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'
text = elem.text
print(elem.tag + ' => ' + text)

if __name__ == '__main__':

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

<?xml version="1.0" ?>
<zAppointments reminder-"15">
<subject>Bring pizza home</subject>
<subject>Check MS office webstie for updates</subject>

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

Thanks for help!!

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/
