Regex exactly 15 digits

[ATR]

Hi,

I have a problem (simply for you, but not for me !).

My string is "0821210101083128490000040001041437408000805301531233"

My pattern is d{10} and the result is true with the 10 first digits. I want a false answer !! because there is more than 10 digits !! I don't write d{10,) or d{10,)+ !!

What is the good regex ? ! ? !

Thanks

ATR,

 

I want a false answer !! because there is more than 10 digits

Why use a RegEx?

#include <MsgBoxConstants.au3>

$sString = "0821210101083128490000040001041437408000805301531233"

If StringLen($sString) > 10 Then
    MsgBox($MB_SYSTEMMODAL, "Error", "More than 10 digits!")
EndIf

A RegEx way :

If StringRegExp($sString, "^\d{10}$") Then MsgBox(0, "", "OK")

You can use StringLen($string)  to get the length of the string.

See post #2.

See post #2.

either one works...though #2 uses Regex

Post #2 is Mebla's, they are using StringLen().

My contribution. This also checks if the string is containing digits from 0-9.

#include <MsgBoxConstants.au3>

Local $sString = "0821210101083128490000040001041437408000805301531233"

If StringLen($sString) > 10 Or Not StringIsDigit($sString) Then
    MsgBox($MB_SYSTEMMODAL, "Error", "More than 10 digits or not containing digits!")
EndIf

jguinch's solution has the merit of
1/ answering the real initial question which seemingly was "What is the good regex ?"
2/ showing to ATR that he was near the correct regex as he already had the d{10} part

Not really, as knowing when to use a regular expression is just as important of what is the correct regular expression to use.

Does this mean that in this case a regex was not an appropriate answer ?

OTOH, we may assume that someone who tries to deal with regex already knows the use of StringLen - and just wants to learn something more

I never said that, both have "merit" in my opinion.

I never persume. If someone is coming from another language where they used regular expressions, then chances are they're not familiar with the language as of yet.

So much posts for a so little issue...

The question was about Regexp, so I just answered with a Regexp solution.
Now, Melba, DarthCookieMonster and Guinness answered with a different way, which is the simplest way, the way of learning, the obvious way to progress with a script language.
For these reasons, I think it's a good idea to provide these different solutions, for the asker's interest.
A lot of us like to use Regexp, but it's a good thing to sometime make a "booster shot".

Thank you to all for yours response,
