这篇文章主要介绍了java实现的xml格式化实现代码,需要的朋友可以参考下

核心代码：

java" id="highlighter_149516">

									package com.ddatsh;

									import java.io.IOException;

									import java.io.StringReader;

									import java.io.StringWriter;

									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 XmlFormat {

									  public static String format(String str) throws Exception {

									    SAXReader reader = new SAXReader();

									    // System.out.println(reader);

									    // 注释：创建一个串的字符输入流

									    StringReader in = new StringReader(str);

									    Document doc = reader.read(in);

									    // System.out.println(doc.getRootElement());

									    // 注释：创建输出格式

									    OutputFormat formater = OutputFormat.createPrettyPrint();

									    //formater=OutputFormat.createCompactFormat();

									    // 注释：设置xml的输出编码

									    formater.setEncoding("utf-8");

									    // 注释：创建输出(目标)

									    StringWriter out = new StringWriter();

									    // 注释：创建输出流

									    XMLWriter writer = new XMLWriter(out, formater);

									    // 注释：输出格式化的串到目标中，执行后。格式化后的串保存在out中。

									    writer.write(doc);

									    writer.close();

									    System.out.println(out.toString());

									    // 注释：返回我们格式化后的结果

									    return out.toString();

									  }

									  public static void main(String[] args) throws Exception {

									    String head="<?xml version=\"1.0\" encoding=\"GBK\"?>";

									    String str = "<RequestData><HeadData><UserCode>sh1_admin</UserCode><UserName>sh1_admin</UserName><UserCompanyCode>3107</UserCompanyCode><UserCompanyName>上海分公司一部</UserCompanyName><RequestType>03</RequestType></HeadData><BodyData><ReportId>113100000033</ReportId><Insurant>a5rfg87</Insurant><NumberPlate>沪E78612</NumberPlate><EngineModel></EngineModel><CarVin></CarVin><AccidentDate>2011-02-25 15:07:00</AccidentDate><ReportDate>2011-02-25 15:07:00</ReportDate><Province>310000</Province><City>310100</City><District></District><AccidentPlace>1</AccidentPlace><AccidentLongitude></AccidentLongitude><AccidentLatitude></AccidentLatitude><SurveyLongitude></SurveyLongitude><SurveyLatitude></SurveyLatitude><SceneReportFlag></SceneReportFlag><Reporter></Reporter><ReporterTel></ReporterTel><SurveyPlace></SurveyPlace><OperatorId>3525</OperatorId><OperatorName>sh_admin</OperatorName><ReportDealId>30000800</ReportDealId><ReportDealName>江苏分公司</ReportDealName><CompanyName></CompanyName><CustomerTypeCode></CustomerTypeCode><ForcePolicyId>a5rfg87a5rfg87a5rfg87</ForcePolicyId><BizPolicyId></BizPolicyId><Index>0</Index><FieldName>5</FieldName></BodyData></RequestData>";

									    // System.out.println(str);

									    format(str);
