How can I remove characters from a string of text

syaczol

I'm new to RapidMiner and looking for a solution.  I need to remove all characters following ".html" within a string of text.  If I was using excel or some other programs, I would typically default to using a combination of 'left' and 'InStr' functions.  Any assistance is greatly appreciated.

You should be able to do it using regular expressions with the Replace operator.
