What is the best way to check for 3 pieces of text in a string?

[careca]

Hi, im struggling with this issue, StringInStr could do the trick, but it doesn't seem to support 3 different strings to compare, StringRegExp is messy, i tried some ways, help was no help, so i hope you can.

So this will exemplify what i need:

$StrDropCheckFolder = StringInStr($__aGUIDropFiles[$i], ".mp3;.wav;.wma", 2)

Anything that contains those = true

I made the StringRegExp work, but only with one string at a time.

Couldn't find in help file the corresponding OR parameter.. and OR doesn't work in StringInStr.

Best regards.

Have you considered reversing the logic? IE: Get the extension of the file and use that to search against ".mp3;.wav;.wma".

In StringRegExp, pipe is used for OR. ==> ".mp3|.wav|.wma"

Something like this ?

Local $aFiles[] = [ "1.mp3", "2.txt", "3.wav", "4.wma", "5.doc"]
For $i = 0 To UBound($aFiles) - 1
    If StringRegExp($aFiles[$i], "(?i)\.(?:wav|mp3|wma)$") Then ConsoleWrite($aFiles[$i] & @CRLF)
Next

Hi, thank you all, it is exactly that, now i've been looking at the help file, and what "czardas" posted is what is called a "Non-capturing group with reset" yes?

and what "jguinch" posted is a "Non-capturing group", have to be honest, i've seen them in the help file, but didn't have a clue it was what i was looking for.

Also im trying to understand what is what, and i've used (?i) to make whats next to it case in-sensitive, but why is "." this used between it and the grouped items?

About the $ at the end.. help file says: "Outside a character class, the dollar matches at the end of the subject text, and also just before a newline sequence if option (?m) is active."

So, like a final dot in a sentence?

Thanks

EDIT: after looking at it again, it seems the trailing backlash represents whats before the dot, and the dot, represents the extension dot, and is where it is, because it is common to the text in the group.

About the $ at the end of the pattern, just try this with and without the $ 

$str = "test.mp3.bak"
Msgbox(0,"", StringRegExp($str, "(?i)\.(?:wav|mp3|wma)$") )

Yes, with it, it only searches the last bit, without it, searches all. Thank you
