c# - Select elements with attribute data-url using HTMLAgilityPack -


I'm writing a little bit of download-robot, which is looking for links in the lower layers

I can find all the links in an HTML page (links to .pgn, .pdf, .html, .... as well as links to .jpg files) - files

I have all one- I'm using HTML-agilitypack to find href links.

Sample code: 

  foreach (html.document link html.document.DocumentNode.SelectNodes ("// a [@heref] ")) {HTMLtml attribute = link.Attributes [" href "]; Links.Add (attribute.Value); }   
 But I have to get the data-url I  
 What XPath-syntax I want to use to find the data-url is an example data-url in i html code :  
  & lt; Div class = "cbreplay" data-url = "2012 \ edmonton \ partien.pgn" & gt; & Lt; / Div & gt; I need "2012 \ edmonton \ partien.pgn" from this example. How can I feel it with XPath syntax?  
 Good luck, if I made some bad mistakes, then tell me. This is my first question.   
 
 
 The following should do you:  
  foreach (html.dode divNode in htmlDocument .DocumentNode.SelectNodes ("// div [@ data-url]") {HTML attribute attribute = divNode.Attributes ["data-url"]; Links.Add (attribute.Value); }   
 Effectively, the statement  // div [@ data-url]  should select all the nodes with the data-url attribute. We then drag this feature.  
 If this feature has nodes other than divs, then  // * [@ data-url]  should be tricked.
