以下代码用于将XML文档转换为HTML文档：
XslTransform vXslTransform = new XslTransform();
XmlReader vReader = new XmlTextReader(new StringReader(this.Xslt));
vXslTransform.Load(vReader,null as XmlResolver, null as System.Security.Policy.Evidence);
StringWriter vStringWriter = new StringWriter();
vXslTransform.Transform(this.XmlDocument, null, vStringWriter, null);
此代码已经使用多年了。然后我来了，我想要做的就是添加一个URL到混合。您可以在下面的XML中看到新的URL（CoreReturnLabel元素）：
<CoreReturnEmail>
<CoreReturnLabel>https://www.example.com/SomePage.pdf?token=eaf5383bddb9382f5&createdby=f01ddedb0aedd87fe44b9b9b741</CoreReturnLabel>

正如您所看到的，这非常有效。 CoreReturnLabel URL显示在在线XSL转换以及NotePad ++的XSL转换中。但是，它通过初始代码的那一刻：
XslTransform vXslTransform = new XslTransform();
XmlReader vReader = new XmlTextReader(new StringReader(this.Xslt));
vXslTransform.Load(vReader,null as XmlResolver, null as System.Security.Policy.Evidence);
StringWriter vStringWriter = new StringWriter();
vXslTransform.Transform(this.XmlDocument, null, vStringWriter, null);
...网址为空。
为什么？
答案 0 :(得分：0)
对不起我没有将运行Transform的最新应用程序部署到服务器。当我这样做时，这很好用。
因此，原来的问题实际上是正确答案。
