使用Saxon-HE对JavaFX中的xml文件进行XSLT转换

我正在构建一个小型应用程序，我打开一个XML文件并将其显示在JavaFX中的TextArea中。然后我调用一个方法指向本地的XSL文件，该文件执行转换为简单的HTML输出。最后，我想将转换后的XML显示到一个新的弹出窗口中（加载另一个.fxml文件）。使用Saxon-HE对JavaFX中的xml文件进行XSLT转换

所以我有一个RootLayout.fxml和处理变换调用各自的RootLayoutController。 RootLayout很简单，只处理菜单操作（打开文件，转换）并启动另一个FXML。 textarea里包含在这个其他FXML文件editorOverview：

@FXML 
private void handleTransform() { 
    String xslt = "main.xsl"; // the path is reduced only here for simplicity 
    String source = src.MainApp.editorOverviewController.XMLtextArea.getText(); 
    String result = ""; 
    TransformerFactory tFactory = TransformerFactory.newInstance(); 
    try {  
     Transformer transformer = tFactory.newTransformer(new StreamSource(new File(xslt))); 
     transformer.transform(new StreamSource(new StringBufferInputStream(source)), new StreamResult(result)); 

     src.MainApp.TransformViewController.resultTextArea.setText(result); 
     src.MainApp.TransformViewController.showResult(); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
}

所以我想分配变换为空字符串result的结果，然后将文本区域在TransformView.fxml文本设置的值`结果。之后，我想展示这个窗口。

在我TransformViewController我有showResult()方法：

public void showResult() { 
    try { 
     FXMLLoader loader = new FXMLLoader(getClass().getResource("TransformView.fxml")); 
     Parent htmlView = (Parent) loader.load(); 
     Stage stage = new Stage(); 
     stage.setTitle("HTML Result"); 
     stage.setScene(new Scene(htmlView)); 
     stage.show(); 
    } catch (IOException ex) { 
     Logger.getLogger(TransformViewController.class.getName()).log(Level.SEVERE, null, ex); 
    } 
}

的问题是，我得到以下错误：

java.io.FileNotFoundException: (Access is denied) 
; SystemID: 
net.sf.saxon.trans.XPathException: java.io.FileNotFoundException: (Access is denied)

是与我做的改造方式的错误？（为了记录，这个转换在带有Saxon-HE 9.5的oXygen XML Developer中成功执行，与我的项目中包含的jar一样）

任何想法/建议都非常感谢！

堆栈跟踪会告诉你程序中的错误来自哪一行。这是我们需要知道的第一件事情，以帮助您进行调试。 – 2014-10-29 09:19:21

谢谢，我更新了整个堆栈跟踪的问题。令我感到困惑的是，最重要的是它说xslt文件存在错误。但与此同时，当我对同一个saxon-9.5.1.5版本的项目之外的同一个xml文件执行完全相同的xslt时，我没有遇到任何错误。这就是为什么我可能会在变压器本身出现问题。 – lapadets 2014-10-29 11:23:04

您的应用程序是否有权访问文件系统？结帐：http：//stackoverflow.com/q/11882586/241294。 – poida 2014-10-29 12:12:36

为了获得变换为字符串的结果，执行

StringWriter sw = new StringWriter(); 
StreamResult result = new StreamResult(sw);

指定result作为转化的目的地（第二参数为transform()），完成后，sw.toString()将包含序列化转换结果。
