Select color range? *pics*

Adobe photoshop CS2 has a great feature: select color range

how can i duplicate this effect in flash??

the reason being: i have complex black and white line drawings. when i import the vectored image (from illustrator) i then need to delete all the white space between the lines (to make them seem transparent), but instead of selecting all the white spaces and deleting them individually, i would like to simply select them all in one action and delete them all. (example below)
