JAVA jdom解析xml简单用法

import java.io.File;
import java.io.IOException;
import java.util.List;

import org.jdom.Document;
import org.jdom.Element;
import org.jdom.JDOMException;
import org.jdom.input.SAXBuilder;

public class JdomTest {

public static void main(String[] args) throws JDOMException, IOException {
// TODO Auto-generated method stub
//获取解析xml文件路径
String path = System.getProperty("user.dir")+"/bin/stdent.xml";//System.getProperty("user.dir")得到的是项目真实路径
File file = new File(path);
//通过文件获取xml全部内容
SAXBuilder saxBuilder = new SAXBuilder();
Document document = saxBuilder.build(file);
//获取xml文件根节点
Element root = document.getRootElement();
//获取根节点的属性
String name = root.getAttributeValue("name");
//获得子节点
Element child = root.getChild("colgroup");
//获得全部子节点
List<Element> cols = child.getChildren();

}

}
