xml＋xsl生成html的方法

今天在论坛上看到一位朋友在利用xml＋xsl生成html的时候，出现了乱码，在他代码的基础上做了下修改，解决了乱码问题。不知道是不是利用这种方法只能生成UTF-8的格式。

后来发现有include文件的情况，修改代码如下。

        throws Exception {  
 
 
 
    DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory  
 
 
 
    .newInstance();  
 
 
 
    DocumentBuilder builder = docBuilderFactory.newDocumentBuilder();  
 
 
 
    Document xmlDoc = builder.parse(new InputSource(new StringReader(xml)));  
 
 
 
    Source xmlSource = new DOMSource(xmlDoc);  
 
 
 
    StreamSource xslSource = new StreamSource(new StringReader(xsl));  
 
 
 
    TransformerFactory tf = TransformerFactory.newInstance();  
 
    URIResolver uriReslover = new URIResolver() {  
 
        public Source resolve(String href, String base)  
 
                throws TransformerException {  
 
            try {  
 
                //当遇到include文件的时候会执行此方法  
 
                // return new StreamSource(new StringReader(

                return null;  
 
            } catch (IOException e) {  
 
                e.printStackTrace();  
 
            }  
 
            return null;  
 
        }  
 
    };  
 
    tf.setURIResolver(uriReslover);  
 
    Templates transformation = tf.newTemplates(xslSource);
