I hope it can not be done like

• You should do a sanity check over what you are doing. If you want to pass objects/information round as strings, you can easily serialize/deserialize between objects and XML. Here, most of the work is done for you
• If you can't change the format, and you have a limited number (e.g. 10 or so) of inbound types, just implement a simple if statetment.
• If you have more types to deal with, you'll need to do the work by reflection. Reflection takes much more code and is relatively messy.

finally 
{
   xmlDoc = null;
}
