I’ve made this really simple XML. I like it the way it is… but it wont work ;(
Can somebody please see if Im even close. Would really help alot!!

Here’s the XML code - or take the TXT file and rename it to .xml

<?xml version="1.0" encoding="iso-8859-1"?>
<scamed>
<!-- MONDAY -->
    <mondayDate>21</mondayDate>
    <monN1>KORNÈL</monN1>
    <monN2>MAKODE</monN2>
    <monN3></monN3>
