stringregexp instead of stringsplit

[SmOke_N]

Using \|? in the regex will always return a match even if there's no pipe... if that's the goal, then (.*?)\|? is fine.

However, if you only want an array if there is a pipe in the string, then you'd be looking at something like (.*?)(?:\||\z) instead.

Edit:

Don't listen to my 42 hours of being up babble, mine will return the same thing as \|?!

it was just the difference between the results using Expresso and everything else :-

using "one|two|" and the exp (.*?)\| , 3

AutoIt returns :-

one

two

Regulazy returns :-

one

two

Expresso returns :-

one|

two|

its just an odd result with that particular program thats all, dont like it myself its a bit confusing i prefer Regulazy to help build expressions i think.

and i payed for expresso

cant figure out reulazy

You have to also remember that there are differences in RegEx engines. AutoIt uses the PCRE engine and many of the tools available don't recognize the PCRE syntax. Always check to see what engines it supports. Example: If it says that it's for DOT NET Regexp then the reults will not always be accurate with PCRE.

well it is fine as long as you remember its results have the end expression character(s) at the end of each result (for some reason)

i think i misunderstood what you was saying about the end "|" though, you was not talking about how all the results returned from Expresso have the "|" but that yuo want

one|two to return :-

one

two

without the last pipe! soz for misunderstanding , but what i said before still stands.

well i cant figure out what the exp should be but i know what your after, i dont know how to say "break at "|" or end of string" kinda thing.

well after what seems like an age what about this :-

$A_SRE=StringRegExp ($string,"(.*?)(?:\||\z)",3)

i think it works just about, does give 1 extra NULL array entry at the end.

EDIT:- GOT IT , WOOHOO (.+?)(?:\||\z)

GOOD WORK JackDinn.... i was sooooo close to finishing too..

This is using your code i had (\||\z) at the end which gave lots of NULL results

$string="one|two|three|four|five|six|seven|testx testy | mary had a little lamb"
$reg="(.*?)(?:\||\z)"

$split = StringRegExp($string,$reg,3)
_ArrayDelete($split,UBound($split)-1)
_ArrayDisplay($split)

np, if you didn't catch my EDIT i even found how not to get the extra NULL at the array end so

$A_SRE=StringRegExp ($string,"(.+?)(?:\||\z)",3) == StringSplit ($string,"|")

the delimiter is the "\|" but im sure your ok with it from here.

no prob, glad to learn along with ya.

[GEOSoft]

Is this what you were looking for Jack

"(?i)\|?\b(.+?)\b\|?"

Edit: bettter yet

"(?i)\|?\b([\w\s]+)\b\|?"

interesting results tho.

$string=""
$split=""
for $x=1 to 5000
$string&=Random(100,100000,1)&"|"
Next

$timer=TimerInit()
$split = StringRegExp($string,"(.*?)(?:\||\z)",3)
$td=TimerDiff($timer)
ConsoleWrite($td&" Reg Exp"&@Lf)
$split=""
$timer=TimerInit()
$split=StringSplit($string,"|")
$td=TimerDiff($timer)
ConsoleWrite($td&" Stringsplit"&@Lf)

[JackDinn]

yep all 3 do the job , n1 to you to

what a headache of a command

aye almost twice as fast to use stringsplit but then again thats what it was built for. but all good learning.
