篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了java 怎样解析 excel生成的xml文件相关的知识，希望对你有一定的参考价值。
java解析excel生成的xml文件的方法是使用dom4j实现的。dom4j是一个简单的开源库，用于处理XML、 XPath和XSLT，它基于Java平台，使用Java的集合框架，全面集成了DOM，SAX和JAXP。
1、excel生成的xml样例文件：
<?xml version="1.0"?>
<?mso-application progid="Excel.Sheet"?>
<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet"

<WindowTopY>168</WindowTopY>
<ActiveSheet>2</ActiveSheet>
<ProtectStructure>False</ProtectStructure>
<ProtectWindows>False</ProtectWindows>
</ExcelWorkbook>

2、java解析代码：
import java.io.File;
import java.util.Iterator;
import org.dom4j.Attribute;
import org.dom4j.Document;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;
public class Demo
public static void main(String[] args) throws Exception
SAXReader reader = new SAXReader();
Document document = reader.read(new File("person.xml"));
Element root = document.getRootElement();
Iterator it = root.elementIterator();
while (it.hasNext())
Element element = (Element) it.next();
//未知属性名称情况下
/*Iterator attrIt = element.attributeIterator();
while (attrIt.hasNext())
Attribute a = (Attribute) attrIt.next();
System.out.println(a.getValue());
*/
//已知属性名称情况下
System.out.println("id: " + element.attributeValue("id"));
//未知元素名情况下
/*Iterator eleIt = element.elementIterator();
while (eleIt.hasNext())
Element e = (Element) eleIt.next();
System.out.println(e.getName() + ": " + e.getText());
System.out.println();*/
//已知元素名情况下
System.out.println("title: " + element.elementText("title"));
System.out.println("author: " + element.elementText("author"));
System.out.println();
参考技术A python可以的，java有困难
新生成的xml文件名称使用excel文件名。 当然这个的前提得会解析excel文件，上一篇文章说了Python如何解析excel文件。这里使用python 自带的xml库：xml.dom来生成xml。
java 生成和解析xml
本文主要使用的是Jdom.jar包（包的下载百度一下）实现了生成xml文件和解析xml文件
下面是生成xml的实现
说明：stuLists集合是一个存放着Student对象的集合
1 import java.io.File; 2 import java.io.FileNotFoundException; 3 import java.io.FileOutputStream; 4 import java.io.IOException; 5 import java.util.ArrayList; 6 7 import org.jdom.Document; 8 import org.jdom.Element; 9 import org.jdom.input.SAXBuilder; 10 import org.jdom.output.Format; 11 import org.jdom.output.XMLOutputter; 12 13 public class AddXml { 14 public static void main(String[] args) { 15 new AddXml().changeXml(); 16 } 17 public void changeXml(){ 18 Jdbc jdbc = new Jdbc(); 19 jdbc.addList(); 20 ArrayList<Student> stuLists = Jdbc.getStuList(); 21 22 Document docu = new Document(); 23 Element root = new Element("root"); 24 docu.addContent(root); 25 for (int i = 0; i < stuLists.size(); i++) { 26 // System.out.println(stuLists.get(i)); 27 Student s = stuLists.get(i); 28 29 Element info = new Element("info"); 30 Element student = new Element("student"); 31 Element id = new Element("id"); 32 Element name = new Element("name"); 33 Element sex = new Element("sex"); 34 Element age = new Element("age"); 35 36 Element book = new Element("book"); 37 Element bid = new Element("bid"); 38 Element bname = new Element("bname"); 39 Element bprice = new Element("bprice"); 40 Element bautor = new Element("bautor"); 41 book.addContent(bid); 42 book.addContent(bname); 43 book.addContent(bprice); 44 book.addContent(bautor); 45 46 student.addContent(id); 47 student.addContent(name); 48 student.addContent(sex); 49 student.addContent(age); 50 info.addContent(student); 51 info.addContent(book); 52 53 root.addContent(info); 54 int a = i+1; 55 String No = "000"+a; 56 student.setAttribute("No", No); 57 id.setText(s.getId()); 58 name.setText(s.getName()); 59 sex.setText(s.getSex()); 60 age.setText(s.getAge()); 61 62 String b="0"+a; 63 bid.setText(b); 64 bname.setText("java核心"); 65 bprice.setText("1334.0"); 66 bautor.setText("star"); 67 68 } 69 //格式化生成的xml文件，如果不进行格式化的话，生成的xml文件将会是很长的一行... 70 Format format = Format.getCompactFormat(); 71 format.setEncoding("utf-8"); 72 format.setIndent(" "); 73 XMLOutputter xo = new XMLOutputter(format); 74 try { 75 xo.output(docu, new FileOutputStream(new File("e:/io/stu.xml"))); 76 } catch (FileNotFoundException e) { 77 // TODO Auto-generated catch block 78 e.printStackTrace(); 79 } catch (IOException e) { 80 // TODO Auto-generated catch block 81 e.printStackTrace(); 82 } 83 System.out.println("生成xml文件成功！！！"); 84 } 85 }
结果如图所示：
下面是用java解析上面所写的xml文件
简写版
package com.direct.demo;
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 Saxxml {
public static void main(String[] args) {
//解析xml文档
SAXBuilder builder = new SAXBuilder();
Document docu = null;
try {
docu = builder.build("e:/io/student.xml");
} catch (JDOMException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
Element root = docu.getRootElement();//得到根目录
List stulist = root.getChildren();
System.out.println(stulist.size()+"-----------");
System.out.println("------------------读取xml文档的信息---------------------");
for (int i = 0; i < stulist.size(); i++) {
Element e = (Element) stulist.get(i);
String stuid;
String stuname ;
String stusex ;
String stuage;
/*String stuValues = e.getAttribute("No").getValue();//属性值
String stuValues1 = e.getAttributeValue("No");
if (stuValues.equals("102")) {
//修改姓名
System.out.println(stuValues);
e.getChild("stuname").setText("砖石王老五");
//删除元素
root.removeContent(e);
break;
}*/
if (i==0) {
stuid = e.getChildText("stuid");
stuname = e.getChildText("stuname");
stusex = e.getChildText("stusex");
stuage = e.getChildText("stuage");
}else {
stuid = e.getChildText("stuid"+i);
stuname = e.getChildText("stuname"+i);
stusex = e.getChildText("stusex"+i);
stuage = e.getChildText("stuage"+i);
}
System.out.println("属性："+e.getAttributeValue("No"));
System.out.println("学号："+stuid);
System.out.println("姓名："+stuname);
System.out.println("年龄："+stuage);
System.out.println("性别："+stusex);
System.out.println("--------------------");
}
}
}
