Hello I am making a requests call to return order data from a online store. My issue is that once I have passed my data to a root variable the method iter is not returning the correct results. eg Display multiple tags of the same name rather than one and not showing the data within the tag.
I thought this was due to the XML not being correctly formatted so I formatted it by saving it to a file using pretty_print
but that hasn't fixed the error.
How do I fix this? - Thanks in advance
Code:
import requests, xml.etree.ElementTree as ET, lxml.etree as etree
url="http://publicapi.ekmpowershop24.com/v1.1/publicapi.asmx"
headers = {'content-type': 'application/soap+xml'}
body = """<?xml version="1.0" encoding="utf-8"?>

#send request to ekm
r = requests.post(url,data=body,headers=headers)
#save output to file

file.write(r.text)
file.close()
#take the file and format the xml
x = etree.parse("C:/Users/Mark/Desktop/test.xml")
newString = etree.tostring(x, pretty_print=True)
file = open("C:/Users/Mark/Desktop/test.xml", "w")
file.write(newString.decode('utf-8'))
file.close()
#parse the file to get the roots
tree = ET.parse("C:/Users/Mark/Desktop/test.xml")
root = tree.getroot()
#access elements names in the data
for child in root.iter('*'):
print(child.tag)
#show orders elements attributes
tree = ET.parse("C:/Users/Mark/Desktop/test.xml")
root = tree.getroot()
for order in root.iter('{http://publicapi.ekmpowershop.com/}Order'):
out = {}
for child in order:
if child.tag in ('OrderID'):
out[child.tag] = child.text
print(out)

You need to consider the namespace when checking for tags.
>>> # Include the namespace part of the tag in the tag values that we check.
>>> tags = ('{http://publicapi.ekmpowershop.com/}OrderID', '{http://publicapi.ekmpowershop.com/}OrderNumber')
>>> for order in root.iter('{http://publicapi.ekmpowershop.com/}Order'):
... out = {}
... for child in order:
... if child.tag in tags:
... out[child.tag] = child.text
... print(out)
...
{'{http://publicapi.ekmpowershop.com/}OrderID': '100', '{http://publicapi.ekmpowershop.com/}OrderNumber': '102/040718/67'}
If you don't want the namespace prefixes in the output, you can strip them by only including that part of the tag after the }
character.
>>> for order in root.iter('{http://publicapi.ekmpowershop.com/}Order'):
... out = {}
... for child in order:
... if child.tag in tags:
... out[child.tag[child.tag.index('}')+1:]] = child.text
... print(out)
...
{'OrderID': '100', 'OrderNumber': '102/040718/67'}
