C# HtmlAgilityPack能否处理xsl文件附带的xml文件来呈现html？

C# HtmlAgilityPack能否处理xsl文件附带的xml文件来呈现html？,c#,html-agility-pack,C#,Html Agility Pack,我想知道HtmlAgilityPack读取包含xsl文件以呈现html的xml文件的最佳方法。HtmlDocument类上是否有任何设置可以帮助实现这一点，或者在使用HtmlAliyPack加载转换之前，我是否必须找到执行转换的方法？如果对后者是肯定的，有谁知道这样一个转换的好库或方法？下面是一个网站的示例，它返回带有xls文件的xml以及我想使用的代码 var uri = new Uri("http://www.skechers.com/"); var request = (HttpWebRe

我想知道HtmlAgilityPack读取包含xsl文件以呈现html的xml文件的最佳方法。HtmlDocument类上是否有任何设置可以帮助实现这一点，或者在使用HtmlAliyPack加载转换之前，我是否必须找到执行转换的方法？如果对后者是肯定的，有谁知道这样一个转换的好库或方法？下面是一个网站的示例，它返回带有xls文件的xml以及我想使用的代码

var uri = new Uri("http://www.skechers.com/");
var request = (HttpWebRequest)WebRequest.Create(url);
var cookieContainer = new CookieContainer();

request.CookieContainer = cookieContainer;
request.UserAgent = @"Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5";
request.Method = "GET";
request.AllowAutoRedirect = true;
request.Timeout = 15000;

var response = (HttpWebResponse)request.GetResponse();
var page = new HtmlDocument();
page.OptionReadEncoding = false;
var stream = response.GetResponseStream();
page.Load(stream);

这段代码不会抛出任何错误，但xml是解析的内容，而不是转换，这正是我想要的。

您应该呈现xml和XSLT的输出。要做到这一点，您需要下载XML，而且您已经下载了。接下来解析XML以标识XSL引用。然后需要下载XSL并将其应用于XML文档

var xmlStream = response.GetResponseStream();
var xmlDocument = new XPathDocument(xmlStream);
var styleNode = xmlDocument.CreateNavigator().SelectSingleNode("processing-instruction('xml-stylesheet')");
var hrefValue = Regex.Match((styleNode).Value, "href=(\"|')(?<url>.*?)(\"|')");
if(hrefValue.Success)
{
    var xslHref = FormAssetSrc(hrefValue.Groups["url"].Value, response.ResponseUri);
    var xslUri = new Uri(xslHref);
    var xslRequest = CreateWebRequest(xslUri);
    var xslResponse = (HttpWebResponse)xslRequest.GetResponse();
    var xslStream = new XPathDocument(xslResponse.GetResponseStream());
    var xslTransorm = new XslTransform();
    var sw = new System.IO.StringWriter();
    xslTransorm.Load(xslStream);
    xslTransorm.Transform(xmlDocument.CreateNavigator(), null, sw);
    page.Html.LoadHtml(sw.ToString());
}

var xmlStream=response.GetResponseStream（）；
var xmlDocument=新的XPathDocument（xmlStream）；
