<work_notes>
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod 
tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim 
veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea

velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint

</work_notes>

is there a way i can force a </br> after a certain number of words in 
each line? in a xslt? (Netbeans)

A second question, perhaps more complicated:

Has anyone any recommendations on how i might achieve the following:

something like:

1)check directory for changed xml files

2) if changed/new xml

3) apply xslt

Many thanks, and best regards from London,
