Your code tells the parser to replace the contents on the appropriate
tags with the empty string, so it just displays everything that is
outside the tags. The line breaks (which are, in effect, a character
like any other) are outside the tags, so aren't replaced by your code.

<section lang=en>Foobar</section>(line break)

Parses to:

(line break)

Which displays as a blank line. You need the (line break) to be inside
the section tag, so it doesn't display:

<section lang=en>Foobar(line break)</section>

ie. you need to write:

<section lang=en>Foobar
</section>

Does that make more sense?
