root);
        }

         private static void doit(Element e) {
                List<Element> els = e.elements();
                 for (Element el : els) {
                         //判断是否复合节点
                         if(!el.hasMixedContent()){
                                System.out.println(el.getPath()+ ":"+el.getText());
                        } else{
                                System.out.println(el.getPath());
                                doit(el);
                        }
                }
        }

         private static String xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" +
                         "<app>\n" +
                         "\t<srv>\n" +
                         "\t\t<cn>aaaaaaaaaaaaaaaaaaaaaa</cn>\n" +
                         "\t\t<mn>modifyService</mn>\n" +

}

 

输出结果：
