Question

I am trying to write a regular expression that matches all occurrences of a specified word, but must not have any alphanumeric characters prefixed or suffixed.

For example, searching for the term “cat” should not return terms like “catalyst”.

Here is what I have so far:

"?<!([a-Z0-9])*?TERMPLACEHOLDER?!([a-Z0-9])*?"

This should return the word “TERMPLACEHOLDER” on its own.

Any ideas?

Thanks.

How about:

\bTERMPLACEHOLDER\b
