You don't need the | (or) symbol in a character set. You can just use [vV]alue because it only matches one character in the [ ].

[DarkKnghtZ]

Thank you very much. I was looking for such a great example and excellent explanation on how to use this.

[secondline]

Thanks sir, i've solved my problem

[shaunhunterit]

I am following your channel..all ur videos much helpful for me to learn uipath and much useful.. thanks a lot..

[lakromani]

Correction:. You can use (v|V) or [vV]. This [v|V] means v or | or V.

[dr.mohammedmohammed]

This really helpful, i really enjoy how you teach, you are not just following the step like a guide tutorial, You also clarify each element and each step why we following it, I would like to ask something, If am using the Look behind expression, and i wont to get the number after it but not everything after how this expression (/(?<= The [v|V]alue is).*/gm) will look like ?

[Yeshvanthkannan]

Your video are awesome and helpful. Please create more play list for more benefits

[tagifts]

Thanks. How do you use it though? Search? Findall? Which method is best?

[itsmechethan]

we can give directly /Rs6545/gm what is the use in that (?<= the value is).\w(2)\d(0, ) can you please tell

[surajkamath]

When we run the same in Uipath it shows empty output.
Reading the text file.
Using Matches activity writing the regex exp
Using for each loop to display

[spurthishetty]

Hi How do we extract something like this ex Name : dummyname
here when i use your approach colon also comes.. i just want dummyname as the ouput how to get rid of colon as well, and colon will be present sometimes and absent sometimes so it should be optional like [:]?

[raulalvarezespinoza]

Could you explain how to use JavaCC, please?
It's very difficult to use.

[kavinnatarajan]

Hi how do I read something which ends with question mark

For example what is your hobby? Playing soccer. XXX
Here I’m trying to fetch soccer, starting text is what is your hobby ? And ending text is XXX. Im not getting expected output as it returns soccer with question mark in front.

Could you give expression for this

[dockeryz]

Why didn't you just use the case insensitive modifier?

[sivasankar]

Hai rakesh, I have one doubt
