Hybrid bookmarklet to run after validating markup to check WCAG 4.1.1 Parsing conformance

Nu Html Checker Hybrid Parsing Bookmarklet

Hybrid bookmarklet to run after validating markup using the Nu Html Checker to check for WCAG 4.1.1 Parsing conformance.

How to use

• Visit Nu Html Checker Bookmarklet page and drag it to your bookmarks. Or, manually create your own by using this JavaScript as the URL.
• Run the Check serialized DOM of current page bookmarklet to validate the page. Or, use the "Send selected DOM" button in the ARC Toolkit to send the DOM to the validator.
• Then run the Nu Html Checker Hybrid Parsing bookmarklet by clicking on it in your bookmarks to see the results.
• Issues that are not pure WCAG 4.1.1 Parsing issues are removed.
• Issues that may not be hard WCAG 4.1.1 Parsing issues but should be considered for fixing will be identified as "Not a WCAG 4.1.1 Parsing failure / Validation Issue: ..."

Background

There are currently two schools of thought with regards to testing for conformance to WCAG 4.1.1 Parsing after running the Nu Html Checker.

• Check for WCAG 2.0 parsing compliance bookmarklet - Steve Faulkner [validation type issues remain e.g. content model]
• WCAG Syntax Only Bookmarklet - Christophe Strobbe [removes all validation type issues leaving pure syntax-style issues]

I've combined these two approaches so that only true WCAG 4.1.1 failures are presented, but issues that are not hard failures and are worth consideration of fixing are still present in the results and clearly marked as such.
