That pretty much was code to tag a text file: 
open(MYINPUTFILE, "<sdnew02.txt");

while (<MYINPUTFILE>){
$_ =~ s/(\s-)$/\<tag\>$1<\/tag\>/g;
$_ =~ s/(:)$/\<tag\>$1<\/tag\>/g;

print $_,"";
}

All I've done is wrap tags around the found object and stick in a global modifier. replace the search regex and tags with whatever you want to tag. It won't quite work around your line breaks, but you can start from there.
