Extract exact number

hello @abbaszavar - it is good to have you here.  I would use Generate Attributes (best operator in RapidMiner IMHO) and do something like this if your column is labeled att1:

bloodPressure                 parse(suffix(att1, length(att1) - index(att1,"=") - 2))

Hi Scott,

Thanks for your reply.

It is just works if my variable was in the end of the line. Actually sometimes I have the same variable and its amount in the beginning or middle the line.

Could you please let me know how I can modify algorithm to can cover all possibilities?

Thanks in advance,

Abbas

hello @abbaszavar - in that case you should probably use a RegEx expression and slice+dice from there.
