Question

我们将数据作为XML，并且有多种格式化的XSL样式。它在IE中工作得很好。

然后，我们需要在Chrome中显示与HTML相同的内容。因此，我们在服务器端（Java）找到了一个API，用于将XML + XSL转换为HTML。

public static String convertXMLXSL(String xml, String xsl) throws SQLException {
        System.setProperty("javax.xml.transform.TransformerFactory", "org.apache.xalan.processor.TransformerFactoryImpl");
        TransformerFactory tFactory = TransformerFactory.newInstance();

        String html = "";

        try {
            try {
                StreamResult result = new StreamResult(new StringWriter());
                **Transformer trans = tFactory.newTransformer(new StreamSource(new ByteArrayInputStream(xsl.getBytes("utf-8"))));
                trans.transform(new StreamSource(new ByteArrayInputStream(xml.getBytes("utf-8"))), result);**
                html = result.getWriter().toString();
            } catch (TransformerException te) {
                te.printStackTrace();
            }
        } catch (Exception e) {
            AppendExceptionToLog(e);
        }
        return html;
    }

但是，过了一段时间之后，我们看到一些线程转储在 javax.xml.transform.Transformer

的 trasform 方法中被阻止

在这里，我想知道..

1）我们是否有任何其他已知的实现在服务器端执行相同的操作？

2）我是否应该考虑使用Mozilla的 XSLTProcessor 来使用客户端方法？

使用Java在HTML中转换XML + XSL
