Is there any tool or VI for labview that lets me search a string for expressions that are similar to a specified input string (i.e. deviate from the desired string by one or two characters)? I am using a camera and some software to read text from products as they pass down a conveyor belt, and the result is returned to labview as a string. Although the text is read correctly most of the time, it sometimes misinterprets a character or two, and this prevents me from using labview's 'rigid' string functions like 'Search and Replace' and 'Scan From String'. Surely someone has created more flexible options which can help me more easily identify products on the conveyor.
Thanks!
