对.net中<U></U>值的html文件进行简单解析?

正则表达式:

Dim myPattern As String = "<U>(.*?)</U>"

    For Each thisMatch As Match In System.Text.RegularExpressions.Regex.Matches(myPage1HTML, myPattern,RegexOptions.IgnoreCase)
            Response.write(thisMatch.ToString)
    Next

XmlNodeList list = doc.SelectNodes("//u");

给你一份 U 节点

XmlDocument doc = new XmlDocument();
doc.Load("file.html");

XmlNodeList nodeList = doc.DocumentElement.SelectNodes("//u");
foreach (XmlNode title in nodeList) {
    Console.WriteLine(title.InnerXml);
}

它取自 here

如果HTML文档格式正确,XPath将是我的首选。

请求的代码示例(从未测试过);

var doc                    = new XPathDocument (@"path\to\file.html");
XPathNavigator navigator   = doc.CreateNavigator ();
XPathNodeIterator iterator = navigator.Select ("//U");
while (iterator.MoveNext ())
    Console.WriteLine ("U: {0}", iterator.Current.Value);
