Not 100% sure this is what you're wanting, but you can just do  
something like:

grep "myregex" * | awk -F ':' '{print $1}'

This will print out the first column (ie, whatever comes before the  
first colon).

if the options are either "<BODY>" or "<BODY BGCOLOLR="#FFFFFF">"  I  
guess you  could do something like:

grep "<BODY" * | grep -v BGCOLOR | awk -F ':' '{print $1}'

to get the files that have a body line sans BGCOLOR (you might need  
to account for case in the tags also)
