- Optimize your code

Hyphenation can make your justified text prettier by minimization of space between words. Input of this simple program is XML and output is XML with hyphenated every word longer than 5 characters. Hyphenation is done by Open Office hyphenation library. Program is adding the  entity to words which is working in some browsers. Please be aware it's not optimized code, but as far as it's used relatively rarely (on insert or update not on select) it is not worth optimization in most of implementations.
