Hope this helps Don't use Regex for any XML parsing!
Using XDocument will suffice here:
code :
var html = XDocument.Parse(htmlString);
var spanElements = html.Descendants("span").ToList(); 
for (int i = spanElements.Count - 1; i >= 0; i--)
    if (spanElements[i].Value == "") spanElements[i].Remove();
