If you were using Perl, you could use this instead: [grep search=0+([0-9]+?)0+&replace=\1][likenumber][/grep]which would be the nongreedy version of 1 or more. In this case, you will have to pick off the initial zeros then strip the trailing zeros. Do this to strip the trailing zeros: [grep search=([1-9]+)0+$&replace=\1][likenumber][/grep]which is to say find any sequence numbers that do not include 0 and are followed to the end of line by only zeros and replace it by just the number.John -- John Peacock Director of Information Research and Technology Rowman & Littlefield Publishing Group 4720 Boston Way Lanham, MD 20706 301-459-3366 x.5010 fax 301-429-5747------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list
