用dom 解析 XML 文件

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
 
public class test {
       
  public static void main(String[] args) throws Exception {
   
    //1.創建工廠
    
   DocumentBuilderFactory factory =  DocumentBuilderFactory.newInstance();
   //2.得到dom解析器
   DocumentBuilder builder =  factory.newDocumentBuilder();
   
   //3.解析文檔，得到對應的document
   Document document = builder.parse("src/xxx.xml ");
 }
}
