Re^2: Regexp question

One last quick question. Is this valid for checking whether the match occurred, and would $1 be initialized to the matched text in this code?

if ( $html =~ m/id="$element" name="challenge" value="(.*?)"/ ) {
            $post{$element} = $1;
            }

I believe so, but you can easily prove it for yourself with a trivial testcase.	[reply]

Yes, that'll work. As will `$post{$element} = $1 if $html =~ m/id="$element" name="challenge" value="(.?)"/;` [download] Unless you expect* `$element` to contain metacharacters, you should use `m/id="\Q$element\E" name="challenge" value="(.*?)"/;` [download] to escape any metacharacters in `$html`.
