from ninja.parser import JSONParser, FormParser

api = NinjaAPI()

@api.post("/json/", parser=JSONParser())
def handle_json(request, data: dict):
    return {"received_data": data}

@api.post("/form/", parser=FormParser())
def handle_form(request, name: str, age: int):
    return {"name": name, "age": age}

from ninja.parser import Parser
from lxml import etree

class XMLParser(Parser):
    def parse_body(self, request):
        body = request.body.decode()
        root = etree.fromstring(body)
        return {child.tag: child.text for child in root}

from ninja import NinjaAPI
