Does embperl have it's own $1, $2, etc. like the ones captured when using parenthesis
in a matching expression? If not, does embperl do something to these
variables produced by the parenthesis (like discard or ignore them)? To illustrate
what I'm talking about here's some embperl code:
[- $text = 'This: http://www.blah.com is a url'; -]
[$ if $text =~ /(.*\s)(http\:\/\/\S+)(\s.*)/i $]
[+ $1 +]<a href="[+ $2 +]">[+ $2 +]</a>[+ $3 +]
[$ else $]
[+ $text +]
[$ endif $]
Which, I don't know why, produces the output:
<a href=""></a>
The equivelant (I think) non-embedded perl code:
$text = 'This: http://www.blah.com is a url';
if ($text =~ /(.*\s)(http\:\/\/\S+)(\s.*)/i )
{
print "$1<a href=\"$2\">$2<\/a>$3\n";
}
else
{
print "$text\n";
}
outputs what I am trying to achieve w/ the embperl code:
This: <a href="http://www.blah.com">http://www.blah.com</a> is a url
so why doesn't the embperl version work?
