Is there a way to determine which tags are actually being used in the template?

I have a fairly complex and large template and data mapper. I started this when I was first learning and now I want to clean up the data mapper and the template. I am using one data mapper for five templates. Is there a way to run something or mark the elements in my xml that I am actually using in my template so I can delete what is not being used?

Thanks

hello ahaddad,

There no native tools to identify the nodes that are in use.
