IDEA中解析xml文件，进行删除操作时遇到的问题

之前未接触过java代码（编程方面知识匮乏），求各位帮忙指点一下这里，以下是代码

package com.shk.xml;

import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.Element;
import org.dom4j.io.OutputFormat;
import org.dom4j.io.SAXReader;
import org.dom4j.io.XMLWriter;

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

public class XMLDeleteTest1 {

        public static void main(String[] args) {

            int deleteId = 1004;
            File file = new File("data/student.xml");
            SAXReader saxReader = new SAXReader();
            XMLWriter xmlWriter = null;
            try {
                Document document = saxReader.read(file);
                List<Element> ordEleList = document.selectNodes("/orders/order");
                for ( Element ordEle = ordEleList) {
                    if (ordEle.elementText("id").equals(String.valueOf(deleteId))) {
                        ordEle.getParent().remove(ordEle);
                        break;
                    }
                }
                OutputFormat outputFormat = OutputFormat.createPrettyPrint();
                xmlWriter = new XMLWriter(new FileWriter(file), outputFormat);
                xmlWriter.write(document);
            } catch (DocumentException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            } finally {
                if (xmlWriter != null){
                    try {
                        xmlWriter.close();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }
            }

        }
}

for里面的 = 换成 : 再试试

import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.Element;
import org.dom4j.io.OutputFormat;
import org.dom4j.io.SAXReader;
import org.dom4j.io.XMLWriter;

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

public class XMLDeleteTest1 {

    public static void main(String[] args) {

        int deleteId = 1004;
        File file = new File("data/student.xml");
        SAXReader saxReader = new SAXReader();
        XMLWriter xmlWriter = null;
        try {
            Document document = saxReader.read(file);
            List<Element> ordEleList = document.selectNodes("/orders/order");
            for (Element ordEle : ordEleList) {
                if (ordEle.elementText("id").equals(String.valueOf(deleteId))) {
                    ordEle.getParent().remove(ordEle);
                    break;
                }
            }
            OutputFormat outputFormat = OutputFormat.createPrettyPrint();
            xmlWriter = new XMLWriter(new FileWriter(file), outputFormat);
            xmlWriter.write(document);
        } catch (DocumentException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (xmlWriter != null) {
                try {
                    xmlWriter.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }

    }
}

  在orders表当中添加一些数据
  

  

  package cn.itbluebox.domain;
  
  import java.util.Date;
  
  public class Orders {
  
      private int id;
      private Date ordertime;
      private double total;
  
      //代表当前订单从属于哪一个客户
      private User user;
  
      public Orders() {
      }
  
      public Orders(int id, Date ordertime, double total, User user) {
          this.id = id;
          this.ordertime = ordertime;
          this.total = total;
          this.user = user;
      }
  
      public int getId() {
          return id;
      }
  
      public void setId(int id) {
          this.id = id;
      }
  
      public Date getOrdertime() {
          return ordertime;
      }
  
      public void setOrdertime(Date ordertime) {
          this.ordertime = ordertime;
      }
  
      public double getTotal() {
          return total;
      }
  
      public void setTotal(double total) {
          this.total = total;
      }
  
      public User getUser() {
          return user;
      }
  
      public void setUser(User user) {
          this.user = user;
      }
  
      @Override
      public String toString() {
          return "Order{" +
                  "id=" + id +
                  ", ordertime=" + ordertime +
                  ", total=" + total +
                  ", user=" + user +
                  '}';
      }
  }
