Custom NodeValidator refuses mathml elements.

[ktullavik]

I can not get the validator to accept mathml tags. Example:

import 'dart:html';

void main() {
    var validator = new NodeValidatorBuilder();
    validator.allowElement('math');
    validator.allowElement('mtext');
    querySelector('body').setInnerHtml('<math><mtext>Test MathML</mtext></math>', validator: validator);
}

gives console output: Removing disallowed element $ from [object DocumentFragment] Removing disallowed element from math. The allowElement method just calls allowCustomElement internally so that's not the issue. alan-knight commented 7 years ago The underlying problem is that the validator has the tag name in upper case and is checking it against the lower case version it's getting from the element. For built-in elements the tag-name does come back in uppercase. This might be as simple as adding a toUpperCase, but validation is tricky, so I'd want to investigate this more carefully. ktullavik commented 7 years ago Sorry to be that guy, but is there any news on this bug? It's a shame having to setup your own validation or worse, just because of a case bug in dart. © Githubissues. Githubissues is a development platform for aggregating issues. $
