Java语言实现XML美化功能
代码如下：
package tools;
import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.DOMConfiguration;
import org.w3c.dom.Document;
import org.w3c.dom.bootstrap.DOMImplementationRegistry;
import org.w3c.dom.ls.DOMImplementationLS;
import org.w3c.dom.ls.LSOutput;
import org.w3c.dom.ls.LSSerializer;
/**

*
* @author Tsybius2014

*/
public class XmlFormatTool {
/** 被美化XML文件的地址 */
public static String INPUT_FILE_PATH = "C:\\Users\\Tsybius2014\\Desktop\\input.xml";
/** 美化后XML文件的地址 */
public static String OUTPUT_FILE_PATH = "C:\\Users\\Tsybius2014\\Desktop\\output.xml";
/**
* XML格式美化工具
*
* @param args
* 参数列表
*/
public static void main(String[] args) {
FileInputStream fileInputStream = null;
FileOutputStream fileOutputStream = null;
try {
fileInputStream = new FileInputStream(INPUT_FILE_PATH);
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
Document document = documentBuilder.parse(fileInputStream);
DOMImplementationRegistry domImplementationRegistry = DOMImplementationRegistry.newInstance();
DOMImplementationLS domImplementationLS = (DOMImplementationLS) domImplementationRegistry
.getDOMImplementation("XML 3.0");
LSSerializer lsSerializer = domImplementationLS.createLSSerializer();
DOMConfiguration domConfiguration = lsSerializer.getDomConfig();
boolean isSupport = domConfiguration.canSetParameter("format-pretty-print", true);
if (isSupport) {
domConfiguration.setParameter("format-pretty-print", true);
}
LSOutput lsOutput = domImplementationLS.createLSOutput();
lsOutput.setEncoding("UTF-8");
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
lsOutput.setByteStream(byteArrayOutputStream);
lsSerializer.write(document, lsOutput);
byte[] data = byteArrayOutputStream.toByteArray();
File outputFile = new File(OUTPUT_FILE_PATH);
if (!outputFile.exists()) {
outputFile.createNewFile();
}
fileOutputStream = new FileOutputStream(outputFile);
fileOutputStream.write(data);
System.out.println("文件已生成：" + outputFile.getAbsolutePath());
} catch (Exception e) {
System.out.println("异常：" + e.getMessage());
} finally {
if (fileInputStream != null) {
try {
fileInputStream.close();
} catch (IOException e) {
System.out.println("fileInputStream关闭失败：" + e.getMessage());
}
}
if (fileOutputStream != null) {
try {
fileOutputStream.close();
} catch (IOException e) {
System.out.println("fileOutputStream关闭失败：" + e.getMessage());
}
}
}
}
}
美化前文件：
美化后文件：
END
