ereg - template HTML

Hi, I have an array eg $a[test] = "value1"; $a[test1] = "value2"; etc I would like to be able to take the names in the array and find where those names are used in an html file and then substitute the value (ie value1 and value2) into the element identified with {{ }} around it - a std template type of approach. <input type=text name=test value='{{test}}'> <input type=text name=test1 value='{{test1}}'> etc becomes: <input type=text name=test value='value1'> <input type=text name=test1 value='value2'> in Perl I could do it something like (where $HTML is the array and template points to the template I want to fill in): open (FILE, "<$template") or die "Couldn't open $template: $!\n"; while (<FILE>) { s/{{(.*?)}}/$HTML->{$1}/g; $content .= $_; } close FILE; return $content; I guess what I am looking for is the appropriate ereg(?) statement to achieve the above - hope someone can help ? cheers Jim Carey
