Editing XML with ElementTree is also easy. To make things a little more interesting though, we’ll add another appointment block to the XML:

XML

<?xml version="1.0" ?>
<zAppointments reminder="15">
    <appointment>
        <begin>1181251680</begin>        
        <uid>040000008200E000</uid>
        <alarmTime>1181572063</alarmTime>
        <state></state>
        <location></location>
        <duration>1800</duration>
        <subject>Bring pizza home</subject>
    </appointment>
        <appointment>
        <begin>1181253977</begin>        
        <uid>sdlkjlkadhdakhdfd</uid>
        <alarmTime>1181588888</alarmTime>
        <state>TX</state>
        <location>Dallas</location>
        <duration>1800</duration>
        <subject>Bring pizza home</subject>
    </appointment>
</zAppointments>
