XML DOM practice

This fixed fictional example parses two items, reads a namespaced field, appends an item, and serializes the document. It sends no data to a service. A malformed-input check runs alongside it.

Select Run example. Expected: 2 items before, Desk & Lamp, 3 items after, malformed input rejected.

Inspect the code

Serialization can change XML spelling while preserving meaning. This exercise uses a detached XML document and displays output as text.
