String Manipulation - RemoveChars

KNIME Analytics Platform
1

I am using the following expression to remove some stuff I do not need in column Serial_number

I want to remove (R) (L) (X) RIGHT LEFT

(removeChars(removeChars(removeChars(removeChars(($serial_number$, "(R)"),"(L)"),"(X)"),"RIGHT"),"LEFT"), " LEFT")

Although, I see it actually removes all Rs or Ls or Xs. etc.

How can I make it work? is there something like in dollar in excel "$(R)$"... just guessing..

Hi,

I didn't try it, but I guess that escaping the brackets with backslash characters would work - like this: \(R\)

Brackets and a few other characters have special functions in regular expressions and/or Java, and therefore need to be escaped when they are to be interpreted litereally.

HTH.

You should use replace with "" as its third parameter. So your expression should be something like:

replace(replace(replace(replace(replace($serial_number$, "(R)", ""),"(L)", ""),"(X)", ""),"RIGHT", ""),"LEFT", "")

Yes it did work! thank you!

If you have serial numbers (see examples bellow)

(1) 13A34R568Q

(2) 13B67F871R

and you want to delete only the R that is always at the end of the serial number (example 2), but definitely not the R that is in the middle of the serial number (example 1). How you can do that properly in string manipulation?

If you are familiar with Regexes, it is quite easy. I think there is a regexReplace function/manipulator in the String Manipulation node.

And if you're unfamiliar with Regex: specific Java Regex questions are usually answered within minutes on StackOverflow... :-)
