Parsing

Level AFully Automatable

WCAG Requirement

In content using markup languages, elements have complete start and end tags, are nested correctly, don't contain duplicate attributes, and IDs are unique. (Note: obsoleted in WCAG 2.2 but still in 2.1)

Experience Builder Notes

EB's Jimu framework generally handles this, but custom HTML in Embed widgets may have parsing errors.

Sufficient Techniques

  • ✓Validate HTML markup
  • ✓Ensure unique IDs on all elements

Common Failures in EB Apps

  • ✗Duplicate IDs from repeated widgets
  • ✗Invalid HTML in Embed widget
