Remove empty tags from xml document

By using regular expression we can remove empty tags from xml document.

 
 Regex regex = new Regex(@"(\s)*<(\w:\w|\w)*(\s)*/>");
 string xml= regex.Replace(xml, string.Empty);

We can also use LINQ to XML as follows

 XDocument doc = XDocument.Parse(xml);
 doc.Descendants().Where(d => !d.DescendantNodes().OfType().Any(t => t.Value.Trim() != "")).Remove();
return doc.ToString();
