[REGEX] Complex string to be validated

Recommended Posts


Hello, i need to validate a string can be different things. I just need a True - False return value, no groups or things like that. It will be always one line at time to be processed by StringRegEx


02:52 XX|String
13:52~SUN, MON, TUE, WED, THU, FRI, SAT|String
02:52 XX~SUN, MON, FRI|String
22/04/2017 13:52|String
22/04/2017 02:52 YY|String

Not Valid
22/04/2017 13:52~Dom|String

I need to validate until and inclusively the | after that i don't care

The XX and YY value are two $sVariable from my script

SUN, MON, TUE, WED, THU, FRI, SAT are fixed value, the can be mixed but always in the same order like




The time can be 12 or 24 hours, the date is always in the same format DD/MM/YYYY. If there is a date can't be a day after that ( see not valid )

Well i think is all :D

Sorry if i don't provide a working code, regex is too way complex.

Try this:

Local $aIn = [ _
    "13:52|String", _
    "02:52 XX|String", _
    "13:52~SUN, MON, TUE, WED, THU, FRI, SAT|String", _
    "22/04/2017 13:52|String", _
    "22/04/2017 02:52 YY|String", _
    "22/04/2017 13:52~Dom|String", _
    "13:72|String", _
    "33:12|String", _
    "13:52~ WED, THU|String", _
    "22/14/2017 13:52|String", _
    "62/04/2017 13:52|String", _
    "22/04/2117 13:52|String" _

Local $sVarXX = "XX", $sVarYY = "YY"

; Let's avoid painful repetition of sub patterns
; (?(DEFINE) (?<Time>   (?:[01]\d | 2[0-3]) : [0-5]\d ) )                   ; subroutine for hh:ss
; (?(DEFINE) (?<Day>    SUN | MON | TUE | WED | THU | FRI | SAT) )          ; subroutine for one day name
; (?(DEFINE) (?<Daylist> (?&Day) (?:,\ (?&Day))* ) )                        ; subroutine for a list of days
; (?(DEFINE) (?<Date>   (?:[0-2]\d|3[0-1]) / (?:0\d|1[0-2]) / 20\d\d\ ) )   ; subroutine for dd/mm/20xx (I choose to restrict YYYY to 2000..2099 but your app may need otherwise)
; Now we can sew all the pieces together, in the order of cases in $aIn
; (?x) allows ignoing non-escaped whitespaces in the pattern for improved readability
;"(?x) ^                                            ; anchor at start of string
;        (                                          ; group the pieces ORed (outer alternation)
;        (?&Time)                                   ; time alone
;        |                                          ; or
;        (?&Time) \ \Q" & $sVarXX & "\E             ; time space XX

;        |                                          ; or
;        (?&Date) (?&Time) \                        ; date space time
;        |                                          ; or
;        (?&Date) (?&Time) \ \Q" & $sVarYY & "\E    ; date time space XX
;        )                                          ; end of alternation
;\|"                                                ; final bar
; Smoke test:

Local $sPattern = _
    "(?x)" & _
    " (?(DEFINE) (?<Time>   (?:[01]\d | 2[0-3]) : [0-5]\d ) )" & _
    " (?(DEFINE) (?<Day>    SUN | MON | TUE | WED | THU | FRI | SAT) )" & _
    " (?(DEFINE) (?<Daylist> (?&Day) (?:,\ (?&Day))* ) )" & _
    " (?(DEFINE) (?<Date>   (?:[0-2]\d|3[0-1]) / (?:0\d|1[0-2]) / 20\d\d\ ) )" & _
    "" & _
        "^" & _
        " (?:" & _
            " (?&Time)" & _                                     ; time alone
            " | " & _                                           ; or
            " (?&Time) \ \Q" & $sVarXX & "\E" & _               ; time space XX
            " | " & _                                           ; or
            " (?&Time) ~ (?&Daylist)" & _                       ; time tilde daylist
            " | " & _                                           ; or
            " (?&Date) (?&Time)" & _                            ; date time
            " | " & _                                           ; or
            " (?&Date) (?&Time) \ \Q" & $sVarYY & "\E" & _      ; date time space XX
        ")" & _
    "\| .*"

