Not matching

how to compare find not matching item and two data table and how to share workflow

Hey!

Try this

System.Text.RegularExpressions.Regex.isMatch(strVariable,Pattern)

The above expression will give you the true or false.

Provide this in If condition to check if matched value is available in the string or not

It could be better to provide the sample input and expected output
