XML Compare – Element Node & Attribute Diff Checker
Compare two XML documents hierarchically. Detect added element tags, removed attributes, text node modifications, namespace URIs, and exact XPath pointers.
XML Compare Features
DOM element tree analysis, XPath pointers, attribute checks, and privacy
📜 DOM Node Traversal
Evaluates element tags, nested child nodes, and text content hierarchically.
📍 XPath Pointer Location
Traces exact element paths (e.g. `/workspace/modules/module[2]`) across DOM nodes.
🏷️ Attribute & Namespace Audit
Identifies attribute value changes and namespace URI mismatches.
🔒 100% Client-Side Privacy
All XML comparison happens in browser RAM using DOMParser. Zero files are uploaded to servers.
Review changes between two XML documents
When an XML export or configuration changes, the important differences may be buried among many repeated tags. Compare the original and updated documents to find added or removed elements and changed text or attributes, then review the surrounding structure before using the new version.
Load the original XML and the modified XML in the two input areas.
Run the comparison and inspect added nodes, removed nodes, and changed text or attributes.
Follow each reported difference back to its parent element. Confirm that repeated records and important identifiers still appear as expected.
Check structure as well as values
An XML change can affect more than the text inside a tag: moving a child element, changing an attribute, or removing a repeated node can alter how another system reads the document. Review the parent and sibling elements around each difference rather than judging a change from a single value.
A diff shows what changed between the two supplied documents; it does not prove that the new XML is valid or compatible with the receiving system. Validate the updated document and test it against the expected schema or workflow when correctness matters.
Frequently Asked Questions
How does XML tree comparison evaluate attributes and elements?
The XML Compare tool parses both XML files into DOM element trees, evaluating tag names, attribute key-value pairs, namespace URIs, and text node content hierarchically.
Is my XML document safe during comparison?
Yes, 100% private. All DOM parsing, XPath generation, element diffing, and report downloads execute locally in your web browser RAM.
Does the tool check for XML syntax errors before comparison?
Yes! The DOMParser automatically validates XML syntax and highlights parser errors if unclosed tags or invalid entities are present.
