This method is starting to get a little bit big.

RSD could conceivably be done in its own package, then here we'd just have to do something like
$rsd = new Rsd($url);
if (!$rsd->hasApi('MediaWiki')) {
throw new RsdException( "Unable to find RSD URL in page: $url" );
}
return self::newFromApiEndpoint( $rsd->getApi('MediaWiki')->getApiLink() );But I reckon methods that can be seen whole on one screen are okay. Although I know some people say 20 lines is about the max.
Up to you; I'm happy to rework. (I don't think splitting bits into other methods in this class is much better than this though.)

@samwilson I'm guessing this could go in a bugfix release? |
Are we following semver? If so, I'd say this is a backwards-compatible bug fix that doesn't introduce any new features, so yeah, a patch release is fine. :-) |

@samwilson Looks like this is good to go once rebased! IMO |
Various things, such as duplicate element IDs or repeated attributes, break DOMDocument::loadHTML() and so this turns off the direct reporting (E_ERROR) of these and istead adds them to the RsdException if the RSD URL really can't be determined from the HTML. In most cases, the URL can be found correctly and the errors can be disregarded. A test is added for this as well, although it does *not* test for the case when the RSD URL can't be found and there are libxml errors (because we need to serve up a broken HTML file, and the mediawiki-api-base test system can only interact with MediaWiki via the API, which makes it hard to produce broken HTML that doesn't also have the correct LINK element for the RSD URL). A new TestEnvironment::savePage method is added, for easier creation of test wiki pages. Bug: https://phabricator.wikimedia.org/T163527
