Hello Monks,

I believe my problem is a general problem. I did a search, but found no answers.

Description:

There is a HTML file to be processed. I want to substitute a pattern with another one. There are many patterns to be processed, but I do not know how many. I came up a structure so that I can easily add a new pattern.

The structure looks like: 

$file= '<A NAME="TOC124" HREF="cvs.html#SEC124">A.8 commit--Check file
+s into the repository</A>';

 $c->{Anchor}{from}='<A NAME="(.*?)" HREF=".*?\#(.*?)">(.*?)</A>';
 $c->{Anchor}{to}='$3 |$2| *$1*';

foreach $item (keys %$c) {
    $from=$c->{$item}{from};
    $to=$c->{$item}{to};
    $file=~s/$from/$to/sg;
}

print "$file\n";

There is hash reference $c where I plan to add more pattern as long as necessary. The main body foreach process each of the patterns.

The expected result is:
A.8 commit--Check files into the repository |SEC124| *TOC124*

The result of my program is:
$3 |$2| *$1*

Here the problem is that $1,$2 and $3 is not evaluated. This is reasonable as I coded like this. My question is how can I make them evaluated ?

Thanks for any of your suggestions!
