How can I parse XML and get instances of a particular node attribute?

I have many rows in XML and I'm trying to get instances of a particular node attribute.








How do I access the values of the attribute foobar? In this example, I want "1" and "2".

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:
import 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:
for type_tag in root.findall('bar/type'):
value = type_tag.get('foobar')
print(value)


Output:

1
2
