[analista01]

In the example (https://www.fastht.ml/docs/tutorials/by_example.html):

class Person:
def init(self, name, age):
self.name = name
self.age = age

def __ft__(self):
    return ['div', [f'{self.name} is {self.age} years old.'], {}]

p = Person('Jonathan', 28)
print(to_xml(Div(p, "more text", cls="container")))

Output not render the tag "div", show:

['div', ['Jonathan is 28 years old.'], {}]more text
