Regular expression not working

[neha.verma]

Any possible reason for validate not working in this case though element attribute ‘idx’ is just 3 digit number only.

Hi @neha.verma ,

You would also require to add another attribute :

matching:idx='regex'

Check the below post on how to use regex in Selectors :

#FeatureBlog - 19.10 - Using regular expression (Regex) in the selector attributes

It is now possible to use Regular Expressions in your selectors. Follow this guide to learn how! What’s new? We have added extra syntax to the Selector Editor to allow for advanced configuration of your selectors. Let’s begin As an example, I will be creating a selector that will be able to open a file whose name is dynamically changing. Let’s assume I am receiving daily list of bills via email which are saved as a text file named ‘bills mmddyy.txt’, e.g ‘’bills 101019’. Now, I want to writ…

Hello @neha.verma
You can provide ???
?- replaced 1 charector
hope this helps.
Sorry dont have idea regex works in selectors or not.

[neha.verma]

added matching:idx=‘???’ and still fails validation. Infact after adding matching tag, it fails with exact value as well indicating that matching keyword is not working here. Any suggestions?

@neha.verma ,

Could you provide us with the Selector that you are using ?

@neha.verma

matching:idx=‘???’ and still fails validation

I tried and it fails.

[Shubham_Kinge]

without providing matching provide idx=???
Hope this helps

@neha.verma

added matching:idx=‘???’

@neha.verma ,

In the Selector, you have to provide the regex expression in the idx attribute itself :

idx = '\d{3}'

You have to add another attribute to make the compiler understand that the idx is ahving a regex expression so the below is to be added next :

matching:idx='regex'

[neha.verma]

Great, it worked. Thanks much!

[neha.verma]

It is resolved now by using
matching:idx=‘regex’

[neha.verma]

@supermanPunch

matching:idx='regex'

Hi,

It is again not working today.

Can you please suggest any possible reason?

[supermanPunch (Arpan)]

@supermanPunch

idx = '\d{3}'

@neha.verma ,

The Regex Expression is wrong.

We mention Either \d+ or \d{3}.

+ would mean one or more match of the Preceding character.
{3} specifies exactly 3 digit match.

I tried idx=‘???’ as well and this was working last time as it is a 3 digit number.

I tried with \d+ as well, any more suggestions?

@neha.verma ,

We would need to understand what are the possible values the idx can have for your case or scenario.

Could you indicate the element and check what value it would have at different scenarios ?

[neha.verma]

Sure, this could be any 3 digit number like 134, 401 etc. It is a checkbox whose idx value could be any 3 digit number.

I also feel that the problem is not my regular expression but somehow, the regular expression is not working and it worked yesterday

It is a checkbox whose idx value could be any 3 digit number.

@neha.verma ,

Do confirm when it is failing what is the value of the element. So we can confirm if the regex works properly.

As you have mentioned 3 digits, The Regex Expression should be \d{3}. This would fail if the idx value is less than 3 digits or more than 3 digits.

[neha.verma]

@supermanPunch The idx value in my current case is 401 and the regular expresion ‘???’ or \d{3} is failing

@neha.verma ,

Could you use UiExplorer and indicate the Element again and check what is the difference between the Selector that you have used and the Current Indicated element’s selector ?

[neha.verma]

Ok, let me try. But when I click ‘Open in UI Explorer’, nothing happens. Do I need any package for this?

Edit: It opened now, thanks.

[neha.verma]

@supermanPunch Please help, I don’t see any difference in the locators that I am using and the ones displayed in UiExplorer

Why my regular expression could not be working?
