I'm having problems while replacing metacharacters using regular expressions. The phrase I want the regular expressions replace the metacharacter is:
ley+sobre+propiedad+literaria+1847
And the code I use is that below:
$file =~ s/\+/\s/; # --> Replace the +
But it seems to only replace the first metacharacter and the result is:
leysobre+propiedad+literaria+1847

switch on the replacement.tr///
operator.Assuming you want to replace
+
by a space:or
