xml.etree.ElementTree >> Python >> How to access child element and make assertions

Question

I am using PyTest to validate xml api response. Getting following response(response.content) from api request

b'<?xml version="1.0" encoding="UTF-8"?>
<Result0>
<Result1>
<Result3>
<Id>2</Id>
<ItemId>https://purchanse.com/62/E00036415</ItemId>
<Place>kpi:62_CS415-TEN-1080p25-ABC</Place>
<Marks>12</Marks>
<SubId>9, 8</SubId>
<Description>https://purchanse.com/62/E00036416</Description>
</Result3>
<Result4>
<Id>2</Id>
<ItemId>https://purchanse.com/64/E00036417</ItemId>
<Place>kpi:63_CS415-TEN-1080p25-XYZ</Place>
<Marks>12</Marks>
<SubId>9</SubId>
<Description>https://purchanse.com/64/E00036416</Description>
</Result4>
</Result1>
</Result0>'

in test function I have this code

def test_CheckResponseContent():
    element = et.fromstring(response.content)
    print("element", element)  # Getting <Element 'Result0' at 0x04A88C58> as output
    links = element.find("Result0/Result1")
    print("L:", links)  # Returns 'None'

element = et.fromstring(response.content)
    for child in element.iter('*'):
        print(child.tag)

I want to make assertions like

Marks == 12
Id == 2
ItemId != "https://purchanse.com/62/E00036416"

How can I parse the XML for this?
Can someone please help

Answer 1

You have multiple tags with mentioned names, so the corresponding set of checks should be performed separately, for each parent of these tags.

To do it, try the following code, maybe without print statements:

for it in element.findall('Result1/*'):
    print(it.tag)
    mrks = it.findtext('Marks')
    id = it.findtext('Id')
    itmId = it.findtext('ItemId')
    print(mrks, id, itmId)
    assert mrks == '12'
    assert id == '2'
    assert itmId != 'https://purchanse.com/62/E00036416'
