Add Errors to XML

Add Errors to XML for testing and simulation. Inject typos, corrupt tags, and strip attributes live in the browser with control over intensity and type.

    • Drop attributes: Randomly removes attributes from opening tags.
    • Maximize output: Expands the output preview box.

  • Copy or export the result using the buttons.
  • Use Clear All to reset everything.

What Add Errors to XML can do:

Add Errors to XML is perfect for stress-testing XML parsers, debugging error handling logic, or generating broken markup for demos and training. You control what kinds of corruption to apply whether that’s light character swaps, broken closing tags, or attribute drops. Choose between light or heavy disruption modes, and see changes update in real time. Great for developers and QA engineers working on robust XML tools.

Example:

Original:

<user id="123"><name>Alice</name></user>

With errors:

<user><name>Ali ec</nam</user>

Common Use Cases:

Use Add Errors to XML when you want to intentionally break XML for validation testing, resilience checks, or software training. It’s useful for mocking invalid data, simulating corrupted files, or verifying your application’s error recovery flow.

Useful Tools & Suggestions:

If you’re injecting errors for testing, try Validate XML right after to see what breaks and how. And when you’re ready to reverse the chaos, Flatten an XML can help simplify things before a cleanup.
