Regex with Variable


Recommended Posts

Hey there, my problem is that the Substring im looking for in my  Mainstring is changing a lot. 

So for example: 

$aRes = StringRegExp($text,$substring, 3)
FileWrite("found.txt", _ArrayToString($aRes, @crlf))

this returns just -1 while this:

$aRes = StringRegExp($text,"hello", 3)
FileWrite("found.txt", _ArrayToString($aRes, @crlf))

returns my the full array. What am I doing wrong?

A string witch has been read out by teserract.exe

I think i found the problem, the string which came from teserract is smaller than the same word in the mainstring. Any solutions for that? For me they seem to be identical

I think you just have to use :

$aRes = StringRegExp($text, "\Q" & $substring & "\E", 3)

but we cannot help you if you don't provide us an example of the content stored in $substring and $text

Here is the code im talking about:

func tesseract()
_ScreenCapture_Capture(@DesktopDir&"\Image1.jpg",1223, 452,1647, 509)
Local $img_filename = "C:\Users\bla\Desktop\Image1.jpg"
$ocr_filename = "C:\Users\bla\Desktop\Image1"
$ocr_filename_and_ext ="C:\Users\bla\Desktop\Image1.txt"
Local $iPID = Run(@ComSpec & " /C " & "tesseract.exe """ & $img_filename & """ """ & $ocr_filename & """", @ProgramFilesDir & "\Tesseract-OCR", @SW_HIDE, $STDERR_CHILD + $STDOUT_CHILD)
ProcessWaitClose($iPID)
FileOpen($ocr_filename_and_ext)
$a1= FileRead($ocr_filename_and_ext)
FileClose($ocr_filename_and_ext)
EndFunc

tesseract()

FileWriteline("bla.txt",$a1)
FileClose("bla.txt")

FileOpen("bla.txt")
$substring = FileRead("bla.txt")
FileClose("bla.txt")


$compare = StringCompare($substring,"string")
ConsoleWrite($compare)

Isn't this the same script you are already asking for help with? If you can't get it to work, how do you expect it to compare 2 strings? You can't even get the text of the first string according to the other thread you have going, so I can't see how it would ever work in this instance

 

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.

BTW, have you tried the Tesseract UDF?
