Compare two XML documents side by side and highlight structural differences. Find added, removed, and changed nodes instantly — free, browser-based, no upload needed.
Ready to compare
Paste two XML documents above and click ComparePaste your original XML in the left panel and the modified XML in the right panel.
Choose whether to ignore attributes, whitespace, or comments before comparing.
Hit the Compare button to see a side-by-side diff with added, removed, and changed nodes highlighted.
XML Diff Tool parses two XML documents and compares them node-by-node, highlighting structural additions, removals, and value changes. Unlike plain text diff, it understands XML structure — so reordered attributes or reformatted whitespace won't create false positives.
No. All comparison is done entirely in your browser using JavaScript. Your XML data never leaves your device.
When enabled, differences caused only by indentation, line breaks, or extra spaces between nodes are ignored. This is useful when comparing formatted vs. minified XML.
Yes, but very large files (1 MB+) may slow down the browser. For best performance, consider comparing specific sections of large documents rather than the entire file.
Green lines are additions in the modified XML, red lines are removals from the original, and yellow lines indicate changed values. Unchanged lines have no highlight.
Yes. By default the tool compares both element content and attributes. You can enable "Ignore attributes" to focus only on element structure and text content.
Yes. XML Diff compares documents positionally, so elements at the same path are compared against each other. Reordered sibling elements will appear as changes.
An XML Diff Tool is a specialized utility that compares two XML documents and identifies structural differences between them. Unlike a plain text diff—which treats XML as raw text and can generate noise from trivial formatting changes—a proper XML diff understands the hierarchical, tree-based nature of XML and compares documents at the node level.
This means it can correctly identify when an element has been added, removed, or had its value changed, even if the surrounding formatting is different. It's an essential tool for developers working with APIs, configuration files, data exports, and any workflow where XML documents evolve over time.

When you submit two XML documents, the tool parses each one into a Document Object Model (DOM) tree. It then traverses both trees simultaneously, comparing nodes at the same positions. For each node, it checks the element name, text content, and (optionally) attributes. Differences are categorized as:
XML remains one of the most widely used data formats in enterprise software, making XML diff a frequently needed operation across many domains:
REST and SOAP APIs often use XML for request and response payloads. When an API changes between versions, comparing the XML responses helps developers understand what data structures have been added, modified, or deprecated. This is especially useful for maintaining backward compatibility.
Many applications—particularly Java-based frameworks like Spring, Maven (pom.xml), and enterprise platforms—store configuration in XML files. Comparing config files across environments (development, staging, production) or before and after a release is a routine DevOps task.
ETL pipelines, EDI systems, and data warehouses frequently exchange XML. When data exports change unexpectedly, an XML diff quickly pinpoints which fields or structures are different, saving hours of manual inspection.
Content publishers and feed aggregators use XML diff to audit feed changes—checking for new entries, modified metadata, or removed items between feed snapshots.
SEO professionals use XML diffs to compare sitemap.xml files before and after site migrations or CMS updates, ensuring no important URLs were accidentally removed.
Our XML Diff Tool presents results in two ways: a side-by-side highlighted view and a structural diff summary. The side-by-side view shows both documents with color-coded lines—green for additions, red for removals, and yellow for modifications. This makes it easy to visually scan for changes.
The structural diff summary presents differences as a flattened path list (e.g., root/config/database/host changed from localhost to db.prod.example.com). This is particularly useful for documenting changes or pasting into pull request descriptions.
A plain text diff compares files line by line without understanding their structure. This works fine for source code, but causes problems with XML because:
An XML-aware diff solves these problems by parsing the structure first and then comparing the semantic content, not the raw text. Our tool supports options like "ignore whitespace" and "ignore comments" to further reduce noise in your comparison results.
To get the most useful results from XML diffing, consider these best practices:
This tool works with any well-formed XML document, including:
