Getting started

The following model fields binding:

    launched: Optional[int] = attr(default=None)  # extracted from the 'launched' attribute
    title: str  # extracted from the element text


class Company(BaseXmlModel):
    trade_name: str = attr(name='trade-name')  # extracted from the 'trade-name' attribute

    products: List[Product] = element(tag='product', default=[])  # extracted from the 'Company' element's children
