I wrote a small script that converts an m3u playlist to a k3b project.

Just save the following code snippet in a file called m3utok3b.sh, make it executable (chmod +x m3utok3b.sh) and run it (./m3utok3b.sh yourplaylist.m3u). Use it at your own risk!

echo application/x-k3b > mimetype

awk 'BEGIN{
  print "<?xml version="1.0" encoding="UTF-8"?>"
  print "<!DOCTYPE k3b_data_project>"
  print "<k3b_data_project>"
  print "<general></general>"
  print "<options></options>"
  print "<header></header>"
  print "<files>"
}
{
  if(index($0, "#") == 0) {
    gsub(/&/, "&amp;")
    print "<file><url>" $0 "</url></file>"
  }
}

END {
  print "</files>"
  print "</k3b_data_project>"
}' "$1" > maindata.xml

zip "$1.k3b" mimetype maindata.xml

rm maindata.xml
rm mimetype
