Why is this not working?
$data = "What is the STATUS of your mind right now?";
$data =~ tr/ +/ /;
$data =~ s/ +/ /; instead.
tr is the translation operator. An important thing to note about this is that regex modifiers do not apply in a translation statement (excepting
- which still indicates a range). So when you use
tr/ +/ / you're saying "Take every instance of the characters space and
+ and translate them to a space". In other words, the
tr thinks of the space and
+ as individual characters, not a regular expression.
$data = "What is the STA++TUS of your mind right now?"; $data =~ tr/ +/ /; print $data; #Prints "What is the STA TUS of your mind right now?"
s does what you're looking for, by saying "match any number of consecutive spaces (at least one instance) and substitute them with a single space". You may also want to use something like
s/ +/ /g; if there's more than one place you want the substitution to occur (
g meaning to apply globally).
