Parsing string

[Daydreamer067]

Hi

I want to parse a string to return all the words separated by space.

"string exemple" would return string and exemple.

I tried with StringRegExp but I don't know how to make it work.

Your help is appreciated.

Maybe something like this?

#include <Array.au3>
#include <StringConstants.au3>


Test()

Func Test()

    Local $arrResult

    $arrResult = StringRegExp("This is a test string with spaces." & @CRLF & _
                              "  Even with leading speaces,  double spaces, or trailing spaces    .",  _
                              '(\b\w+\b)', _
                              $STR_REGEXPARRAYGLOBALMATCH)

    _ArrayDisplay($arrResult)

EndFunc

It doesn't always have to be regex:
 

#include <Array.au3>

$sString = "string  exemple"

$aSplit = StringSplit(StringStripWS($sString, 7), " ", 2)
_ArrayDisplay($aSplit)

Not false. But you grab the final dot too, and there is an issue (for me) with the string provided by @FrancescoDiMuro

How does the final point relate to the thread creator's task?

Your code returns the final dot as a valid result
The question was about 'return all the words' so I doubt the OP could be interested in a dot 

[AspirinJunkie]

The only information about the source we have is: "words separeted by space".
Nothing read about a point or anything else.
Especially if no point at all appears in the example of the questioner. The point was first introduced by Francesco.
So up to here, there is no reason to cover points extra.

Therefore, it does not make much sense to extend the task further than it was set.
Otherwise, one could also say that Francesco's code also extracts words that are not separated by spaces but only by semicolons.
For the task given so far, however, his code fulfills the task completely correctly and is sufficient until Daydreamer specifies the task further.

I would like to agree with @AspirinJunkie regarding this issue. The general conditions that the questioner has mentioned are insufficient for a more precise answer. Crystal balls are quite rare in our times .

different strokes and all

i like both methods, and to tell the truth, my regexp fu is weak

In fact we have (spaces excepted) no information at all... 'parsing string' is very vague. Is this source string a text ? How should we parse "AutoIt v3 is a freeware BASIC-like scripting language." ? 
In such cases as usual we try to guess (maybe wrongly) what could be inside the subject 'string'

fair enough, however what we use to try and guess is strongly influenced by what is presented, in this case:

which, while admittedly offering little to go on, does not appear to be a sentence.
furthermore, at this point the OP doesn’t seem concerned with any subtle details:

and although he mentions specifically StringRegEx in his question,  the answer need not use such.

at this point though, I think the OP has been more than adequately served by all

[FrancescoDiMuro]

And this, ladies and gentlemen (I said gentlemen, so regex cats are not included), it's how a simple question become the official thread of "word or not word, this is the question" 

Spoiler

For the regex cat @mikell, just kidding.

I love every regex pattern you post

unless the OP returns, I’m thinking that we’ve been expertly trolled by someone who, (being aware of the community’s bitter divide  between those who RegEx and those who do not), has served up a perfectly ambiguous, right-down-the-middle-of-the-road question for us to squabble over, while he smugly sits back; chuckling as he mumbles “exemple”.
