 perl -e '$x=qw(&apm;gt;lt;amp;);$x=~s/;(.)/;&$1/g;print $x,"\n";'

Thanks, but this is just a solution for this particular example; I need a general solution for any codes.

You need to implement a lookup table that contains a list of all possible, or otherwise a subset, of HTML character codes.

Therefore, each time your program encounters

code;

instead of

&code;

, it will need to add an ampersand at the start.