For $s In $aIn
    ConsoleWrite('"' & $s & '" is ' & (StringRegExp($s, $sPattern) ? '' : 'in') & 'valid' & @LF)

      I have an XML file and every time there are three lines in a row with only <null/> in them, i want to insert a fourth line with <null/>.   Each line starts with 3 white spaces, followed by <null/> and ends with a white space followed by CR LF.   The presence of the three lines as described is unique to the points where I want to insert a line in this document.
       I'm trying to figure out how to apply the repeating part of a regex  {1,4} but apply it to this whole segment. 
      So far I have the below which picks up an individual line ok:
      ^\s{3}<null/>\s\r\n I tried wrapping it all in braces () then adding {3} but I'm obviously getting something wrong. 
      Attached is a section from the xml file with a block of nulls that should be matched if anyone would like to have a look.

      Hi All,
      I'd like to replace 'COMMA' with ',' for example:
      $myString = "COMMA" StringRegExpReplace($myString, 'COMMA', ',') Now I've tried escaping the ',' in various ways unsuccessfully, such as:
      [,] seems to work in the pattern, I just can't figure out how to use it in the replace, and it seems everyone online is only interested in removing/replacing commas lol.
      I also tried creating and using a variable as the replacement but also didn't work:
      $myComma = "," $myString = "COMMA" StringRegExpReplace($myString, 'COMMA', $myComma) I'm sure it's super simple if someone could point me in the right direction - thanks.

      Hi all,
      I still suck at regex as always and I need some help. According to the regex tester I normally use this should be working fine but it doesn't....
      StringRegExp($sString, "\A[1-9]+[0-9]*(\-[1-9]+[0-9]*)?,*\Z") I basically want to match:
      all numbers EXCEPT 0, but including 10, 20, etc with each number separated by a comma and allowing a "-" separated range as a value For example:
      1-5,7,10-12 I've spent a couple hours modifying it but I'm not sure where I've gone wrong. Any help would be appreciated!

      I need a little bit help from some RegEx experts please:
      I would make my ISN AutoIt Studio faster when generating the scripttree. And what would be better to do this via regex?
      Problem is i am not really good at this regex stuff. So maybe someone could help me here.
      The challange is to get all Global Variables from a script via RegEx in a Array.
      Here is a example script with some tests:
      Global $Var1 = 1234 Local $Local_Var = 1234 $Ignore_me_too = 1234 Global $Var2 = 1234, $var3 = 1242 Global $ahIcons[30], $ahLabels[30] Global Const $Var4 = iniread($inivar1,"jj","jj","") , $var5= iniread($inivar2,"jj","jj","") Global $Var_String = "was" Global $Array_Test[16] = [1,15,16,0,31,15,25,15,25,30,8,30,8,15,1,15] Global Enum $MARGIN_SCRIPT_NUMBER = 0, $MARGIN_SCRIPT_ICON, $MARGIN_SCRIPT_FOLD Global Const $Delim = '\', $Delim1 = '|' Global $hard1 = "a", _ $hard2 = "b", _ $hard3 = "c"  
      The returning array should look like this:
      $Var1 $Var2 $var3 $Var4 $var5 $Var_String $Array_Test $MARGIN_SCRIPT_NUMBER $MARGIN_SCRIPT_ICON $MARGIN_SCRIPT_FOLD $Delim $Delim1 $hard1 $hard2 $hard3  
      I already made some success with a expression i found in the SciTE Jump Tool:  (\$\w+)(?:[\h\[.=+*/^,)\-])?
      This nearly returns the perfect results. But it does not check if it´s a global variable (with the const and enum options) and also returns variables in commands (for example $inivar1)
      I also found this regex: (?im:^(?=Global|Const|Enum|Static)(?:Global)?\h*(?:Const|Enum|Static)?(?:(?<=Enum)\h+Step\h+[+*-]\d+)?\h*)([^\r\n .\=]+)
      This returns also usefull results...but trying to understand this explodes my head

      Maybe someone can help me here?
      Thanks in advance!
