content search in dbm file


Would be great if i get an answer in how to perform a content search in webMethods.

Say i have a file named logging.dbm

Basically i need to search for a line which has a *.ora in logging.dbm file, if this line exists, then print this line or else print that the line with .ora didnt exist.

I want to know how can i perform this activity in webMethods.

Appreciate your reply.
