通过 xslt 使用从 xml 到文本文件的转换时抛出异常

Question

我的代码如下所示：

  protected String[] parseXMLRecievedMsg(StringBuffer iSB_plainMessage) throws Exception {

    Source xslt = new StreamSource(new File("sample.xslt"));
    TransformerFactory transFact = TransformerFactory.newInstance();
    Transformer transformer = transFact.newTransformer(xslt);
    StringWriter outWriter = new StringWriter();
    StreamResult lS_outputMsgBody = new StreamResult( outWriter );
    iSB_plainMessage =iSB_plainMessage.delete(0,iSB_plainMessage.indexOf("\n"));
    iSB_plainMessage =iSB_plainMessage.reverse();
    iSB_plainMessage =iSB_plainMessage.delete(0, iSB_plainMessage.indexOf("\n"));
    iSB_plainMessage =iSB_plainMessage.reverse();
    StringBuilder SB_plainMessage = new StringBuilder(iSB_plainMessage.toString());
    SB_plainMessage.insert(0,"<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r");

    Source lSB_MessageInput = new StreamSource(SB_plainMessage.toString());
    transformer.setOutputProperty(OutputKeys.METHOD, "text");
    transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");




    transformer.transform(lSB_MessageInput, lS_outputMsgBody);

    return new String []{ lS_outputMsgBody.getWriter().toString()};

我正在尝试将收到的 xml 消息转换为文本文件。我一直收到以下异常

采用 String (https://docs.oracle.com/javase/8/docs/api/javax/xml/transform/stream/StreamSource.html#StreamSource-java.lang.String-) 的 StreamSource 构造函数的重载期望带有 URI 的 String 而您似乎传入带有一些 XML 即时构建。如果你想用 XML 读取 String，那么在 String.

的 StringReader 上构造一个 StreamSource
