About The XML Diff

XML Diff compares two XML text inputs and reports line-level additions, removals, and edits. It is useful for reviewing feed changes, configuration edits, exported XML, and small document updates.

The comparison runs locally in your browser. This tool performs a text diff, so indentation, line breaks, and formatting changes can appear in the result even when the XML structure is logically similar.

How to Compare XML Online

1. Paste the baseline XML into XML A.
2. Paste the changed XML into XML B.
3. Click Compare XML.
4. Review removed and added lines in the result.
5. Copy the output when you need a plain-text diff for notes or review.

Choosing Options Correctly

Input order:
Use XML A for the original document and XML B for the new document. Reversing them changes which lines are shown as removed or added.

Common Use Cases

• Checking changes in XML configuration files.
• Comparing feed exports from two systems.
• Reviewing small SOAP or XML API payload differences.
• Preparing a readable diff for a support ticket or code review.

Quick FAQ

Does this parse XML structure?
It can compare XML-aware output when parsing succeeds, but malformed XML may fall back to text-like comparison or fail.

Why do whitespace changes show up?
Whitespace can be meaningful in XML text nodes, and formatting differences may still appear depending on comparison mode.

Can I paste private XML here?
Avoid secrets, customer records, and private configuration unless browser-based tools are allowed in your workflow.

Does it understand XML schemas?
No. It compares documents; it does not validate XSD rules or semantic equivalence.
