I need a Regex that will look at the last word in the string and eliminate it if it's a word that I've selected. For instance, if I'm selecting the word "dog," "This dog is a great dog" would return "This dog is a great." I don't want it to affect all the instances of that word, only if it happens to be at the very end of a string.
This is for a Yahoo Pipe that I'm setting up. Thanks in advance for your help. -Mike
The regex \bdog$ matches only at the end of the string. If there can be whitespace after your keyword, try \bdog\s*$. If you want to allow other characters (except for alphanumerics) after dog, for example punctuation, then use \bdog\W*$.
\b is a word boundary anchor that makes sure that only an entire word dog is matched - not part of a word as in underdog.
\s matches whitespace.
\w matches an alphanumeric characters; \W matches anything that's not an alnum.
