Yes, these functions are exported from the xmerl_lib module (which is 
not documented, but it seems that it probably should be):

   expand_content/1, normalize_content/1,
   expand_element/1, normalize_element/1,

The difference between normalize and expand is that the normalize 
functions also flatten all text strings in the representation, which is 
useful when you want to search the tree for specific strings.
