I am no expert, but

iwlist eth1 scan | grep -o 'ESSID\"[^\"]*\"' | while read f ; do echo "{f:6}" ; done

does something, maybe this could be fed into an array and accessed from it

read section "Parameter Expansion" in bash manual page, sure you will find better solution there

maybe awk could be better tool for this, but again, I am no expert...
