About the XML diff tool

Two documents render side by side with differences highlighted in place. The defaultDiff view is a line-level diff of both documents pretty-printed the same way, so you can see exactly which lines changed. Switch to Tree for a structural comparison that walks the element tree instead — attributes, text, and child elements are marked added, removed, or changed, with a dashed marker on any collapsed branch that contains a change.

The two views are complementary. A re-indentation-only change shows up in the line view but not the tree view, while a change that touches an attribute value is called out precisely by the tree view. Hover any diff line to copy it, or use the per-node copy menu in the tree view.

FAQ

Is my XML sent anywhere?

No. Both documents are parsed and compared entirely in your browser — nothing leaves this tab.

Does the tree view respect namespaces?

Yes — element and attribute names keep their prefixes, so namespaced documents diff correctly.

Does child order matter?

The line view is order-sensitive. The tree view groups repeated sibling tags by name, so reordering siblings won't flag as a change there.
