Mismatched Option Values (intentionally corrupt HTML)
Intentionally corrupt. A select has two options with the same value under different labels, a radio group repeats a value, and one option's value contradicts its wording outright. A form that reads labels and a form that reads values disagree about what was chosen.

What is a .html file?
HTML (HyperText Markup Language) is the structural markup language of the web, using nested tags to define document content, semantics, and links. It is typically paired with CSS for presentation and JavaScript for behavior. It is the foundational format rendered by browsers.
How to use this file
Use an example HTML file to test parsers, DOM construction, sanitization of untrusted markup, and rendering or scraping pipelines.
How to use this file for testing
“Mismatched Option Values (intentionally corrupt HTML)” is a deterministic Novus Examples fixture for Form testing, Form parsing, Autofill testing, HTML parsing. HTML and PDF form files for testing scrapers, autofill, validators, and PDF form fillers across real-life use cases.
Documented properties for this file: 5 fields. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
This form is fictional SAMPLE content for tooling tests (autofill, scrapers, PDF fillers). It is not an official government, bank, or clinic form. Open the HTML offline or fill the PDF in any viewer; the demo submit path never stores data.
Embed this form
It's a single self-contained HTML file (inlined CSS, native validation, no external requests). Download it, host it on your own site, and drop it into any page with an iframe.
