hello, im having trouble detecting a string with regular expressions, here is my code

$linestringdel = '<script type="text/javascript">'

$findanuncios = StringRegExp($line, '(?s).*?(' & $linestringdel & ').*?', 0, 1)


But this wont find the line, 

$linestringdel = 'function killCopy(e){'

$findanuncios = StringRegExp($line, '(?s).*?(' & $linestringdel & ').*?', 0, 1)

im assuming its because of  '{' but im not sure as im still learning regular expressions but i got stuck with this one for a while now

Try this way:

$linestringdel = '<script type="text/javascript">'
$findanuncios = StringRegExp($line, '(?s)\Q' & $linestringdel & '\E')

$linestringdel = 'function killCopy(e){'
$findanuncios = StringRegExp($line, '(?s)\Q' & $linestringdel & '\E')

It isn't completely failproof but it will work with the examples given and much more, as long as the searched string doesn't contain \E itself.

line is the same string to search

$line = '<script type="text/javascript">'
$linestringdel = '<script type="text/javascript">'

$findanuncios = StringRegExp($line, '(?s).*?(' & $linestringdel & ').*?', 0, 1)

If $findanuncios = 1 Then
    MsgBox(0, "found", $line)
EndIf


$line = 'function killCopy(e){'
$linestringdel = 'function killCopy(e){'

$findanuncios = StringRegExp($line, '(?s).*?(' & $linestringdel & ').*?', 0, 1)

If $findanuncios = 1 Then
    MsgBox(0, "found", $line)
EndIf

tanks it worked

$line = '<script type="text/javascript">'
$linestringdel = '<script type="text/javascript">'

$findanuncios = StringRegExp($line, '(?s)\Q' & $linestringdel & '\E')

If $findanuncios = 1 Then
    MsgBox(0, "found", $line)
EndIf


$line = 'function killCopy(e){'
$linestringdel = 'function killCopy(e){'

$findanuncios = StringRegExp($line, '(?s)\Q' & $linestringdel & '\E')

If $findanuncios = 1 Then
    MsgBox(0, "found", $line)
EndIf
