Ifyou 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, youwill have to pick off the initial zeros then strip the trailingzeros. 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 andare followed to the end of line by only zeros and replace it by justthe number.John -- John PeacockDirector of Information Research and TechnologyRowman & Littlefield Publishing Group4720 Boston WayLanham, MD 20706301-459-3366 x.5010fax 301-429-5747-------------------------------------------------------------This message is sent to you because you are subscribed to the mailing list
