Why is this bash IF statement not working?

if [[ $DATA == *?xml* ]]
then
    if [[ $DATA == *misuse* ]]
    then echo "Misuse" >> $OUTPUTPAST2
    else echo "All Good" >> $OUTPUTPAST2
    fi
else echo "Not xml" >> $OUTPUTPAST2
fi

Where $DATA does not contain the string ?xmlI am expecting an output of Not xml, but I am getting output of All Good.

What am I doing wrong?
