This is my take at it:

use warnings;
use strict;

my @repls = (
    [ qr/pat1/, 'repl1' ],
    [ qr/pat2/, 'repl2' ],
    [ qr/pat3/, 'repl3' ],
);

my $txt = <<'EOF';
This is some example (pat1) text which
will be (pat3) modified according (pat2)
to some replacement (pat2) rules.
EOF

foreach my $r (@repls) {
    $txt =~ s/$r->[0]/$r->[1]/eg;
}

print $txt;
__END__
This is some example (repl1) text which
will be (repl3) modified according (repl2)
to some replacement (repl2) rules.

If you want to capture things and use them, it gets more (too?) complicated:

use warnings;
use strict;

my @repls = (
    [ qr/pat(\d+)/, 'qq{repl$1}' ],
);

my $txt = <<'EOF';
This is some example (pat42) text
EOF

foreach my $r (@repls) {
    $txt =~ s/$r->[0]/$r->[1]/eeg;
}

print $txt;
__END__
This is some example (repl42) text

Note the use of qq{} in single quotes and the double eval in the substitution. The first eval turns $r->[1] into qq{repl$1} and the second one turns that into repl42.
