Condition to see if the string starts with three letters and the rest are numbers

[req7 (Felipe Leite)]

Hello everyone,

I have a .txt file from which I read a large text, filled with strings. However, I just want to get the strings that start with three letters and the rest are numbers (example: BTV1138903 or BCU507).
How could I make this kind of condition?

I’ve been trying to solve this problem for a few days and I still haven’t succeeded

Somebody help me please

Use regex activities, IsMatch and Matches
Specify input as your text from.txt file
Pattern as [A-Z]{3}[0-9]*

How specific text from email body outlook

Once you get the email body, use regular expression to extract the required values. In UiPath, there are two extensive regex methods that will help you achieve this, IsMatch and Matches. Below are the expressions you can use, Total: (?<=total[ :]+)[0-9.,]+ Average: (?<=average[ :]+)[0-9.,]+ References:

Use this regex where MyStr is your string:

MyStr = System.Text.RegularExpressions.Regex.Match(MyStr, "[A-z]{3}\d+").Value.
