Extracting numbers from string.

Recommended Posts


Hi all, can someone PLEASE answer this for me...it may be very simple but I cannot think at the moment. And all searches shows something different.

Lets say I have a string...$data = "0123abc". Now how do I extract the numbers from $data? Please note $data can vary (may have a prefix zero, letters, special characters, blank spaces and so on).

Your help will be greatly appreciated.

Try this:

$sData = "0123abc"

$sDigits = StringRegExpReplace($sData, "\D", "")

ConsoleWrite($sDigits & @CRLF)

From the RegEx page in the Help file:

\D -- Match any non-digit

So it should work in all the cases you mention.


Edit: Pressed wrong button too early!

$data = "0123abc43598zwewef  %&&$§$$§  we83223"
$result = ""
while StringLen ( $data ) > 0
    if StringIsDigit ( stringleft ($data, 1) ) = 1 then $result = $result & stringleft ($data, 1)
    $data = StringTrimleft ( $data, 1 )

maybe this helps you :D

Thank you all. StringRegExpReplace($data, "\D", "") worked pretty well.

Thank you.
