Revered Monks,

For each input string $str I have to test for several possible substitutions, say:

if $str contains tag1 then replace tag1 (in $str) by subst1;

if $str contains tag2 then replace tag2 by subst2;

and so on, and I have 49 such (tag, subst) pairs.

My question, dear and revered and full of wisdom monks, is: could you enlighten me as to a "good" way of programming this?

I mean, do I have any better choice than writing 49 lines like these?:

$str =~ s/tag1/subst1/;
$str =~ s/tag2/subst2/;
$str =~ s/tag3/subst3/;
...
$str =~ s/tag49/subst49/;

At least, is there any syntactic sugar for those 49 lines?

Humbly and in much appraisal,
silentius
