i want to separate names from a column.  For example

smith john b & mary


should give me

smith john b

smith mary


i am able to split the name but not able to bring the "last name - smith over to second person"


so i am getting


smith john b

mary <-----  want to see "smith mary"


in excel i can use the "left" statement until it find space but not sure how to do this in rapidminer

    Thanks for your reply.  I have been testing the solution you provided but still facing some other issues.  I will let you know once I have it working.

    I agree with Lionel that the Spilt operator will allow you to separate all the names out into separate attributes and then you can combine them using subsequent rules of your choice.
