The sample of code I'm using for a project

test.py

from lxml import etree
from zeep import Plugin

class MyLoggingPlugin(Plugin):

    def ingress(self, envelope, http_headers, operation):
        print(etree.tostring(envelope, pretty_print=True))
        return envelope, http_headers

    def egress(self, envelope, http_headers, operation, binding_options):
        print(etree.tostring(envelope, pretty_print=True))
        return envelope, http_headers
