_GUICtrlListView_AddItem manipulate record StringRegExp

5 posts in this topic

$text = 'C:\xxx\hh\hhhh\hhh\image.JPG'
$out  = StringRegExp($text,'.*\\(.*)\\',1)

Return the last folder hhh.

I would use this expression in the cycle below.
 

Local $aArray = _FileListToArrayRec("C:\test\app", "*app.exe", $FLTAR_FILES, 1, $FLTAR_SORT,$FLTAR_FULLPATH)

$fileArray = UBound($aArray) -1
    For $y = 1 To $fileArray
        _GUICtrlListView_AddItem($ListView,  StringRegExp($aArray[$y],'.*\\(.*)\\',1), 0)
    Next

 My target is to remove everything from the path, and take only the last folder.

Thanks

Should work with recent version (untested).

StringRegExp returns an array and your code needs a string then you also could use StringRegExpReplace

$text = 'C:\xxx\hh\hhhh\hhh\image.JPG'
$out  = StringRegExpReplace($text, '.*\\(.*)\\.*', "$1")
msgbox(0,"", $out)

Thanks guys, perfect. One more question, between the two methods which one is more powerful?

I don't understand 'powerful'
Meaning speed, the SRER may be a little slower because of the backreferencing but the difference is anecdotic if the expression is built for this purpose (the SRE could also be modified though)  :)

$text = 'C:\xxx\hh\hhhh\hhh\image.JPG'

$t1 = TimerInit()
For $i = 1 to 10000
  $out  = StringRegExpReplace($text, '.*\\([^\\]+)\\[^\\]*', "$1")
Next
$r1 = TimerDiff($t1)

Sleep(100)
$t2 = TimerInit()
For $i = 1 to 10000
  $out  = StringRegExp($text, '.*\\(.*)\\', 1)[0]
Next
$r2 = TimerDiff($t2)

Msgbox(0,"", "$out1 = " & $r1 & @crlf & "$out2 = " & $r2)

      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.

      Hello,
      I have spent the past day fooling with StringRegExp to no avail attempting to get what would be a simple solution to an issue using StringRegExp.
      I will post the code in a sec. The string 'Java x Update y' where x and y are numeric values ONLY if a letter is mixed in anywhere then it should fail. I have been able to successfully deal with the x value so if x = 1234 or a1234 or 1a234 or 1234a would result in a fail if 'a' was in the string. However, when y = 1a234 then I get an output of 1 and when y = 1234a then the output = 1234 when both should fail. I am probably overlooking something simple and in looking through all the material and experimenting I am unable to figure it out and my experience with stringregexp and trying to find examples of this proved difficult. If someone could assist or point me to a thread ? Here is my code ; prob a simple fix. I am also trying to avoid white spaces.
      Thanks in advance
      #include <array.au3> $aArray = StringRegExp('Java 3009 Update 1a21', '(?i)Java (\d+) Update (\d+)', $STR_REGEXPARRAYGLOBALMATCH) If @error Then Exit _ArrayDisplay($aArray)

      Does anyone know how to split a string using multiple delimiters, returning both the values and delimiters withing the Array using StringRegExp?  For example:
      ;~ Split on " Not ", " And ", " Or " $sString = ' Not $a = 1 And $b = 2 Or $b = 3' $aArray = StringRegExp($sString,...) ;~ Returned Results $aArray[0] = '$a = 1' $aArray[1] = 'And' $aArray[2] = '$b = 2' $aArray[3] = 'Or' $aArray[4] = '$b = 3' At the moment I'm using
      Local $aArray1 = StringRegExp($sString, '(?i) Or | And | Not ', 3) Creating a new array using string split and then joining the two arrays together again
      Local $aArray1 = StringSplit(StringRegExpReplace($sString, '(?i) Or | And | Not ', '******'), '******', 3) Unfortunately regular expression isn't my forte.
