"None" result at Parsing XML with ElementTree

Question

I've tried everything to get a XML content but all I've got is a 'None' as return. Could anybody help me?

The code I'm trying is:

import xml.etree.cElementTree as ET

parsedXML = ET.parse("C:\\Users\\denis\\Documents\\Projetos\\NFe\\Arquivos\\33180601279711000100550020001554261733208443-nfeo.xml")


for node in parsedXML.getroot():
    email = node.find('cNF')
    phone = node.find('natOp')
    street = node.find('nNF')


print(email)

Part of the XML (content is bigger than this) is right bellow:

<?xml version="1.0" encoding="ISO-8859-1"?>
<nfeProc xmlns="http://www.portalfiscal.inf.br/nfe" versao="3.10">
<NFe xmlns="http://www.portalfiscal.inf.br/nfe">

</ide>
<emit>

I appreciate your help!

You are using an XML document with namespaces, so you need to provide it during you call, as shown in this answer.

Here, we get

namespaces = {'n': 'http://www.portalfiscal.inf.br/nfe'}
root = parsedXML.getroot()
root.find('n:NFe', namespaces)

to return the element, while root.find('NFe') returns None.

Also note that find and findall only search the direct children, not nested children (cf. documentation), which mean that you will have to iter over children (see e.g. here for an example).
