allow creation and deletion of Entity Declaration elements

[jsjuni]

I'm writing a utility to rewrite URIs in some RDF/XML files. This behavior is suprising:

$ irb -r nokogiri
irb(main):001:0> doc = Nokogiri::XML::Document.new
=> #<Nokogiri::XML::Document:0x..fdbbf990a name="document">
irb(main):002:0> ed = Nokogiri::XML::EntityDecl.new('ed', doc)
=> #<Nokogiri::XML::EntityDecl:0x..fdbbf1dea "<ed/>">
irb(main):003:0> ed.content
=> nil
irb(main):004:0> ed.content = 'test'
=> "test"
irb(main):005:0> ed.content
=> nil

That's not what's intended, is it?

The markdown doesn't preserve my line breaks; hope the problem is clear.

I'd like to undefine "content=" for the EntityDecl class. GDOME2 and libxml2 treat entity declarations as read-only elements, and so it's non-trivial for Nokogiri to support modification.

However, it seems like the non-implementation of "content=" isn't the root cause for your request. Correct me if I'm wrong, but what you're trying to do is construct new entity declarations and add them to a new document. Is this correct?

Nokogiri currently has no support for the creation of new entity declarations. If this is what you're asking for, please respond in this ticket.

I need to rewrite some namespaces in OWL ontologies serialized as RDF/XML. They appear in entity declarations, namespace definitions, attributes, and comments. If modifying entity declarations and namespace definitions in place isn't kosher, I'd be happy with the ability to create new ones as long as I can replace (not merely add to) existing ones.

ok, I've changed the name of this issue to "allow creation and deletion of Entity Declaration elements". we'll try to get it into 1.4.1.
