The following examples demonstrate how to divide a dataset using the Regular Expression option. This example puts into the first dataset all rows that contain the text Gryphon in the column Textand puts other rows into the second output of Split Data :.
This example looks for the specified string in any position within the second column of the dataset, denoted here by the index value of 1. The match is case-sensitive. The first result dataset contains all rows where the index column begins with one of these characters: abcdef.
