Dom4j工具类源码解析

话不多说，上源码：

package com.changeyd.utils;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.UnsupportedEncodingException;

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

public class Dom4jUtils {

public static final String PATH = "src/p1.xml";

// 返回document
public static Document getDocument(String path) {

try {
// 创建解析器
SAXReader saxReader = new SAXReader();

// 得到document
Document document = saxReader.read(path);
return document;
} catch (DocumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;

}

// 回写xml的方法
public static void xmlWriters(String path, Document document) {
XMLWriter xmlWriter = null;
try {
OutputFormat format = OutputFormat.createPrettyPrint();
xmlWriter = new XMLWriter(new FileOutputStream(path), format);
try {
xmlWriter.write(document);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
try {
xmlWriter.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

}

}

代码简单，供忘记的人复习
