StringRegExpReplace Help pleae


Recommended Posts

Hello folks,

I must have a fundamental misunderstanding of classes and how they work in AutoIt regular expressions. I want to be able to determine how many alpha characters are in a string.

Here's a small test to show my difficulty.

test1() ;works, but nasty looking
ConsoleWrite(@CRLF)
test2() ;preferred "solution", but doesn't work.

func test1()
    Local $str = "(* test *)"
    ConsoleWrite($str  & @CRLF)
    $str = StringRegExpReplace($str, "[abcdefghijklmnopqrstuvwxyz]", "@")
    Local $repl = @extended
    ConsoleWrite($str  & @CRLF)
    ConsoleWrite($repl  & @CRLF)
EndFunc

func test2()
    Local $str = "(* test *)"
    ConsoleWrite($str  & @CRLF)
    $str = StringRegExpReplace($str, "[:alpha:]", "@")
    Local $repl = @extended
    ConsoleWrite($str  & @CRLF)
    ConsoleWrite($repl  & @CRLF)
EndFunc

Any help greatly appreciated.

RagsRevenge,

You need to place the Class inside a set like this:

test1() ;works, but nasty looking
ConsoleWrite(@CRLF)
test2() ;preferred "solution", but does work now!!!!

func test1()
    Local $str = "(* test *)"
    ConsoleWrite($str  & @CRLF)
    $str = StringRegExpReplace($str, "[abcdefghijklmnopqrstuvwxyz]", "@")
    Local $repl = @extended
    ConsoleWrite($str  & @CRLF)
    ConsoleWrite($repl  & @CRLF)
EndFunc

func test2()
    Local $str = "(* test *)"
    ConsoleWrite($str  & @CRLF)
    $str = StringRegExpReplace($str, "[[:alpha:]]", "@") ; <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
    Local $repl = @extended
    ConsoleWrite($str  & @CRLF)
    ConsoleWrite($repl  & @CRLF)
EndFunc

Used to catch me out a lot when I started with SREs. :)

You can specify character ranges as a class, so here's how I'd do it. This will match anything in the alphabet in either upper or lowercase.

StringRegExpReplace($str, "[A-z]", "")

I don't like using the :classes:, and I always use the above for stuff like this :)

Mat, the above will also catch these characters: [\]^_`

You should change it to "[A-Za-z]" or put a case-insensitive modifier with a single case range -> "(?i)[A-Z]"
