How to manipulate a part of string: Split, Trim, Substring, Replace, Remove, Left, Right

Okay Patrick, I get it now. You only need to extract the ID numbers. :sweat_smile:

The solution is as follows:

splitedString = System.Text.RegularExpressions.Regex.Replace(inputString.Trim, "[^\p{N}]" , " ")

Change separator in “Split String” activity from "/" to " "

Then assign array to remove empty items:

splitedString = splitedString.Where(Function(x) Not String.IsNullOrWhiteSpace(x)).ToArray

Output data:

Hi Adrian,
Is working perfectly now and this is really cool and fun getting the robot to work…I learn something new each time I posted my problem and thank you so much for your time and guidance.


Great work, helps a lot. Thank you.

Hi Adrian,
Apologies to trouble you again, as I am trying to optimising the bots on some reducancy process and as of how could I remove those duplicate numbers in the array? I have try Union (from this link How to remove a duplicates values from the array and listbut couldn’t get the result.

Thanks you in advance for your help and guidance once again.

Hi @patrick-cm.kok
Have you checked this code from below?

Example data:

arr_numbers = {123456,123456,234567,345678,234567,456789,123456}
arr_strings = {"123456","123456","234567","345678","234567","456789","123456"}


arr_numbers = arr_numbers.Union(arr_numbers).ToArray
arr_strings = arr_strings.Union(arr_strings).ToArray



Hi Adrian,
Thanks you for your reply, I did try but couldn’t get the result as desired. Below are the screenshot for your reference.

Use :.Trim to replace white spaces from values. This seems to be the cause.

Thanks Adrian for your help, is there any proposal solution? I try to remove the duplicate first before the split but it don’t work as well.

Send the workflow and a file with sample data (they can be pseudo data)
I will take a look at what you have prepared and refer to it.

Hi good morning.

I am creating a bot that captures a text of type Int from the screen and this captured text always changes length, going up to 5 characters or more. I need regardless of the fetched text to save the text from the first digit to the penultimate.

Can you help me please, thank you.

Hi @Melanny_Herrera_Cruz ,

You can use a regular expression:

output = System.Text.RegularExpressions.Regex.Match(inputString,"\b\d+(?=\d)").Value

output = String
inputString = String

Output as shown on screen:

Example link to visualize:

Pattern explanation:
start with the word boundary ( \b ),
get numbers that are more than 1 ( \d+ ),
end on a one-digit pattern without taking a character ( (?=\d) ).
