Import Old iTunes Library - Convert Old iTunes Library

After a recuperation of a TimeMachine of 2019 the iTunes Library inside was too OLD to be imported in the recent version MUSIC iTunes of Apple.

inside the iTunes folder there is a XML file "iTunes Music Library 2010-06-28 20.52.30.xml"

2 Problems need to be solved:

The Location of the files (New HardDrive)

in my case I had multiple different PATH need to be changed.

OLD_PATH1="file://localhost/Users/printi/Music/iTunes/"

OLD_PATH2="file://localhost/Volumes/Work/iTunes/"

NEW_PATH="file://localhost/Volumes/Matrice%20Raid/iTunes/"

To do the replacement of the path, create a file 'replace.sh'

in the Terminal:

1. vi replace1.sh
2. i (to insert)
3. paste the content
4. :wq (to save)
5. chmod +x replace1.sh (to give authorisations to be launched)
6. ./replace1.sh (to launch the script)

#!/bin/bash

# Chemin d'origine à remplacer
OLD_PATH1="file://localhost/Users/printi/Music/iTunes/"
OLD_PATH2="file://localhost/Volumes/Work/iTunes/"

# Nouveau chemin de remplacement
NEW_PATH="file://localhost/Volumes/Matrice%20Raid/iTunes/"

# Nom du fichier XML
XML_FILE="iTunes Music Library 2010-06-28 20.52.30.xml"

# Vérifie si le fichier XML est lisible
if [ -r "$XML_FILE" ]; then
    # Effectue le remplacement de tous les chemins dans le fichier XML
    sed -i '' "s@$OLD_PATH1@$NEW_PATH@g" "$XML_FILE"
    sed -i '' "s@$OLD_PATH2@$NEW_PATH@g" "$XML_FILE"

    echo "Tous les remplacements de chemin ont été effectués avec succès dans le fichier $XML_FILE."
else
    echo "Le fichier $XML_FILE n'est pas lisible."
fi

The sorting of iTunes that have changed from

file://localhost/Volumes/Work/iTunes/iTunes%20Music/Artist/Album/filename.mp3

to

file://localhost/Volumes/Work/iTunes/iTunes%20Music/Artist/S/filename.mp3

The Goal is to reuse the Album name and replace the S into the file url

<key>Artist</key><string>Bonnie Tyler</string>

<key>Album</key><string>Slowtime 02</string>

<key>Location</key><string>file://localhost/Volumes/Work/iTunes/iTunes%20Music/Bonnie%20Tyler/S/01%20Total%20Eclipse%20Of%20The%20Heart.mp3</string>

Result:

<key>Location</key><string>file://localhost/Volumes/Matrice%20Raid/iTunes/iTunes%20Music/Bonnie%20Tyler/Slowtime%2002/01%20Total%20Eclipse%20Of%20The%20Heart.mp3</string>

in the Terminal:

vi replace2.sh

i (to insert)

paste the content

:wq (to save)

chmod +x replace2.sh (to give authorisations to be launched)

./replace2.sh (to launch the script)

#!/bin/bash

# Define XML file name
XML_FILE="iTunes Music Library 2010-06-28 20.52.30.xml"

# Check if the XML file is readable
if [ -r "$XML_FILE" ]; then
    # Temporary file to store updated XML
    TEMP_FILE="temp.xml"
    # Variable to hold the current album name
    CURRENT_ALBUM=""

    # Read the XML file line by line
    while IFS= read -r line; do
        # Check for album name and update the CURRENT_ALBUM variable
        if [[ $line =~ \<key\>Album\</key\>\<string\>(.*)\</string\> ]]; then
            CURRENT_ALBUM="${BASH_REMATCH[1]}"
        fi

        # Check if the line contains the location key and path with "/S/"
        if [[ $line == *"<key>Location</key>"* && $line == *"/S/"* ]]; then
            # Prepare the album name for URL by replacing spaces with %20
            ALBUM_FOR_URL="${CURRENT_ALBUM// /%20}"
            # Replace "/S/" with the URL-safe album name in the path
            NEW_LOCATION=$(echo "$line" | sed -E "s@/S/@/${ALBUM_FOR_URL//@/%40}/@")
            echo "$NEW_LOCATION" >> "$TEMP_FILE"
        else
            echo "$line" >> "$TEMP_FILE"
        fi
    done < "$XML_FILE"

    # Replace the original XML file with the updated one
    mv "$TEMP_FILE" "$XML_FILE"
    echo "Updates have been successfully applied to the file $XML_FILE."
else
    echo "The file $XML_FILE is not readable."
fi

Hope this will help.
