That's because there are TextNodes in the Html that have no text. Fixing that is rather easy though, you just have to filter the empty text.

Like so:

 string x = String.Join(",", doc.DocumentNode
    .SelectNodes("//h4").Elements()
    .Select(el => el.InnerText)
    .Where(text => !string.IsNullOrWhiteSpace(text)));

If you want something like that for the whole page, i posted something similiar here.
