What is XML Viewer?
XML Viewer is an interactive web tool that transforms flat or formatted XML markup into a dynamic, collapsible visual tree hierarchy. Navigating multi-megabyte XML files with dozens of nested child elements, attribute maps, and namespaces in standard text editors can be overwhelming. The XML Viewer parses the DOM document model and presents an interactive node tree, allowing developers to collapse or expand branches, examine attribute maps inline, and inspect node values effortlessly.
How to use XML Viewer
Paste your XML payload into the input panel. The viewer automatically builds an interactive DOM tree representation on the right. Click any element arrow to collapse or expand its child nodes. Attributes associated with XML elements are rendered inline with key-value syntax highlights. Use the 'Expand All' and 'Collapse All' buttons to change the view state globally, and copy individual node contents or complete element paths as needed.

Technical details & standards
The XML Viewer leverages recursive DOM tree construction and virtual rendering techniques to ensure fluid performance even when displaying large, deeply nested XML documents. All processing is executed entirely in your local browser JavaScript engine. No external network data calls are made, ensuring complete safety for enterprise documents and confidential data.
Frequently asked questions
Can XML Viewer inspect large XML files over 20MB?
Yes. The client-side parser handles multi-megabyte files smoothly, limited only by your computer's available memory.
How are XML attributes displayed in the viewer?
Attributes appear inline right next to the opening tag node (e.g., <User id='101' status='active'>), visually highlighted for easy readability.
Is my data safe?
All processing happens entirely in your browser. Your data never leaves your device and is never sent to or stored on a server.
Does it work offline?
Yes. Once the page has loaded, most tools keep working without an internet connection.
