Python Library xml.etree.ElementTree

We parse the XML by ET.parse() method from file or ET.fromstring() method from string.

import xml.etree.ElementTree as ET
tree = ET.parse('xml.xml')
root = tree.getroot()

root = ET.fromstring("""<langs>
    <c rank="1"></c>
    <python rank="2"></python>
    <go rank="10"></go>
</langs>""")

Note that the returned value of ET.parse() is the ElementTree object <class 'xml.etree.ElementTree.ElementTree'>, while ET.fromstring() returns the root element with type <class 'xml.etree.ElementTree.Element'>.

The tag label and atttibutes of XML tag can be accessed by the tag and attrib property.

for loop is supported to iterate the children of element:

for lang in root:
    print(lang.tag, lang.attrib)
"""
c {'rank': '1'}
python {'rank': '2'}
go {'rank': '10'}
"""
