Class: REXML::AttlistDecl
- Includes:
- Enumerable
- Defined in:
- lib/rexml/attlistdecl.rb
Overview
This class needs:
-
Documentation
-
Work! Not all types of attlists are intelligently parsed, so we just
spew back out what we get in. This works, but it would be better if we formatted the output ourselves.
AttlistDecls provide just enough support to allow namespace declarations. If you need some sort of generalized support, or have an interesting idea about how to map the hideous, terrible design of DTD AttlistDecls onto an intuitive Ruby interface, let me know. I’m desperate for anything to make DTDs more palateable.

-
#[](key) ⇒ Object
Access the attlist attribute/value pairs.

Iterate over the key/value pairs: attlist_decl.each { |attribute_name, attribute_value| … }.
-
#include?(key) ⇒ Boolean
Whether an attlist declaration includes the given attribute definition if attlist_decl.include? “xmlns:foobar”.
-
#initialize(source) ⇒ AttlistDecl
constructor
Create an AttlistDecl, pulling the information from a Source.
- #node_type ⇒ Object

#write(out, indent = -1) ⇒ Object
Write out exactly what we got in.

Constructor Details
#initialize(source) ⇒ AttlistDecl
Create an AttlistDecl, pulling the information from a Source. Notice that this isn’t very convenient; to create an AttlistDecl, you basically have to format it yourself, and then have the initializer parse it. Sorry, but for the forseeable future, DTD support in REXML is pretty weak on convenience. Have I mentioned how much I hate DTDs?
