RegExp - How To Replace Every Other Quote Found?

Hi all,

So, I have strings where I'm trying to delimit each value, that's currently separated with spaces, with a pipe. Here are a few of the strings:

"webstratauthentication\enableuserpasswordencryption.sql"02/23/2011  01:17:22 PM         1401  "12312312312312312""A"           "b04ecbc4-e0e2-c14b-d780-656d348b0513"  "\\nas123456n\ct40_packaging\builds\product\productname\hss\authentication\enableuserpasswordencryption.sql"
        "webstratauthentication\enableuserpasswordencryption.sql"02/23/2011  01:17:22 PM         1401  ""                 "A"           "b04ecbc4-e0e2-c14b-d780-656d348b0513"  "\\nas123456n\ct40_packaging\builds\product\productname\hss\authentication\enableuserpasswordencryption.sql"
        "ikernel.dll"                                           04/26/2002  07:48:38 PM            0  ""                 "A"           "d98c1dd4-008f-04b2-e980-0998ecf8427e"  "c:\program files\installshield 10.5\support\build\ikernel.dll"

I'd like to return the strings looking like this:

"webstratauthentication\enableuserpasswordencryption.sql"|02/23/2011|01:17:22 PM|1401|"12312312312312312"|"A"|"b04ecbc4-e0e2-c14b-d780-656d348b0513"|"\\nas123456n\ct40_packaging\builds\product\productname\hss\authentication\enableuserpasswordencryption.sql"
"webstratauthentication\enableuserpasswordencryption.sql"|02/23/2011|01:17:22 PM|1401|""|"A"|"b04ecbc4-e0e2-c14b-d780-656d348b0513"|"\\nas123456n\ct40_packaging\builds\product\productname\hss\authentication\enableuserpasswordencryption.sql"
"ikernel.dll"|04/26/2002|07:48:38 PM|0|""|"A"|"d98c1dd4-008f-04b2-e980-0998ecf8427e"|"c:\program files\installshield 10.5\support\build\ikernel.dll"

I've tried replacing the double spaces with pipes, but that messes up the first string and leaves "12312312312312312""A" without adding the pipe between the two values.

$sLine = StringRegExpReplace($sLine, "[ ]{2,}", "|")

So, I concocted a way to do it with a string-based approach.

; Strip the leading and trailing ws
$sTempLine = StringStripWS($sTempLine, 1 + 2)
; Replace all double spaces with pipes
$sTempLine = StringRegExpReplace($sTempLine, "[ ]{2,}", "|")
If StringInStr($sTempLine, '""A"') > 0 Then
    $sTempLine = StringReplace($sTempLine, '""A"', '"|"A"')
EndIf
; And check if the file name needs a pipe after its second double quote
$iPos = StringInStr($sTempLine, '"', 0, 2)
If StringMid($sTempLine, $iPos, 2) <> '"|' Then
    $sTempLine1 = StringMid($sTempLine, 1, $iPos)
    $sTempLine1 &= "|" & StringMid($sTempLine, ($iPos + 1), (StringLen($sTempLine) - $iPos))
    $sTempLine1 = StringReplace($sTempLine1, '" "', '"|"')
    $sTempLine = $sTempLine1
EndIf
ConsoleWrite("-> " & $sTempLine & @CRLF)

Is there a better regex that I can use to separate these values in the strings with pipes? I thought that it might be easiest to just put a pipe after every second quote...

Thank you for the help.

One of the problems with your text is that there aren't any spaces between "12312312312312312" and "A", or between "webstratauthenticationenableuserpasswordencryption.sql" and 02/23/2011. You might have to do it with 2 passes, as I don't know that a single one will work.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

Answering the question in the title. You don't need a regular expression for this. You can use StringSplit() with quote as delimiter. Loop through the array and reinsert quote at the start of every other element.

Ok, I found a way to do it through string functions. It works, but it's just not as magical as a regex :idiot:

I was always under the impression that using regex would work much faster than the below code.

#include <String.au3>
Dim $aLine[3], $aGood[3]
$aLine[0] = '       "webstratauthentication\enableuserpasswordencryption.sql"02/23/2011  01:17:22 PM         1401  "12312312312312312""A"           "b04ecbc4-e0e2-c14b-d780-656d348b0513"  "\\nas123456n\ct40_packaging\builds\product\productname\hss\authentication\enableuserpasswordencryption.sql"'

For $i = 0 To UBound($aLine) - 1
    $b = False
    $aLine[$i] = StringStripWS($aLine[$i], 1 + 2)
    $aLine[$i] = StringRegExpReplace($aLine[$i], "[ ]{2,}", "|")
    For $j = 1 To StringLen($aLine[$i])
        If StringMid($aLine[$i], $j, 1) = '"' And $b = False Then
            $b = True
        ElseIf StringMid($aLine[$i], $j, 1) = '"' And $b = True Then
            $b = False
            If StringMid($aLine[$i], ($j + 1), 1) <> '|' Then
                ConsoleWrite("Before (" & $j &"): " & $aLine[$i] & @CRLF)

