You are reading the file a line at a time. So when you process the TITLE line, the data in $_ only contains the line that begins with TITLE. So that is all that ends up in $title. The rest of the TITLE data is processed on the next iteration of the loop (and, probably ends up as the first element in @se).

There are a couple of ways to solve this:

1. Write a more complex parser. Keep a note of the _previous_ line's tag and if the current line starts with whitespace then append this data to the end of the previous tag.
2. Read all the whole file into memory and parse it using more complex regular expressions.
