PydanticXML

PydanticXML is a Python library that provides a way to convert Pydantic models to XML and vice versa. It is built on top of the Pydantic library and extends it with XML-specific functionality.

Installation

You can install PydanticXML with pip:

pip install pydantic-xmlmodel

Usage

To use PydanticXML, you need to import the XMLModel class from the pydanticxml module:

from pydantic_xmlmodel import XMLModel

Here is the class diagram of the library:

Examples

Defining a Model

You can define a model by subclassing XMLModel and defining attributes with type annotations:

class AnimalCharacteristics(XMLModel):
    color: str = "black"
    weight: int = 10
    is_friendly: bool = True

Converting a Model to XML

You can convert a model to XML by calling the dicttoxml() method:

class Cat(XMLModel):
    animal_characteristics: AnimalCharacteristics
    name: str = "Kitty"

cat = Cat(animal_characteristics=AnimalCharacteristics())
print(cat.dicttoxml(indent=4))

This will output:

<?xml version="1.0" ?>
<cat name="Kitty">
    <animalcharacteristics color="black" weight="10" is_friendly="True"/>
</cat>

Converting XML to a Model

You can convert XML to a model by calling the fromxml() method:

xml = """<?xml version="1.0" ?>
<cat name="Kitty">
    <animalcharacteristics color="black" is_friendly="true" weight="10"/>
</cat>
"""
cat = Cat.fromxml(xml)
print(cat)

This will output:

animal_characteristics=AnimalCharacteristics(color='black', weight=10, is_friendly=True, __xml_content__=None) name='Kitty' __xml_content__='\n    '

(Note that the __xml_content__ attribute is not part of the model. It is used to store the XML content, like this <element> xml_content <other_element /></element>)
