dom4j学习笔记[3]---获取、修改XML元素

1. 遍历笔记[1]中生成的xml文件，并对其进行修改，代码如下：

import java.io.IOException;
import java.io.File;
import java.util.Iterator;
import java.util.List;
import org.dom4j.io.OutputFormat;
import org.dom4j.io.XMLWriter;
import org.dom4j.io.SAXReader;
import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.Node;
import org.dom4j.Element;
import org.dom4j.io.OutputFormat;
import org.dom4j.Attribute;

public class Parse_2 {

public Document parse(String sfile) throws DocumentException {
SAXReader reader = new SAXReader();
Document document = reader.read(new File(sfile));
return document;
}

public void bar(Document document) throws IOException {

List list = document.selectNodes( "//author" );
Iterator iter=list.iterator();

System.out.println("/r/n****** 获取的数据如下 ******");
while(iter.hasNext()){
Element titleElement=(Element)iter.next();
// 修改xml元素
if(titleElement.getText().equals("James Strachan")) {
titleElement.setText("Faint Heipark");
}
System.out.print(titleElement.valueOf( "@name" ) + "：");
System.out.println(titleElement.getText());
}

// 输出全部原始数据
OutputFormat format = OutputFormat.createPrettyPrint();
XMLWriter writer = new XMLWriter( System.out, format );
System.out.println("/r/n------------------Start------------------");
writer.write( document );
System.out.println("/r/n-------------------End-------------------");
}

public static void main(String[] args) {
Parse_2 dom4j = new Parse_2();
try {
dom4j.bar(dom4j.parse("c://output.xml"));

} catch (Exception e) {
System.out.println(e.getMessage());
}
}
}
