thanks.

If that's the exact format for all the strings then this will do it.

#include<array.au3> ;; For _ArrayDisplay() only
$sStr = "wqer zxcv(dfg xcv (sdf))"
$aRegEx = StringRegExp($sStr, "(?i).*?\h+([\w]+)", 3)
If NOT @Error Then
    _ArrayDisplay($aRegEx)
Else
    MsgBox(0, "", "Oooops")
EndIf

Thanks and sorry. It's will not work if string changes. I mean:

extract every first word, that is before "("

Is this what you mean?

$aRegEx = StringRegExp($sStr, "(?i).*?\h+([\w]+)(?:\(|\h)", 3)

If not then try to give us a couple examples of exactly what $sStr would contain and what you need returned.

Would that fit your bill?

#include <Array.au3>

Local $s = "wqer() zxcv(dfg xcv (sdf)) Return (seterror( 1, 0,Abs   (Sqrt(5))))"

$a = StringRegExp($s, '(?i)(?:(?:\A|[^a-z])(\w+)(?=\s*\())+', 3)
_ArrayDisplay($a)

In fact, it turned out a little bit more complicated than I first thought, but it seems to work as intended.

You might have to adjust your own definition of "word" and "space", but I'm sure you get the idea.

You're welcome with or without your God!

You see that I've taken steps to grab a "function name" at the beginning of string, or separated or not by whitespace(s) from the previous part. I'm sure you know enough to fine tune it to the definition your context imposes. The idea was to use forward assertion to match the "\s*\(" rather than simple matching, since the latter does "consume" matched chars that could possibly be triggering the beginning of a new "function name".

What do you want to take from it?

$sStr = "sldkfj sdf4g 555 dfg"
$aRtn = StringRegExp($sStr, "\b\w+\b", 3)

Will return an array where

$aRtn[0] = sldkfj

$aRtn[1] = sdf4g

$aRtn[2] = 555

$aRtn[3] = dfg

Edit: Removed case insensitivity since it's not required with this particular SRE

Like that?

#include <Array.au3>
Local $s = "wqer() 456() zxcv(dfg 123 xcv (sdf)) Return (seterror( 1, 0,Abs (Sqrt(5))))"
$a = StringRegExp($s, '(?i)\b([a-z][a-z0-9]+)\b', 3)
_ArrayDisplay($a)

_ArrayDisplay($a)

yes, thanks Edited by Godless

Little problem:

'(?i)\b([a-z][a-z0-9]+)\b'

not includes "_"

As you appear to be willing to capture AutoIt-style variables names, I've been surprised that the following works:

Local $_ = 5
Local $_8 = 5
Local $_a = 5
Local $8 = 3
Local $8_ = 3
Local $8a = 3
ConsoleWrite($_ & $_8 & $_a & $8 & $8_ & $8a & @LF)

In short a dollar sign followed by at least one of upper or lowercase ASCII letter, or decimal digit or underscore.

That's precisely the set that \w is accepting, so your regexp is simpler. If you combine variables and functions, you get this:

#include <Array.au3>
Local $s = "wqer( $_ ) 456() zxcv(dfg 123 $xcv ($sdf)) Return (seterror( $_1, 0,Abs (Sqrt($5))))"
Local $vars = StringRegExp($s, '(?i)(?<=[^[:word:]]|\A)(\$\w+)', 3)
_ArrayDisplay($vars)
Local $fcts = StringRegExp($s, '(?i)(?<=[^[:word:]$]|\A)([a-z_]\w+)', 3)
_ArrayDisplay($fcts)

Try it and let us know when it breaks!
