XML Compare
- Browser-based
- No signup
Paste XML on the left and right to compare element trees. Attribute order and insignificant whitespace are ignored; child order matters. Comments and declarations are skipped. Differences are listed as added, removed, or changed paths. Comparison runs entirely in your browser.
100% Client-Side
Your data never leaves your computer.
How to use this tool
1. Paste source text, code, or data into the XML Compare input panel. 2. Choose transform or validation options shown for XML Compare. 3. Run XML Compare or read automatic output. 4. Review errors or diff output carefully. 5. Copy the transformed result. Processing runs in your browser; inputs are not uploaded to our server.
Worked example
Example: paste a small sample input into XML Compare, run the transform or validation, and compare the output with the before text—fix any syntax errors reported before copying.
How it works
Paste XML on the left and right. Both sides are parsed into element trees, then compared structurally. Attribute order and insignificant whitespace are ignored; child element order matters. Comments and declarations are skipped. Differences are listed as added, removed, or changed paths. Comparison runs entirely in your browser.
Limitations
Results are based on the inputs you provide and may not cover every edge case. This tool is for general use and is not professional advice.
Privacy and file handling
Your data is processed in your browser and is not uploaded to our server.
Frequently asked questions
Does attribute order matter?
No. Attributes are compared by name. Insignificant whitespace between tags is also ignored. Child element order matters.
Are comments compared?
No. Comments, declarations, and DOCTYPE nodes are skipped so you can focus on element structure, attributes, and text.
Is my XML stored?
No. Comparison runs locally in your browser and input is not stored.
