Re: Need Function or UDF that does this...
These suggestions are all good. The problem I have is that I am searching out text from an cfhttp call. When I reverse the cfhttp.filecontent it becomes a huge mess and is difficult to work with.
Thanks for the ideas...

Re: Need Function or UDF that does this...
How about passing the string to reverse() first. Won't be perfect,
because you'll need to reverse your search string as well, and then
subtract the returned index from the length, and unreverse everything
to use it, but it'll function. YOu can wrap all that up in a UDF
pretty easily.
Or, if you're on CFMX and feeling adventurous, you can use the
lastIndexOf() method of the String class like this:
str = "this is a test string";
i = str.lastIndexOf("is") + 1;
I'm finding the last index of the string "is". Make sure you add one
to the result though, because Java is zero-indexed while CF is
one-indexed.
cheers,

The key part would be something like: find(substring, reverse(myString)) reverse() is built in to CF, so nothing special needed. Regards, Dave.

Re: Need Function or UDF that does this...
Still use Find() or FindNoCase()...but reverse the string using Reverse()...like so FindNoCase(Reverse(MyString)) HTH Cheers Bryan Stevenson B.Comm.

I need a function or udf that is like find() or findNoCase() except that it searches backward from a starting point instead of forward. In other words, it finds the first occurance of a substring within a string but searches backwards from a starting point.
