bash grep results into array

Question

In bash I'm trying to collect my grep results in array, each cell holding each line. I'm downloaing urls with this line

wget -O index -E $CurrentURL

and then i want to grep the 'index' file results (other urls) into array each line per cell, what should be the correct syntax?

Array=(grep "some expression" index)

??

Answer 1

 readarray GREPPED < <(grep "some expression" index)
 for item in "${GREPPED[@]}"
 do
     # echo
     echo "${item}"   
 done

Oh, and combine those -v greps like so:

 egrep -v '\.(jpg|gif|xml|zip|asp|php|pdf|rar|cgi|html?)'
