RegEx and MAC Address

Recommended Posts

Regular expressions, I hate them, seriously  :ranting:

I have a MAC address in this format:

"A2B3B56B7C3A"

And I would like to change it in:

"A2-B3-B5-6B-7C-3A"

The MAC address can be a little longer than that one, but we are sure that the total digit number is an even number.

I've tried a lot of patterns but I have not tried the right one.

This is the closest one I've tried but the output shows a final hyphen (I could cut it through StringTrimLeft but I would like to do it using just RegEx).

ConsoleWrite(StringRegExpReplace("A2B3B56B7C3A", "(.{2})", "$1-"))

I don't understand why this pattern doesn't work :(

ConsoleWrite(StringRegExpReplace("A2B3B56B7C3A", "^(?:.{2})(.{2})+?", "-$1"))

Thanks in advance  ^_^

Two steps, but could you will find someone widdle it down to 1:

$string = "A2B3B56B7C3A"
$a = StringRegExp($string,"(\w{2,2})",3)
$mac = _ArrayToString($a,"-")
ConsoleWrite($mac & @CRLF)

I have no idea why _ArraytoString is byref...let's remove that:

$string = "A2B3B56B7C3A"
$mac = _ArrayToString2(StringRegExp($string,"(\w{2,2})",3),"-")
ConsoleWrite($mac & @CRLF)


Func _ArrayToString2($avArray, $sDelim = "|", $iStart = 0, $iEnd = 0)
    If Not IsArray($avArray) Then Return SetError(1, 0, "")
    If UBound($avArray, 0) <> 1 Then Return SetError(3, 0, "")

    Local $sResult, $iUBound = UBound($avArray) - 1

    ; Bounds checking
    If $iEnd < 1 Or $iEnd > $iUBound Then $iEnd = $iUBound
    If $iStart < 0 Then $iStart = 0
    If $iStart > $iEnd Then Return SetError(2, 0, "")

    ; Combine
    For $i = $iStart To $iEnd
        $sResult &= $avArray[$i] & $sDelim
    Next

    Return StringTrimRight($sResult, StringLen($sDelim))
EndFunc   ;==>_ArrayToString

The output for the string is the same, but the pattern is not.  Although {2} and {2,2} is the same.

Like I said, someone will get it down to one function.  Not me.

      Inspired by PHP's preg_split.
      Split string by a regular expression.
      Also supports the same flags as the PHP equivalent.
      v1.0.1
       
      Example:
      #include "StringRegExpSplit.au3" StringRegExpSplit('splitCamelCaseWords', '(?<=\w)(?=[A-Z])') ; ['split', 'Camel', 'Case', 'Words']

      #include <IE.au3> $oIE = _IEAttach ("Edu.corner") Local $aName = "Student name & Code:", $iaName = "0" Local $oTds = _IETagNameGetCollection($oIE, "td") For $oTd In $oTds If $oTd.InnerText = $aName Then $iaName = $oTd.NextElementSibling.InnerText $iGet = StringRegExpReplace($iaName, "\D", "") EndIf Next MsgBox(0, "", $iGet) it was get number like 52503058
      But, I want to get only student code 5250. (Different student have different code, sometime its 3 digits, Sometime 4)

      Is there a way to output the regex matches into a file?
      I have a script to compare two files and check for regex matches.
      I want to output the matching regex of 'testexample.txt' to another file.
      #include <MsgBoxConstants.au3> #include <Array.au3> $Read = FileReadToArray("C:\Users\admin\Documents\testexample.txt") $Dictionary = FileReadToArray("C:\Users\admin\Documents\example.txt") For $p = 0 To UBound($Dictionary) - 1 Step 1 $pattern = $Dictionary[$p] For $i = 0 To UBound($Read) - 1 Step 1 $regex = $Read[$i] If StringRegExp($regex, $pattern, 0) Then MsgBox(0, "ResultsPass", "The string is in the file, highlighted strings: " ) Else MsgBox(0, "ResultsFail", "The string isn't in the file.") EndIf Next Next

      I am using positive look behind.:
      (?<=FILM|WOUND|OXIDE).+ Can only pull this off:

      I am adding labour charge to total paid amount using : 
      #include <IE.au3> #include <Array.au3> $oIE = _IEAttach ("Shop") $oTable = _IETableGetCollection ($oIE, 1) $aTableData3 = _IETableWriteToArray ($oTable) Local $sitem1 = $aTableData3[5][1] Local $sitem2 = $aTableData3[5][2] Local $lcharge = "10" ;add manualy using inputbox, becuase not generating online Local $atotPric = "Payable Total Price " Local $oTds = _IETagNameGetCollection($oIE, "td") For $oTd In $oTds If $oTd.Innertext = $atotPric Then $iatotPric = $oTd.NextElementSibling.innertext MsgBox (0, "2", $iatotPric) EndIf Next $irCtotal = StringFormat("%.2f", $sitem1 + $sitem2 + $lcharge) $crTotp = StringReplace(_IEBodyReadHTML($oIE), $iatotPric, $irCtotal) _IEBodyWriteHTML ($oIE, $crTotp) But, It was also changing Total price, I want to change only Payable Total Price.
