java 怎样解析 excel生成的xml文件

如题所述

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"

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();
}
}
}
