StringRegExp exact match

[david1337]

Hi guys

I hope you can help me out with this one.

I have a text file "test.txt" which could contain something like this:

__________________________________________________________

fiw
eqw
sdg
xcv

__________________________________________________________

Each string has it's own line.

 

I use this script to find a string in the text file.

In this example, the string I am looking for is "iw".
The string "fiw" makes it believe that "iw" is found in the file. How can I avoid this?
I want it only to return EXACT results.
 

$string = "iw"

$File = FileOpen("test.txt", 0)
$ReadFile = FileRead($File)
FileClose($File)

If StringRegExp(StringLower($ReadFile), StringLower($string)) Then

MsgBox(0,"",$string & " is found in the file")

Exit

Else

MsgBox(0,"",$string & " is not found in the file")

Exit

EndIf

david1337,

Use "beginning and end of string" anchors around the required string like this:

$string = "iw"

$ReadFile = "fiw" & @CRLF & "eqw" & @CRLF & "sdg" & @CRLF & "xcv"

If StringRegExp(StringLower($ReadFile), "^" & StringLower($string) & "$") Then
    MsgBox(0, "", $string & " is found in the file")
Else
    MsgBox(0, "", $string & " is not found in the file")
EndIf

Melba,
Please don't forget the (?m) option

Hi Melba

Thanks for your answer!
It seems that with your code, all strings gets the message "is not found in the file", even though I use "fiw" which is there?

david1337,

mikell had the answer - you need to be in multiline mode:

$ReadFile = "fiw" & @CRLF & "eqw" & @CRLF & "sdg" & @CRLF & "xcv"

$string = "iw"
If StringRegExp(StringLower($ReadFile), "(?m)^" & StringLower($string) & "$") Then
    MsgBox(0, "", $string & " is found in the file")
Else
    MsgBox(0, "", $string & " is not found in the file")
EndIf

$string = "fiw"
If StringRegExp(StringLower($ReadFile), "(?m)^" & StringLower($string) & "$") Then
    MsgBox(0, "", $string & " is found in the file")
Else
    MsgBox(0, "", $string & " is not found in the file")
EndIf

Sorry about that - I had tested for the "wrong" case, but not for "right" one.

That worked perfectly.

Thanks for taking your time Melba and mikell
