使用JDOM处理XML数据之XSLT篇(二)

   使用JDOM处理XML数据之XSLT篇(二)

 

我们用一个javabean来实现对XML文档的格式化。

XSLTFilter.java

package XML;             

      

import java.io.*;                      

import java.util.*;

import org.jdom.*;

import org.jdom.output.*;

import org.jdom.transform.*;

import javax.xml.transform.*;          

import javax.xml.transform.stream.*;   

 

public class XSLTFilter {       

     private   Document outputDoc;

     private   String stylesheetPath; 

     private   Document doc=null;

  public  XSLTFilter() {}

  public void setoutputDoc(Document s)  {

     this.outputDoc=s;

  }

 public void setStylePath(String s)  {

     this.stylesheetPath=s;

  }

  public void startFilter()  {

    try {

      TransformerFactory myFactory = TransformerFactory.newInstance();

      Transformer myTransformer = myFactory.newTransformer(new StreamSource(stylesheetPath));

 

      JDOMResult result = new JDOMResult();

      myTransformer.transform( new JDOMSource( outputDoc ), result );

      doc = result.getDocument();

     

    } catch (Exception e) {

      System.out.println("Error was:" + e.getMessage());

    }   

  }

  public void destroy() {}

  public Document getXmlDoc(){

    return(doc);

 }

}

这个javabean输入一个JDOM文档格式，输入一个XSLT文档的位置，输出格式化好的文档。

然后用一个jsp来调用这个javabean

<%@ page contentType="text/html; charset=gb2312" %>

<%@ page import="org.jdom.*" %>

<%@ page import="org.jdom.output.*"  %>

<%@ page import="org.jdom.input.*" %>

<%@ page import="java.io.*" %>

<%@ page import="java.util.*" %>

<%@ page import="XML.*" %>

<%

  String fileName="watchlist.xml";

  String aa=getServletContext().getRealPath("/")+"jdom\\";

  String trace=aa+fileName;

  String styleName="watchlist.xsl";

  String styleTrace=aa+styleName;

  String resultName="aa.html";

  String resultTrace=aa+resultName;

  XML.readXML readXmlBean  = new  XML.readXML(); 

  Document doc;

  readXmlBean.readXML(trace);

  doc=readXmlBean.getXmlDoc();

  XML.XSLTFilter XSLTFilter =new  XML.XSLTFilter();

  XSLTFilter.setoutputDoc(doc);

  XSLTFilter.setStylePath(styleTrace);

  XSLTFilter.startFilter();

  doc=XSLTFilter.getXmlDoc();

  XML.writeXML writeXmlBean  = new  XML.writeXML();

  writeXmlBean.writeXML(doc,resultTrace);

%>
