[oXygen-user] Pretty Print <lb/> in Oxygen

[Alex Jitianu]

Dear all,

In Oxygen version 17.1 you have the possibility to specify "Line break" 
elements [1], that is to say elements for which we have to break the 
line before (or after) serializing them. The entries from this new list 
are a form of simplified XPath expressions that also accept one 
attribute condition (default attribute values are not taken into account):/

- element[@attr]/ - Matches all instances of the specified element that 
include the specified attribute./
- element[not(@attr)]/ - Matches all instances of the specified element 
that do not include the specified attribute./
- element[@attr = "value"]/ - Matches all instances of the specified 
element that include the specified attribute with the given value./
- element[@attr != "value"]/ - Matches all instances of the specified 
element that include the specified attribute and its value is different 
than the one given.

We only accept one attribute condition because we want these expressions 
to run as fast as possible but nevertheless, it should suffice for 
writing expression that take into account the @break attribute. Hope it 
helps!
