Answer 1

If you're trying to delete the audio_selector based on position, try:

xmlstarlet ed -L -d '//job/input/audio_selector[position() >= 2 and 20 >= position()]' profile.xml

If you're trying to delete the audio_selector based on value, try:

xmlstarlet ed -L -d '//job/input/audio_selector[number() >= 2 and 20 >= number()]' profile.xml
