new(stream, value=nil, parent=nil, reference=false) public

Create a new entity. Simple entities can be constructed by passing a name, value to the constructor; this creates a generic, plain entity reference. For anything more complicated, you have to pass a Source to the constructor with the entity definition, or use the accessor methods. WARNING: There is no validation of entity state except when the entity is read from a stream. If you start poking around with the accessors, you can easily create a non-conformant Entity. The best thing to do is dump the stupid DTDs and use XMLSchema instead.

e = Entity.new( ‘amp’, ‘&’ )
