How to implement guide with xml namespace handling in python elementtree - typeerror on iteration
I'm running into a question while trying to parse an XML file that uses multiple namespaces with Python's ElementTree library. The structure of my XML looks like this: ```xml <root xmlns:ns1="http://example.com/ns1" xmlns:ns2="http://example.com/ns2"> <ns1:item>Item 1</ns1:item> <ns2:item>Item 2</ns2:item> </root> ``` When I attempt to iterate over the items, I use the following code: ```python import xml.etree.ElementTree as ET tree = ET.parse('myfile.xml') root = tree.getroot() for item in root: print(item.tag, item.text) ``` However, I'm working with a `TypeError: 'NoneType' object is not iterable`. This behavior suggests that the iteration is failing due to the namespace handling. I've tried specifying the namespaces directly in the iteration like this: ```python namespaces = {'ns1': 'http://example.com/ns1', 'ns2': 'http://example.com/ns2'} for item in root.findall('.//ns1:item', namespaces): print(item.tag, item.text) ``` But this only retrieves `ns1:item` elements. I need to access both `ns1:item` and `ns2:item`. What is the correct way to handle multiple namespaces in ElementTree to iterate through all items without running into type errors? Is there a more efficient method to fetch all child elements regardless of their namespace? I am using Python 3.8 and ElementTree from the standard library. I'm working on a CLI tool that needs to handle this. Any ideas what could be causing this?