    EndIf

RegExp is slow, slower than most string functions, but invaluable when you have something tricky to split up/find. Practically useless when the data isn't consistent though. Best advice, learn when NOT to use RegExp.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

not true, is completely contrary, today without RegExp, will be unable to do anything, or better to say the ratio of the speed is 1-1000 if you check the files 1-10 Mb, not to mention other after etc etc etc, even users that working in C++11 (Machine Code ehhhh), which (regarding the speed) can certainly do without RegEx, they too today thank RegEx, because thanks to the RegEx also in C++ itself performance have grown much

Using 2 passes is much easier  :)

      Problem with regexp after updating autoit
      By PClough
      Hi everyone!
      After updating autoit, I tried to run an old program using complex regexp's.  It did not work.  Eventually I broke the problem down to this example:
       
      #include <Array.au3> $buf = "First title" & @CRLF & "Tom" & Chr(0x92) & "s sleepwalking" & @CRLF & "Last | line" & @CRLF $items = StringRegExp($buf, '([\x20-\xff]+)\x0d\x0a', 3) _ArrayDisplay($items,'') And this is the result I get when running it:
      Row 0

      Use RegExp on binary data
      By Robinson1
      Well the plan is to use the power of regular expressions engine of AutoIT for patching binary data.
      Something like this: StringRegExp( $BinaryData,  "(?s)\x55\x8B.."
       
      <cut> ... Okay straight to question/problem
      ... certain bytes that are in the range from 0x80 to 0xA0 won't match.
      Hmm seem to be a char encoding problem. In detail these are 27 chars: 0x80, 0x82~8C, 0x8E, 0x91~9C, 0x9E,0x9F
      Here's a small code snippet to explore / explain this problem:
      #include "StringConstants.au3" $TestData = BinaryToString("0x7E7F808182") ;Okay $match = StringRegExp( $TestData ,'\x7E' ,$STR_REGEXPARRAYFULLMATCH) ConsoleWrite('@extended = ' & @extended & ' $match = ' & $match & @CRLF) ;Okay $match = StringRegExp( $TestData ,'\x7F' ,$STR_REGEXPARRAYFULLMATCH) ConsoleWrite('@extended = ' & @extended & ' $match = ' & $match & @CRLF) ;Error no match $match = StringRegExp( $TestData ,'\x80' ,$STR_REGEXPARRAYFULLMATCH) ConsoleWrite('@extended = ' & @extended & ' $match = ' & $match & @CRLF) ;Okay $match = StringRegExp( $TestData ,'\x81' ,$STR_REGEXPARRAYFULLMATCH) ConsoleWrite('@extended = ' & @extended & ' $match = ' & $match & @CRLF) ;Error no match $match = StringRegExp( $TestData ,'\x82' ,$STR_REGEXPARRAYFULLMATCH) ConsoleWrite('@extended = ' & @extended & ' $match = ' & $match & @CRLF) ;~ output: ;~ @extended = 2 $match = ;~ @extended = 3 $match = ;~ @extended = 0 $match = 1 ;~ @extended = 5 $match = ;~ @extended = 0 $match = 1 Hmm what to do? Go back and use the 'numberstring monster' implementation or just omit that range of 'unsafe bytes'. What is the root of this problem?
      Any idea how to fix this?
       
      Update: Okay I know a byte is not a character.
      But StringRegExp operates on String and so character level.
      Okay as long as you stay at Ansi encoding and only use /x00 - /X7F in the search pattern using  StringRegExp works well to search for binary data.
      What bytes can be matched that are in the range from /X7F - /xFF is also depending on the code page.
      So this avoid to search for bytes in the range from 0x80-0xa0 only applies to Germany.
      I just change this country setting:

      to Thai and now near all bytes from /X7F - /xFF fails to match.

      Regular Expression to select text over multi-lines
      By RichardL
      Text in a file, read into var with fileread:
      <> <> <> <> < J please look > <> <> <> Hi, 
      I want  a RegExp to select around 'please', back to the previous < and forward to the next >.  I can select the line of text.  Then I add in (?s) and it selects the whole text.  I think I want to make it not greedy, (?U) , that seems to make it ungreedy after, but it still selects all the previous lines.
      $sPattern = "(?s)<.*please.*>" ; 1 $sPattern = "(?s)<(?U).*please.*>" ; 2 $sPattern = "(?s)<(?U).*please(?U).*>" ; 3 $sAry = StringRegExp($sHTML, $sPattern, 3)
