I am not completely sure of the context of the thread but to avoid
confusion...
anyhelper.xml() is the same as str(anyhelper) is serialize the
anyhelper in HTML not in XML, as the name suggests.
FORM and SQLFORM are no exception. The operator can be overloaded
class MYFORM(FORM):
def xml(self):
return FORM.xml(self)
and you can also redefine the class: FORM=MYFORM.
