How to get offset of regex match?

[Suppir]

I have a string:

$string = "Bla bla bla"

And some code:

$Result = StingRegExp($string, "a", 1)

Now $Result contains 3 "a". But I need offsets of these matches from the beginning of the string (2, 6, 10). Is it possible to get offsets of matches in AutoIt?

Suppir,

Use StringInStr within a loop - something like this:

#include <Array.au3>

Global $aArray[4] = [1]

$sString = "Bla bla bla"

For $i = 1 To 3
    $aArray[$i] = StringInStr($sString, "a", 0, 1, $aArray[0])
    $aArray[0] = $aArray[$i] + 1
Next

_ArrayDisplay($aArray)

Melba23, while StringInStr does not support regular expressions, this way will not work if we have more complicated pattern. For example:

pattern = "[aо]$" (find "a" or "o" at the and of line)

StringInStr will not work.

Actually, I have to solve this problem to make possible one thing. I want to find some text in Edit (maybe RichEdit) with regular expressions, and then to highlight all matches. To do highlight of symbols I need to know their offsets from the start on string.

You know how hyperlink (www...ets) may be automatically highlighted in RichEdit. So, this is possible to other text.

Suppir,

If you ask the right question, you might get the right answer and save a lot of time.

Take a look at this:

#include <Array.au3>

Global $aArray[4]

$sString = "Bla bla bla"

$iOffset = 1

For $i = 1 To 3
    $aTemp = StringRegExp($sString, "a", 1, $iOffset)
    $iOffset = @extended

    $aArray[$i] = $iOffset - 1

Next

_ArrayDisplay($aArray)

Are we getting nearer?

"If you ask the right question, you might get the right answer and save a lot of time" - sorry fo my English

As for your script - it really works! Thanks

Actually I see "@extended" macros for the first time *digged in manuals*
