SSS

Do you store my XML?

No. All processing happens in your browser. Your data never leaves your device.

What XPath expressions are supported?

We use the browser's native XPath engine, supporting the full XPath 1.0 spec: //element, /path/to/node, [@attribute='value'], text(), count(), position(), and all axes (child, descendant, parent, ancestor, etc.).

Does it support XSD validation?

Not yet. We currently check well-formedness only. XSD/DTD schema validation is planned for a future update.

Can I format large XML files?

Yes, but very large files (over 1MB) may cause slower performance. For optimal results, keep files under 10MB.

How does the diff comparison work?

Paste your original XML in the input and a modified version in the diff tab. Click Compare to see a color-coded unified diff with additions (green), removals (red), and summary statistics.

Can I search within the tree view?

Yes. Use the search box above the tree view to filter nodes by tag name, attribute name/value, or text content. Matching nodes are highlighted and parent nodes auto-expand.

What transform operations are available?

Remove Comments strips all XML comments, Remove Empty removes elements with no content, Sort Attributes alphabetizes attributes, and you can add or remove the XML declaration.

Is my data secure?

Absolutely. All XML processing happens locally in your browser using JavaScript. No data is transmitted to any server.
