XML Diff Tool: Compare XML Files Semantically Online
Compare two XML documents with this semantic XML diff tool. Choose whether to ignore whitespace, comments, attribute order, or element order, then review changes labeled by XPath. If you need to compare the text view, a line-level diff is available as a fallback. Paste both versions, run the comparison, and step through the differences.
XML Diff is a browser-based XML diff tool for comparing two XML documents semantically. Paste or drop both versions into the tool, run the comparison, and review the differences it finds. Changes are labeled by XPath, with a line-level diff available as a fallback for the text view.
You can choose to ignore whitespace, comments, attribute order, and element order during the comparison. These options let you focus on the kinds of differences that matter for your review. Step through the results to inspect the reported changes and their XPath locations.
XML represents structured data with elements and attributes, while a text view presents the document as lines of text. Comparing XML semantically can help distinguish structural changes from differences such as whitespace or ordering when you choose to ignore them. A line-level diff provides another way to inspect the text view.
The comparison runs entirely in your browser. Your XML input is processed on your device and is not uploaded, stored, or sent to a server. Once the page has loaded, the tool works offline, and it is free to use.
This XML diff tool can help developers and DevOps engineers review file changes, check refactors, or investigate differences between XML versions. Whether you are making a quick check or reviewing a change before a commit, XPath-labeled results help you find where the documents differ.
Step 1: Paste or drop the two XML versions into the tool. Use the documents you want to compare, such as the before-and-after versions of a file.
Step 2: Choose which differences to ignore. The comparison can ignore whitespace, comments, attribute order, and element order.
Step 3: Run the XML diff. The tool compares the documents semantically using your selected settings.
Step 4: Review the changes labeled by XPath. These labels help you locate differences in the XML structure.
Step 5: Step through the differences and use the line-level diff as a fallback when comparing the text view.
Use case: Review XML changes before committing a file. A semantic comparison can help you focus on meaningful differences rather than ignored whitespace or ordering changes.
Use case: Check whether an XML refactor was a no-op. Compare the original and refactored documents, then inspect any differences the tool reports.
Use case: Find a small change in two XML files that look identical at a glance. XPath labels help point you to the location of each reported change.
Use case: Compare XML configuration files before and after an update. Ignore comments or whitespace when those differences are not relevant to your review.
Use case: Check whether reordered XML elements or attributes are the only differences between two versions. Use the order options to decide whether those changes should be ignored.
Use case: Review changes in an XML text view when you need a line-based comparison. Use the line-level diff fallback to inspect text differences.
