God, I hate DTDs. I really do. Why this idiot standard still plagues us is beyond me.

Public Class methods

new(stream, value=nil, parent=nil)

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 definiton, 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.

matches?(string)

Evaluates whether the given string matchs an entity definition, returning true if so, and false otherwise.

parse_source(source)

Public Instance methods

write(out, indent=-1)

Write out a fully formed, correct entity definition (assuming the Entity object itself is valid.

to_s()

Returns this entity as a string. See write().

value()

Returns the value of this entity. At the moment, only internal entities are processed. If the value contains internal references (IE, %blah;), those are replaced with their values. IE, if the doctype contains:

     <!ENTITY % foo "bar">
     <!ENTITY yada "nanoo %foo; nanoo>

then:

     doctype.entity('yada').value   #-> "nanoo bar nanoo"
