implementing Parsing Complex XML in Python - Managing Namespaces and Attributes
I'm stuck trying to I've encountered a strange issue with I'm currently dealing with XML files that contain multiple namespaces and attributes, which makes parsing a bit challenging. The XML looks something like this: ```xml <root xmlns:ns1="http://example.com/ns1" xmlns:ns2="http://example.com/ns2"> <ns1:item id="1"> <ns2:name>Item One</ns2:name> <ns2:description>First item description</ns2:description> </ns1:item> <ns1:item id="2"> <ns2:name>Item Two</ns2:name> <ns2:description>Second item description</ns2:description> </ns1:item> </root> ``` I’m using Python 3.8 with the `xml.etree.ElementTree` module for parsing. My goal is to extract the `id`, `name`, and `description` of each item, but I'm getting exploring with the namespaces. Here’s what I’ve tried: ```python import xml.etree.ElementTree as ET xml_data = '''<root xmlns:ns1="http://example.com/ns1" xmlns:ns2="http://example.com/ns2"> <ns1:item id="1"> <ns2:name>Item One</ns2:name> <ns2:description>First item description</ns2:description> </ns1:item> <ns1:item id="2"> <ns2:name>Item Two</ns2:name> <ns2:description>Second item description</ns2:description> </ns1:item> </root>''' root = ET.fromstring(xml_data) items = [] for item in root.findall('{http://example.com/ns1}item'): item_id = item.get('id') name = item.find('{http://example.com/ns2}name').text description = item.find('{http://example.com/ns2}description').text items.append({'id': item_id, 'name': name, 'description': description}) print(items) ``` When I run this code, I get a `KeyError` because it seems that `item.find('{http://example.com/ns2}name')` is returning `None`, which leads to trying to access `.text` on a `NoneType`. I suspect it's something to do with how the namespaces are being handled. I also tried using `register_namespace` but wasn't sure how to implement it properly. Any insights on how I can correctly parse this XML structure and avoid these errors? I appreciate any help! I'm working with Python in a Docker container on Windows 11. Any ideas what could be causing this? The stack includes Python and several other technologies.
