Compare two XML files line by line
Paste or open two XML documents to find changes in tags, attributes, values, namespaces, and formatting. Use split view for side-by-side XML comparison or unified view for a compact patch-style result.
This is a source-text comparison rather than a semantic XML parser. Ignore whitespace or case when appropriate, hide unchanged context, and select a changed row to edit or merge it in either direction. Undo, redo, and local unified-diff export are available.
Try an XML release change
Open the filled XML example to review an attribute change, a repeated element, and a status update.
DiffPeek does not resolve namespaces semantically, canonicalize XML, expand external entities, validate against XSD/DTD, or treat reordered attributes as equivalent. The tool compares the source text and does not fetch referenced resources.
Compare markup with HTML Diff, review general configuration files with File Compare, or inspect a complete project with the Folder Diff Checker.
