Regex cant find \n

[lordsocke]

Hey there, 

my code: 

Global $res = StringRegExp($text,"\n", 3)
If @error Then
    $nbOccurencesn = 0
Else
   $nbOccurencesn = UBound($res)
Endif
ConsoleWrite(@crlf&$nbOccurencesn&@crlf)

is not delivering any hits in the string:

"Which Reese Witherspoon movie\nhas gotten a Broadway musical\nadaptation?\nElection\nWalk the Line\nLegally Blonde\n"

any Ideas what im making wrong?

looking for a literal, and not escaping the character also used for pattern matching

$text = "Which Reese Witherspoon movie\nhas gotten a Broadway musical\nadaptation?\nElection\nWalk the Line\nLegally Blonde\n"

Global $res = StringRegExp($text,"\\n", 3)
If @error Then
    $nbOccurencesn = 0
Else
   $nbOccurencesn = UBound($res)
Endif
ConsoleWrite(@crlf&$nbOccurencesn&@crlf)

 

from helpfile:

Quote

\n	Represents "linefeed" (@LF, Chr(10)).

so thats what you were looking for and why a one line string would correctly return 0

Anyway the real purpose is hopefully different, because such a simple thing doesn't need a regex 

$text = "Which Reese Witherspoon movie\nhas gotten a Broadway musical\nadaptation?\nElection\nWalk the Line\nLegally Blonde\n"

$res = StringReplace($text,"\n", "\n")
;Global $res = StringRegExp($text,"\n", 3)
If not @extended Then ;@error Then
    $nbOccurencesn = 0
Else
   $nbOccurencesn = @extended ;UBound($res)
Endif
ConsoleWrite(@crlf&$nbOccurencesn&@crlf)

Endif
ConsoleWrite(@crlf&$nbOccurencesn&@crlf)

 

But the Thing is, that I need to keep the \n inside the code.
