StringRegExp - I cracked it... except i didn't.

[Maffe811]

So after my overcomplicated stringregexp funciong worked i decided to make it less complicated.

and so i did.

I went from

Func _Stringifier($Link)
Local $Counter
Local $Feedback
Local $ArraySize
Local $Array[2]
Local $CutValue
Local $String

;~ $Link = "http://www.stanceworks.com/wp-content/themes/saviour/images/graphics/stanceworks-twitter.png"
$Pattern = "(/*.)?"


$Array = StringRegExp($Link, $Pattern, 3)
;~ _ArrayDisplay($Array)

$ArraySize = (UBound($Array) - 1)

;~ MsgBox("","",$ArraySize )
For $Counter = $ArraySize To 0 Step -1
$Feedback = StringInStr($Array[$Counter], "/")
;~ ConsoleWrite("!" & $Counter & "-" & $Array[$Counter] & ": " & $Feedback & @CRLF)
If $Feedback = 1 Then ExitLoop
Next

;~ MsgBox("","",$Feedback)
;~ MsgBox("","",$Counter)

$CutValue = $ArraySize - $Counter

;~ MsgBox("","",$CutValue)
$String = StringRight($Link, $CutValue)
;~ MsgBox("","",$String)
Return $String
EndFunc ;==>_Stringifier

to

Func _Stringifier($Link)
Local $Pattern
Local $Array
Local $String

;~ $Link = "http://www.stanceworks.com/wp-content/themes/saviour/images/graphics/stanceworks-twitter.png"

;~ MsgBox("", "", $Link)
$Pattern = "w*b.jpg"
$Array = StringRegExp($Link, $Pattern, 1)

If $String = 1 Then
$Pattern = "w*b.png"
$String = StringRegExp($Link, $Pattern, 1)
Else
ConsoleWrite("File .jpg" & @CRLF)
EndIf

If $String = 1 Then
ConsoleWrite("File not jpg/png" & @CRLF)
Else
ConsoleWrite("File .png" & @CRLF)
EndIf

For $i = 0 To UBound($Array) - 1
;~ MsgBox("", "", "String: " & $Array[$i] & @CRLF & "Ubound: " & UBound($Array) - 1 & @CRLF & "$i: " & $i)
$String = $Array[$i]
Next

Return $String
EndFunc ;==>_Stringifier

So if i fix the pattern i can remove alot of stuff.

the pattern w*b.jpg worked for some time, except that it is also stopping on dashes ( - )

How can i add that to the pattern?

Like look for word but also dashes ? [w -]?

Also, how can i get it to search for .jpg or .png ?

I tried [(.jpg)(.png)] but i didn't get this to work

Edit:

Can i use the "|" to do this?

.jpg|,png ? or (.jpg|.png)?

Am i even close?

You could use [w-]+ but why bother for what you are testing?

Unless I misunderstood the problem; all you want to know is if it's either jpg or png

If StringRegExp($s_Test, "(?i).jpg|.png") Then
ConsoleWrite("File is type: " & StringRegExpReplace($s_Test, ".+.(.+)b", "$1") & @CRLF)
Else
ConsoleWrite("File is not of type jpg or png" & @CRLF)
EndIf

You should also take a closer look at what the flags do. You don't need a flag at all (or use 0) to test for True and False.

you misunderstood

What i want is this:

to become this:

accuair-stanceworks-avila-car-show-title.jpg

But currently it crashes with dashes -

so i only get:

title.jpg

and some are .jpg and some are .png

So the pattern would be find whats between .jpg/png and a slash.

[GEOSoft]

.+/(.+.png|.+.jpg).*

You could also use an SRE replace to get the filename.

$s_Name = StringRegExpReplace($s_Str, ".+?/(.+.)(png|jpg).*, "$1$2")

.+/(.+.png|.+.jpg).*

This works perfectly!

But, would you care to explain how it works so i can see if i can actually learn this?

You could also use an SRE replace to get the filename.

$s_Name = StringRegExpReplace($s_Str, ".+?/(.+.)(png|jpg).*, "$1$2")

I belive you missed a " at the end of the pattern, so i added that.

But it removes http, but i have no idea on how to fix it.

[GEOSoft]

To fix the srer just remove the "?"

The regexp matches everything up to the last "/" then captures everything after that as long as it ends in png or jpg,

Tip: Add "(?i) to the front of bothe the sre and the srer for safety sakes since the odd idiot uses caps in extensions.

The regexp matches everything up to the last "/" then captures everything after that as long as it ends in png or jpg,

So .+/ means everything before a slash

(.+.png|.+jpg) means everything before .png.jpg, but after all the slashes? (This is what it returns, is that cause its in parentheses?)

.* is just to include anything else behind that ?

Tip: Add "(?i) to the front of bothe the sre and the srer for safety sakes since the odd idiot uses caps in extensions.

Okay, thanks!
