python - How can I parse XML and get instances of a particular node attribute? - Stack Overflow
What should I use for XML parsing in python3?
If you are just doing basic XML parsing, I would recommend using ElementTree. If you are using namespaces, I would recommend switching to lxml.
BeautifulSoup is also good.

How to parse XML in Python?
You can parse XML files in Python using tools such as ElementTree, lxml, or query languages like XPath. Be sure to handle potential issues like an xml parse error using proper error handling.
What is parsing in XML?
Parsing in XML means searching through the XML elements to get their data. This can be achieved by matching against elements' tags, attributes, or values.
What's the difference between XML and HTML?
HTML is an XML-based markup language used for creating web pages so it's a more restrictive version of XML. Fortunately, both markups are very similar and can often be parsed using the same tools.

I suggest ElementTree. There are other compatible implementations of the same API, such as lxml, and cElementTree in the Python standard library itself; but, in this context, what they chiefly add is even more speed -- the ease of programming part depends on the API, which ElementTree defines.
First build an Element instance root from the XML, e.g. with the XML function, or by parsing a file with something like:
Copyimport xml.etree.ElementTree as ET
root = ET.parse('thefile.xml').getroot()
Or any of the many other ways shown at ElementTree. Then do something like:
Copyfor type_tag in root.findall('bar/type'):
value = type_tag.get('foobar')
print(value)
Output:
1

minidom is the quickest and pretty straight forward.
XML:
Copy<data>
<items>
<item name="item1"></item>
<item name="item2"></item>
<item name="item3"></item>
<item name="item4"></item>
</items>
</data>
Python:
Copyfrom xml.dom import minidom
dom = minidom.parse('items.xml')
elements = dom.getElementsByTagName('item')
print(f"There are {len(elements)} items:")
for element in elements:
print(element.attributes['name'].value)
Output:
There are 4 items:
item1
item2
item3
item4
