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.
