I have many rows in a database that contains XML and I’m trying to write a Python script to count instances of a particular node attribute.
My tree looks like:
<foo> <bar> <type foobar="1"/> <type foobar="2"/> </bar> </foo>
How can I access the attributes
"2" in the XML using Python?
ElementTree. There are other compatible implementations of the same API, such as
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
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)
And similar, usually pretty simple, code patterns.
