Can I somehow skip every third element using linq, starting at 1? those. 1, 4, 7 ...
There is such a sample, but you need to remove elements from it:
var links = doc.DocumentNode.SelectNodes("//table[@class='xml-feed-table']")[0].Descendants("tr") .Select(tr => tr.Elements("td").Select(td=> td.InnerHtml).ToList()).Skip(8).ToList();
