Another Method

7 posts in this topic

Hello ,

Well guys i want to know any other Method to match the multiple strings in any target String.

e.g :

;I have 3 Stings in array
Dim $ar[6]=["A","B","C","the","fox","dog"]

;The target string
$String = "A quiCk Brown fox jumps over the lazy dog"

; Normal Method
For $i = 0 to 5

    if StringinStr($String,$ar[$i],2) then
        ConsoleWrite($ar[$i]&" > Matched In Target String"&@CRLF)
    endif

Next

So Is there any other method to match multiple strings in any target string.

i mean to say another method to do my required task ,without Loop.

Actually its take much time if the Array contain many strings.

Thanks in Advance.

#include <array.au3>
$pattern="A|B|C|the|fox|dog"
$String = "A quiCk Brown fox jumps over the lazy dog"
$a=StringRegExp($String,$pattern,3)
_ArrayDisplay($a)
Thanks Hubertus72,

Its Really Cool, Bundle of Thanks. :)

1. You can't open a binary file in the text read mode.

2. StringRegExp does not work with unicode chars.

You can use the hex syntax of stringregexp(): \x##

or using the binary fileread(). Here an example:

#include <array.au3>
$pattern="5F65786974|00052B" ;search for "_exit" or "0x00052B"
$h=FileOpen(@WindowsDir&"\system32\ping.exe",16) 
$String = FileRead($h)
FileClose($h) 
$a=StringRegExp($String,$pattern,3)
_ArrayDisplay($a)
Thanks Hubertus72 Your Solution is Really cool. Thank you all guys.

But that is wrong.

"5F65786974" may be "0x5F65786974" but may very well be a part of "0x65F657869742" and that is completely different.

That is searching string inside binary data and that's not right.

Special charaters can be included. Example:

#include <array.au3>
$pattern = Chr(65) & "|" & Chr(66) & "|" & Chr(67) & "|the|fox|dog"
$String = "A quiCk Brown fox jumps over the lazy dog"
$a=StringRegExp($String,$pattern,3)
_ArrayDisplay($a)

Your Rite,but in some cases(coz 0x5F65786974 is only used when you want to scan a file from its first bytes.), but my requirement is to scan a file from the bytes of EOF. So i just feed the data (pattern); from the EOF of any file. there is a simple but amaze thing that every file's bytes in EOF will diffrent(i got this experience after using a lot of Heckman HEX editor). so Hubertus72's method is exact what i want. anyways thanks.
