Mac OSX Terminal – Get Artist and Song From iTunes PlayList Export

There are more elegant ways to do this but I got bored and thought I’d do something that is only done with base Mac OSX tools

#!/bin/sh

#  Read_iTunes_PlayList.sh
#
#  Get only the artist list - remove duplicates
#  Read_iTunes_PlayList.sh 1 iTunesPlayListFileName ~/Desktop
#
#  Get Artist and Song Name
#  Read_iTunes_PlayList.sh 2 iTunesPlayListFileName ~/Desktop

XMLOption=$1
XMLFileName=$2
XMLFilePath=$3

case $XMLOption in
1)
# Only Get the Artist

clear
#echo $XMLOption
#echo $XMLFileName
#echo $XMLFilePath

rm -rf $(echo $XMLFilePath/$XMLFileName).txt || :

#echo "Parsing XML"
music=`grep 'Artist' $(echo $XMLFilePath/$XMLFileName.xml) | \
sed 's/<key>Artist<\/key><string>//g'| sed 's/<\/string>//g' \
| sed 's/%20/ /g' | sort`;

old_IFS=$IFS

# IFS by default is space tab return, and stands for
# Internal Field Separator.
IFS='

for i in $music
do
`echo $i >> $(echo $XMLFilePath/$XMLFileName.txt)`;
done

IFS=$old_IFS

cat $(echo $XMLFilePath/$XMLFileName.txt) | sed -e 's/^[[:space:]]*//' -e 's/[[:space:]]*$//' > $(echo $XMLFilePath/$XMLFileName_01.txt)

sed -i -e "s|&#38;|\&|g" $(echo $XMLFilePath/$XMLFileName_01.txt)
sed -i -e "s|&#60;|\<|g" $(echo $XMLFilePath/$XMLFileName_01.txt)
sed -i -e "s|&#62;|\>|g" $(echo $XMLFilePath/$XMLFileName_01.txt)

sort $(echo $XMLFilePath/$XMLFileName_01.txt) | uniq | grep -v '<key>' > $(echo $XMLFilePath/$XMLFileName.txt)
