As HtmlAgilityPack is yet not supported in windows phone 8.1,referencing manually in the project was a trick solution. But this is not the only problem. I could use XP

    If you meant to translate your current code which using XPath to be using LINQ, then this will do :

    HtmlNode parent = document.DocumentNode
                          .Descendants("ul")
                          .FirstOrDefault(o => o.GetAttributeValue("class", "") 
                                                   == "songs-list1")
HtmlNodeCollection x = parent.ChildNodes;

    But if you expect to find methods that accept XPath in HtmlAgilityPack version for Windows Phone 8.1 universal apps or Windows RT ("I'm seeking for a block of code which will work like SelectNodes, SelectNode"), you better don't : HtmlAgilityPack & Windows 8 Metro Apps (answer by the author of HAP).

    You can do it using the Element/s method:

            HtmlDocument doc = new HtmlDocument();
        doc.LoadHtml(htmlString);
        var h6Nodes = from h6element in doc.DocumentNode.Element("body").Element("center").Elements("h6")
                      where h6element.Attributes["class"].Value.Equals("songs-list")                      
                      select h6element;

    This is assuming you have something like

    string htmlString = @"<html>
<body>
<center>
<h6>Hello  </h6>
<h6>World!   </h6>
<h6 class=""songs-list"">
Insert that one song here
</h6>
</center>
</body>
</html>"

    and that will get the <h6> node with class songs-list.
