downloading databases introduces unnecessary line breaks

[iztokkosem]

When you download a database from Lexonomy, you get a lot of uneccesary line-breaks before and after the text in XML. This causes huge problems when reimporting the database.
In principle, it is not difficult to get rid of these line-breaks, but it is problematic in examples when line-breaks seem to replace spaces or introduce new spaces when not needed (before punctuation).
