regular Expressions in TestComplete

Good afternoon am Alejandro Canosa I have a number of concerns with regular expressions in TestComplete, I use the following method to evaluate aqString.StrMatches regular expressions (regexp, Zip) and regexp I assign the expression [0-9] {3,5} to allow numbers with 3-5 digits but when the Zip field is given a number that satisfies the condition I return false as if the value did not meet the condition, the problem is the method I use or regular expressions in TestComplete vary with the standard web? I would appreciate someone much more knowledgeable than I to explain to me or enlighten me because it's something I do not quite ented, thank you very much in advance

Hi,

Could you please post a sample of the code that is failing and an example of the data that is failing. It would be most helpful at investigating the issue.

Hey Alejandro,

I seem to come to the same conclusion (aqString.StrMatches returning false) as you. Bizzare, seems more complex expressions confuses the function :).

You can perhaps use a workaround for this (see below)?

Something like:

//JavaScript

var str = "15121";

var isNumber;

//This will search for digits [0-9] from the begining of the string (^) till the end ($)

//that has length 3,4,5 {3,5}

var pattern = "^[0-9]{3,5}$";

var regexpattern = new RegExp(pattern);

//exec returns null for no match, otherwise the string

var res = regexpattern.exec(str);

//inspect

isNumber = (res != null ? true : false);

//return

return isNumber

Regards,

Hi all,

The aqString.StrMatches method doesn't support the repeat count in {}. It uses {} to designate match groups. You can read more about aqString's regex syntax here.

If you need regular expressions with repeat count, use JScript's native regex engine as in Altus's example.
