java - 在 Java 中使用 XSLT 将 XML 转换为 HTML 字符串

Question

我现在可以使用以下代码生成 HTML 文件:

FileInputStream xml = new FileInputStream("original.xml");  
FileInputStream xsl = new FileInputStream("converter.xsl");
FileOutputStream out = new FileOutputStream("result.html");

Source xmlDoc =  new StreamSource(xml);
Source xslDoc =  new StreamSource(xsl);
Result result =  new StreamResult(out);

TransformerFactory factory = TransformerFactory.newInstance();            
Transformer trans = factory.newTransformer(xslDoc);
trans.transform(xmlDoc, result); 

但是，我想生成一个 Java 字符串而不是外部 HTML 文件，以便我可以通过 Ajax 回调将结果传递回我的 JSP 页面。我怎样才能修改这段代码来做到这一点？

Answer 1

将 FileOutputStream 替换为 StringWriter，然后在最后调用 StringWriter 上的 toString()。像这样的东西。

FileInputStream xml = new FileInputStream("original.xml");  
FileInputStream xsl = new FileInputStream("converter.xsl");
StringWriter writer = new StringWriter();

Source xmlDoc =  new StreamSource(xml);
Source xslDoc =  new StreamSource(xsl);
Result result =  new StreamResult(writer);

TransformerFactory factory = TransformerFactory.newInstance();            
Transformer trans = factory.newTransformer(xslDoc);
trans.transform(xmlDoc, result); 

String outputString = writer.toString();
