I found this example in the autoit help

;Option 1, using offset
$nOffset = 1
While 1
    $array = StringRegExp('<test>a</test> <test>b</test> <test>c</Test>', '<(?i)test>(.*?)</(?i)test>', 1, $nOffset)
    
    If @error = 0 Then
        $nOffset = @extended
    Else
        ExitLoop
    EndIf
    for $i = 0 to UBound($array) - 1
        msgbox(0, "RegExp Test with Option 1 - " & $i, $array[$i])
    Next
WEnd

but I didnt get what means (.*?)... any1 help?

. - Match any single character (except newline).

* - Repeat the previous character, set or group 0 or more times. Equivalent to {0,}

? - The previous character, set or group may or may not appear. Equivalent to {0, 1}

StringRegExp('<test>a</test> <test>b</test> <test>c</Test>', '<(?i)test>(.*?)</(?i)test>', 1, $nOffset)

The pattern looks for what ever is between <test> and </test>

(.*?) basically means it's going to stop at the next character in the sequence. Remove the '?' and all of the sudden your result is:

a</test> <test>b</test> <test>c

So it's going to grab ANY character '.'

It's going to repeat it '*' UNTIL '<'

Help clarify it for you?
