Fellow Boosters, I am looking for a little guidance with the regex library. I have an application that I would like to use regex for. I am new to regex so I am not sure how to approach it. Mostly I am reading. The examples so far have been very impressive, but so complicated as to make it difficult to understand how to do something simple. What I would like to do is process a string (or file) that has many symbols that are delimited with something like "&foo;". The delimiters are not that interesting. Just something to make them easy to locate. The string between the delimiters is then used to lookup a replacement string and substituted. I would search for something like "&.*;". The examples show how a basic search and replace would work, but how would I do something with a looked-up replace? ...Duane -- "If tyranny and oppression come to this land, it will be in the guise of fighting a foreign enemy." - James Madison
