I am writing this bash script and i need to remove part of a string

Code:

#!/bin/bash

allTracks="/var/www/music/xml/tracks/all.xml"
touch "$allTracks"
echo "<allTracks>" >"$allTracks"

artistFilename="/var/www/music/xml/artists/all.xml"
touch "$artistFilename"
echo "<artists>" >"$artistFilename"
for level1 in *
do
        echo "<artist Artist=\"$level1\" XMLLink=\"xml/artists/$level1.xml\"></artist>" >>"$artistFilename"
        albumFilename="/var/www/music/xml/artists/$level1.xml"
        touch "$albumFilename"
        echo "<artist>" >"$albumFilename"
        for level2 in "$level1"/*
        do
                echo "<album albumTitle=\"$level2\" XMLLink=\"xml/albums/$level2.xml\"></album>" >>"$albumFilename"

                if [ -d "$level2" ]
                then
                        if [ ! -e "$level1" ]
                        then
                                mkdir "/var/www/music/xml/albums/$level1"
                        fi

################################################## HERE
                        echo "<album albumTitle=\"$level2\" XMLLink=\"xml/albums/$level2.xml\"></album>" >>"$albumFilename"
                        trackFilename="/var/www/music/xml/albums/$level2.xml"
                else
                        trackFilename="/var/www/music/xml/albums/$level1.xml"
                fi
                touch "$trackFilename"
                echo "<album>" >"$trackFilename"
                #parse each mp3 file for info and insert to xml file

                if [ -d "$level2" ]
                then
                        for title in "$level2"/*.mp3
                        do
                                mp3info "$title" -p "\n\t<track number=\"%n\" trackTitle=\"%t\" filename=\"mp3/%F\"></track>" >>"$trackFilename"
                                mp3info "$title" -p "\n\t<track number=\"%n\" trackTitle=\"%t\" filename=\"mp3/%F\"></track>" >>"$allTracks"
                        done
                else
                        for title in "$level1"/*.mp3
                        do
                                mp3info "$title" -p "\n\t<track number=\"%n\" trackTitle=\"%t\" filename=\"mp3/%F\"></track>" >>"$trackFilename"
                                mp3info "$title" -p "\n\t<track number=\"%n\" trackTitle=\"%t\" filename=\"mp3/%F\"></track>" >>"$allTracks"
                        done
                fi
                if [ -f "$level2" ]
                then
                        echo "<album albumTitle=\"$level2\" XMLLink=\"xml/albums/$level1.xml\">" >>"$albumFilename"
                fi

                echo "</album>" >>"$trackFilename"
        done
        echo "</artist>" >>"$albumFilename"
done

echo "</allTracks>" >>"$alltracks"
echo "</artists>" >>"$artistFilename"

I put a comment where the problem is.

$title2 outputs to '$title1/*' where * is anything in folder '$title1'

i need to strip out everything before the '/' in $title2. i tried using sed with the 'D' opperand but couldn't get it to work. any help is much appreicated.

thanks in advance,

I don't even see title1 or title2 in that script? Are you perhaps thinking about level1 and level2?

To strip the path part of a filename use basename command, e.g.
$ title2=/path/to/mymusic/title2.mp3;basename $title2
title2.mp3
