Unknown error when using lxml module - parsing XML

am curently learning using Python 101 and in one of examples I'm getting an error and have no clue how to fix it - my code is 100% same as in the book (checked it 3 times already) and it still outputs this error.
Here is the code:

from lxml import etree

def parseXML(xmlFile):
"""
Parse the xml
"""
with open(xmlFile) as fobj:
xml = fobj.read()

root = etree.fromstring(xml)

for appt in root.getchildren():
for elem in appt.getchildren():
if not elem.text:
text = 'None'
else:
text = elem.text
print(elem.tag + ' => ' + text)

if __name__ == '__main__':
parseXML('example.xml')


and here is xml file (it's the same as in the book):

<?xml version="1.0" ?>
<zAppointments reminder-"15">
<appointment>
<begin>1181251600</begin>
<uid>0400000008200E000</uid>
<alarmTime>1181572063</alarmTime>
<state></state>
<location></location>
<duration>1800</duration>
<subject>Bring pizza home</subject>
</appointment>
<appointment>
<begin>1234567890</begin>
<duration>1800</duration>
<subject>Check MS office webstie for updates</subject>
<state>dismissed</state>
<location></location>
<uid>502fq14-12551ss-255sf2</uid>
</appointment>
</zAppointments>


EDITED: Sry, got so excited about my first post that I actually forgot to put the error code.

Thanks for help!!

Answer

The only error in the xml can be found here: <zAppointments reminder-"15">, should be: <zAppointments reminder="15">.

In the future useful tools for validating xml can be found online. Here for example: https://www.xmlvalidation.com/
