Compare XML with precision and ease. Perfect for data validation, API testing, and debugging.
Highlight XML data differences with different colors, including additions, deletions, and modifications of data items.
Compare XML documents in under a second, then you can see the differences immediately.
Your XML data only exists in memory, and all comparisons are performed in the browser to ensure data security.
Get started with XML comparison in simple steps.
Enter or paste your original and another XML document into the input fields on both sides.
Click the 'Compare' button to compare.
See the difference results with highlighting.
Our tool uses structural comparison to deeply analyze XML documents, going beyond line-by-line text diff to understand the hierarchical nature of XML.
Both XML inputs are parsed using fast-xml-parser into hierarchical tree structures. Elements, attributes, and text nodes are organized into a normalized object representation.
The algorithm recursively traverses both XML trees, comparing elements at each level. It detects added/deleted elements, attribute changes, and text content modifications.
Repeated child elements (like list items) can be matched using three strategies: By Index (positional), LCS (Longest Common Subsequence), or Unordered (ignoring element order).
Differences are mapped back to their source positions in the XML document and rendered with color-coded highlights — green for additions, red for deletions, and yellow for modifications.
XML comparison is essential across many development and data workflows.
Compare XML request/response payloads for SOAP web services, REST APIs with XML responses, or WSDL definitions.
Track changes in XML configuration files such as pom.xml, web.xml, Spring configs, or Android manifest files.
Validate XML data transformations, compare XSLT outputs, or verify data migration results between XML-based systems.
Compare structured documents in formats like DocBook, DITA, or SVG files where XML structure matters.
You can pre-load XML data into the comparison result page by passing query parameters. This is useful for sharing comparisons, CI/CD integrations, or automated testing.
Pass publicly accessible URLs to the base and contrast parameters. The tool will fetch the XML content from these URLs.
Encode your content as a Base64 string and pass it directly. Use base-64.com to encode/decode your data.
