I think this example can help:
Code:
cat INPUTFILE
222
some text ["i want this string"] anything else ["and this one too"] end
1111
some text ["i want this string"] 
333

cat INPUTFILE | sed 's/\[/\n[/g; s/\]/]\n/g' | sed -n '/^\[\(.*\)\]$/ s//\1/p'
"i want this string"
"and this one too"
"i want this string"

PS It's "useful use of cat".
