WebKit Bugzilla
Right now, createContextualFragment throws NOT_SUPPORTED_ERR and insertAdjacentHTML doesn't throw any errors. We should throw SYNTAX_ERR to be consistent with the spec and Firefox. http://html5.org/specs/dom-parsing.html#parsing http://www.whatwg.org/specs/web-apps/current-work/multipage/the-xhtml-syntax.html#xml-fragment-parsing-algorithm

Will do once I get a review.

Does it raise exceptions? IE doesn't throw exceptions for all cases tested here. I'm making insertAdjacentHTML throw for consistency with other APIs. (e.g. it's surprising if innerHTML throws and insertAdjacentHTML doesn't throw for the same markup). Given that insertAdjacentHTML isn't a particularly popular API and that this only happens in XHTML document, I don't expect there to be any compat. issues. > > Source/WebCore/editing/markup.cpp:669 > > + ExceptionCode ignoredEC; > > + RefPtr<DocumentFragment> fragment = createContextualFragment(markup, fakeBody.get(), scriptingPermission, ignoredEC); > > Seems worth commenting why it's ignored. createFragmentFromMarkup is only used for copy & paste purposes (and moving paragraphs). I'm intending to rename this function to make it clear why ignoring the exception makes sense. But do you have a suggestion on what kind of comment we should add? > > Source/WebKit/qt/Api/qwebelement.cpp:1063 > > + RefPtr<DocumentFragment> fragment = createContextualFragment(markup, toHTMLElement(m_element), AllowScriptingContent, exception); > > > > if (m_element->hasChildNodes()) > > m_element->insertBefore(fragment, m_element->firstChild(), exception); > > What happens if this raises an exception? Looks like a crash due to null fragment to me. Yeah, but I'm not changing the behavior here. We have always returned null fragments when XML parser returned null. Folks from the Qt port needs to address this issue.
> insertAdjacentHTML isn't a particularly popular API and that this only happens in XHTML document It does seem that the general rule of sticking to majority behavior is weaker here, and and consistency arguments feel a bit stronger than usual.

Adding an exception is always scary. Can you document here what other browsers do, and why we're making this change? Is there a sepc which says we should throw here?

Can you document here what other browsers do, and why we're making this change? Is there a sepc which says we should throw here? Yes, see my original bug report: Right now, createContextualFragment throws NOT_SUPPORTED_ERR and insertAdjacentHTML doesn't throw any errors. We should throw SYNTAX_ERR to be consistent with the spec and Firefox. http://html5.org/specs/dom-parsing.html#parsing http://www.whatwg.org/specs/web-apps/current-work/multipage/the-xhtml-syntax.html#xml-fragment-parsing-algorithm I can include that in the change log if you want.

Okay. It'll be a bit invasive but no problem.
