I am trying to convert some JSON data into XML in Python using the Pydantic-XML library (https://pydantic-xml.readthedocs.io/en/latest/index.html). However, I am having trouble getting the default namespaces according to my business requirements. This is my code: class Socials( BaseXmlModel, tag='socials', nsmap={'': 'http://www.company.com/soc'}, ): urls: List[str] = element(tag='social') class Contacts( BaseXmlModel, tag='contacts', nsmap={'': 'http://www.company.com/cnt'}, ): socials: Socials = element() class Company( BaseXmlModel, tag='company', nsmap={'': 'http://www.company.com/co'}, ): contacts: Contacts = element() My desired output: (requirement from business, ns starts from 1 not 0) <ns1:company xmlns:ns1="http://www.company.com/co" xmlns:ns2="http://www.company.com/cnt" xmlns:ns3="http://www.company.com/soc"> <ns2:contacts> <ns3:socials> <ns3:social>https://www.linkedin.com/company/spacex</ns2:social> <ns3:social>https://twitter.com/spacex</ns2:social> <ns3:social>https://www.youtube.com/spacex</ns2:social> </ns3:socials> </ns2:contacts> </ns1:company> What I get from library: <company xmlns="http://www.company.com/co"> <contacts xmlns="http://www.company.com/cnt" > <socials xmlns="http://www.company.com/soc"> <social>https://www.linkedin.com/company/spacex</social> <social>https://twitter.com/spacex</social> <social>https://www.youtube.com/spacex</social> </socials> </contacts> </company> Can anyone help let me know how to achieve this with the pydantic-xml library or any other python library?
