How to Create XML with ElementTree

Explore how to create XML documents with Python's ElementTree. Understand how to build XML structures programmatically, add elements and subelements, set values, and save them to files for data processing or storage.

We'll cover the following...

Python 3.5

import xml.etree.ElementTree as xml
def createXML(filename):
    """
    Create an example XML file
    """
    root = xml.Element("zAppointments")
    appt = xml.Element("appointment")
    root.append(appt)
    # add appointment children
    begin = xml.SubElement(appt, "begin")
    begin.text = "1181251680"
    uid = xml.SubElement(appt, "uid")
    uid.text = "040000008200E000"
    alarmTime = xml.SubElement(appt, "alarmTime")
    alarmTime.text = "1181572063"
    state = xml.SubElement(appt, "state")
    location = xml.SubElement(appt, "location")
    duration = xml.SubElement(appt, "duration")
    duration.text = "1800"
    subject = xml.SubElement(appt, "subject")
    tree = xml.ElementTree(root)
    with open(filename, "w") as fh:
        tree.write(fh)
if __name__ == "__main__":
    createXML("appt.xml")
