Findall using ElementTree does not return expected result

Navigation
0

I'm trying to find a specific element inside a python XML file. To do this, I use ElementTree.

The following code: 

    root = ET.fromstring(response.content.decode('utf-8'))
    print(root.findall('.//*'))

Give me the following table as a return:

I need to find out what the value of the element '{http://schemas.microsoft.com/exchange/services/2006/types}EmailAddress'

For this, I did the following: 

teste = root.findall('{http://schemas.microsoft.com/exchange/services/2006/types}EmailAddress')
print(teste)

From what I read, this should work without problems. But what is returned is an empty array. Does anyone have any idea what I'm doing wrong?

Look for the Tag attribute of each element, which will have the xml namespace and tag name. Hence, just verify that the tag has as substring EmailAddress and not EmailAddresses . If this happens, we find the TAG of the email and just extract the text. 

for el in root.findall('.//*'):
        if el.tag.find('EmailAddress') != -1 and el.tag.find('EmailAddresses') == -1 :
            print(el.text)

This solution: 

root.findall('{http://schemas.microsoft.com/exchange/services/2006/types}EmailAddress')

It will not work because EmailAddress is not a child element of root . You would need to put all namespaces and tags until you get EmailAddress for this method to work.
