Request for mentoring on SRE

Recommended Posts

DxMxS

Hello Guys,

I recently discovered PCRE thanks to AutoIt.

Yesterday a couple fellows from this board taught me how to find a specific string, keep it and get rid of the rest of the content in an edit control.

Local $fwlID = StringRegExpReplace($eContent, '(?s).*?((FWLd*)|$)', '$2' & @crlf)

 

(In this case the strings I wanted to keep start with FWL followed by numbers).

Today I have a new challenge, there are duplicate FWL codes. I want to keep one ocurrence of each code and get rid of all duplicates.

I have done some research on the web and this forum but have not been able to find a solution.

Can someone please assist me and explain his/her proposed regEx for our future reference?

Thanks in advance!

DxMxS,

No need for a RegEx. Get the values into an array as I did in the code I posted and use _ArrayUnique to remove duplicates. ;)

Thanks Melba, I will definitely give that approach a try. However, I still would like to learn how to get the task done using a RegEx  :graduated:

DxMxS,

Beware of the facination of RegExes. As GEOSoft (who introduced me to them several years ago) used to say - one of the things you need to learn is when NOT to use them. RegExes are, by definition, used to to detect regularly occuring patterns in data - they are not designed to be a complete toolbox. In this case finding all lines that start "FWL" is exactly what they are meant for - detecting duplicates is another thing altogether. ;)

That said, one of the RegEx gurus will no doubt come along and post a solution in a minute! :D

Thanks Melba,

It is really good for me and my coding to learn in which scenarios a given approach is optimal and in which it is not. ^_^

I appreciate your comment.

DxMxS,
The regex Melba posted meant "find all matches" , the regexreplace I wrote meant "fire all but matches" , in both cases the approach is similar
Maybe what you want is possible using regex, but this looks like a headache to come while the simplest way is usually the best one
In this case Melba's solution does the job perfectly :)

#include <Array.au3>

$array = StringRegExp($text, 'FWL\d*', 3)
$new_array = _ArrayUnique($array)

Edit

Nonetheless ... :D

#include <GUIConstantsEx.au3>

$sText = "xxxxxxxxxxxxxxxxxxxxxxxxxxxx" & @CRLF & _
        "FWL12345" & @CRLF & _
        "FWL9875632" & @CRLF & _
        "yyyyyyyyyyyyyyyyyyyyyyyyyyyy" & @CRLF & _
        "FWL12345" & @CRLF & _
        "zzzzzzzzzzzzzzzzzzzzzzzzzzzz" & @CRLF & _
        "" & @CRLF & _
        "" & @CRLF & _
        "FWL45678965" & @CRLF & _
        "FWL12345" & @CRLF & _
        "FWL985612565" & @CRLF & _
        "bbbbbbbbbbbbbbbbbbbbbbbbb"

$hGUI = GUICreate("Test", 500, 500)
$cEdit = GUICtrlCreateEdit($sText, 10, 10, 480, 400)
$cButton = GUICtrlCreateButton("Filter", 10, 450, 80, 30)
GUICtrlSetState($cButton, $GUI_FOCUS)
GUISetState()

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $cButton
            Filter()
    EndSwitch
WEnd

Func Filter()
    $ret = StringStripWS(StringRegExpReplace(GuiCtrlRead($cEdit), '(?s).*?((FWL\d*)(?!.*\2.*)|$)', '$2' & @crlf), 3)
    GuiCtrlSetData($cEdit, $ret)
EndFunc

Sorry I forgot the explanation in my edit for the regex to remove duplicates

(?!.*2.*)  is a negative lookahead which means : "if the rest of the string doesn't contain the backreference #2 (that to say : the part matched)"
So the one retained among the duplicates will be the last one found

AZJIO - The 3RD parm for stringsplit should be "3" to use the whole split argument.

edit: How does the dictionary get connected to the array?
