You can't.  XSLT sees the parsed representation of the XML document, not
the tagged text, so the '<', '</', '</' and '/>' markup isn't present.

You could write an extension function to walk a branch of the tree that
counts characters and compensates for the missing markup, but there is no
guarantee that serialization won't affect the amount of text that is
generated for a given subtree.

You can get the string value of a node, then get it's length, but that's
not what you're describing here.
