I made a simple program for fetching youtube users in comments. This is the code
string html;
using (var client = new WebClient())
{
html = client.DownloadString("http://www.youtube.com/watch?v=ER5EnjskCvE");
}
HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml(html);
List<string> data = new List<string>();
HtmlNodeCollection nodeCollection = doc.DocumentNode.SelectNodes("//*[@id='comments-view']/ul[1]/li[1]/a/span/span/span/span/img");
foreach (HtmlNode node in nodeCollection)
{
data.Add(node.GetAttributeValue("alt",null));
}
But i have a problem that my nodeCollection is returning null. For the XPath i used copy XPath option in chrome under F12
try this replace "*" , "div"
"/html/body//div[@id='comments-view']/ul[1]/li[1]/a/span/span/span/span/img"
