How XML Diff Checker works
Compare parsed XML trees, ignoring attribute order and whitespace-only text between elements.
Processing uses bundled libraries in this browser. The result table shows the supported checks; it does not query another service.
How to compare XML
Start with the supported input, then check the generated result.
Enter the source details
Use Original XML, Updated XML. The form starts with an example you can replace.

When to use XML Diff Checker
These workflows use the formats and behavior supported by this implementation.
Find a changed attribute
Attribute order is ignored, but a changed attribute value is reported with a path and before/after text.
Compare record text
Changes in meaningful text and child order remain significant. Use the path table to locate the affected part of the documents.
Ignore indentation-only differences
Whitespace-only text between elements is ignored. Namespace prefixes are still compared as written, so this is not full XML semantic equivalence.
What the check result contains
Keep the output format and conversion policy in view.
Changed XML paths and values. Compare parsed XML trees, ignoring attribute order and whitespace-only text between elements.
Compare the result with the original before replacing a source file. Conversion limits are listed below.
Supported input and limits
Check these conditions before relying on the result.
Child order and meaningful text remain significant. Namespace prefixes are compared as written. Up to 1,000 displayed differences. DTDs and entity declarations are rejected.
Input and results are not stored after leaving or reloading. Keep the original and download any output you need.
