XmlSerializer vs BinaryFormatter

XmlDocument doc = new XmlDocument();
string type = RegEx.Match(list.GetType().ToString(), "\[\w+\]").Value;
doc.LoadXml("<list type='"+type+"'></list>");
foreach(var v in list)
{   
    doc.DocumentElement.InsertAfter(GetXmlElement(v), doc.DocumentElement.LastChild);
