[Solved] How to identify, if a string contains numbers?

Recommended Posts


Say there are billion strings like:

$string1 = 'AD 123456 d 265 SFreg'

$string2= '3255'

$string3 = 'AAA 87654321 reggw 234 sr EE#!¤ '


I wold like to filter out numbers from the strings. But the sequence must contain at least 5 numbers in a row. Is it possible to do so?

From this example only $string1 and $string3 are good & output should be




Is there a way to identify numbers in the string ?

Welcome the wonderful world of Regular Expressions! :D

This works for me - I get the results you required:

#include <Array.au3>

Local $aLines[3] = ['AD 123456 d 265 SFreg', '3255', 'AAA 87654321 reggw 234 sr EE#!¤ ']

For $i = 0 To 2

    $aRet = StringRegExp($aLines[$i], "\s(\d{5})", 3)

    _ArrayDisplay($aRet, "Line " & $i)


How about you? :)

I was reading about RE & was even able to filter out strings that contain numbers, but how to filter them out, this was something I could not figure out.

so basically its the same as this, thank you. problem solved.

$aRet = StringRegExp($aLines[$i], "([0-9]{8})", 3)
