Hi,
I have a problem when I use regular expression.
The sample code:
[- $_ = "One Two Three" -]
[$ if(/(\S+) (\S+) (\S+)/) $]
The words are: [+$1+], [+$2+], [+$3+]
[$ endif $]
The result should be "The words are: One, Two, Three," But I got the
result "The words are: One, Two,."
After trying, I found that I could just get the match variables $1 and
$2, and the match veriables $3, $4 etc, could not be used in embperl.
There is no problem about this in pure perl code such as
$_ = "One Two Three";
if(/(\S+) (\S+) (\S+)/) {
printf "The words are: $1, $2, $3";
}
