Simplest way to transform XML to HTML with XSLT in C#?
提问by Shaul Behr
XSLT newbie question: Please fill in the blank in the C# code fragment below:
XSLT 新手问题：请填写下面 C# 代码片段中的空白：
public static string TransformXMLToHTML(string inputXml, string xsltString) {
// insert code here to apply the transform specified by xsltString to inputXml
// and return the resultant HTML string.
// You may assume that the xslt output type is HTML.
}
Thanks!
谢谢！

How about:
怎么样：
public static string TransformXMLToHTML(string inputXml, string xsltString)
{
XslCompiledTransform transform = new XslCompiledTransform();
using(XmlReader reader = XmlReader.Create(new StringReader(xsltString))) {
transform.Load(reader);
}
StringWriter results = new StringWriter();
using(XmlReader reader = XmlReader.Create(new StringReader(inputXml))) {
transform.Transform(reader, null, results);
}
return results.ToString();
}
Note that ideally you would cache and re-use the XslCompiledTransform- or perhaps use XslTransforminstead (it is marked as deprecated, though).
请注意，理想情况下，您将缓存并重新使用XslCompiledTransform- 或者可能使用XslTransform它（尽管它被标记为已弃用）。

Just for fun, a slightly less elegant version that implements the caching suggested by Marc:
只是为了好玩，一个稍微不那么优雅的版本，它实现了 Marc 建议的缓存：
public static string TransformXMLToHTML(string inputXml, string xsltString)
{
XslCompiledTransform transform = GetAndCacheTransform(xsltString);
StringWriter results = new StringWriter();
using (XmlReader reader = XmlReader.Create(new StringReader(inputXml)))
{
transform.Transform(reader, null, results);
}
return results.ToString();
}
private static Dictionary<String, XslCompiledTransform> cachedTransforms = new Dictionary<string, XslCompiledTransform>();
private static XslCompiledTransform GetAndCacheTransform(String xslt)
{
XslCompiledTransform transform;
if (!cachedTransforms.TryGetValue(xslt, out transform))
{
transform = new XslCompiledTransform();
using (XmlReader reader = XmlReader.Create(new StringReader(xslt)))
{
transform.Load(reader);
}
cachedTransforms.Add(xslt, transform);
}
return transform;
}
