Bug 153378 – An XMLDocument interface should be exposed on the global Window object

• Component: DOM
• Status: RESOLVED FIXED

[Chris Dumez]

An XMLDocument interface needs to be exposed on the global Window object, as per:
https://dom.spec.whatwg.org/#xmldocument

Currently, WebKit aliases XMLDocument to Document which causes some W3C tests to fail.

Chrome and Firefox already match the specification here.

DOM spec now defines XMLDocument: https://dom.spec.whatwg.org/#xmldocument

I don't quite understand the purpose of it though...

It seems part of the reason why XMLDocument exists is to expose load() to XMLDocuments (but not HTML ones):
https://html.spec.whatwg.org/#dom-xmldocument-load

We don't seem to implement Document.load() at the moment.

That said, other browsers have XMLDocument, it is in the HTML / DOM specs, it is covered by standards compliance tests, and it is not much effort or code to support it.

So wordy, and yet many these properties like TreatNullAs and Default aren’t even used by ObjC and GObject bindings.

Indentation seems random.

> +    XMLDocument(Frame* frame, const URL& url, unsigned documentClasses)
> +        : Document(frame, url, documentClasses)

Seems like this constructor should either do:

    : Document(frame, url, XMLDocumentClass | documentClasses)

or:

    ASSERT(documentClasses & XMLDocumentClass);
