Free XML Tree Viewer Online

XML Input

Tree Output

If you've ever opened a large XML file and stared at a wall of angle brackets trying to figure out where one element ends and another begins, you know the pain. The XML specification is flexible enough to describe almost anything, but that flexibility means documents can get deeply nested fast. This tree viewer takes your raw XML, parses it with your browser's built-in DOMParser API, and renders a collapsible tree that shows every element, attribute, and text node at a glance. No more squinting at indentation or counting closing tags.

How to Use the XML Tree Viewer

Paste Your XML

Copy any XML document and paste it into the input. The tree view renders automatically for both small and large XML documents.

Explore the Tree

Click on any node to expand or collapse it. The tree shows elements, attributes, and text nodes in a clear hierarchical structure.

Navigate and Inspect

Use the tree to understand the XML structure, locate specific elements, or verify the document hierarchy before processing it programmatically.

Example XML Structure

Example: Product catalog XML

XML input:

<catalog>
  <product id="1">
    <name>Widget Pro</name>
    <price currency="USD">29.99</price>
    <stock>150</stock>
  </product>
</catalog>

Tree structure rendered:

catalog
└─ product [id="1"]
   ├─ name: "Widget Pro"
   ├─ price [currency="USD"]: "29.99"
   └─ stock: "150"

Frequently Asked Questions

Is my XML data sent to a server?

No. Everything happens locally in your browser using the native DOMParser API. Your XML never leaves your machine — you can verify this in your browser's Network tab.

What happens if my XML has errors?

The browser's parser will flag the issue and the tool will show an error message with details about what went wrong. Unlike JSON, XML is strict about well-formedness — every opening tag needs a closing tag, attributes must be quoted, and special characters need escaping. The W3C well-formedness rules cover the full list.

How large of an XML file can I view?

There's no hard limit from the tool itself — it depends on your browser's available memory. Files up to 10-15 MB typically work fine in Chrome and Firefox. For very large documents, consider using a desktop tool like XMLStarlet from the command line.

Can I use this to view SOAP or WSDL responses?

Absolutely. SOAP envelopes and WSDL definitions are just XML documents, so they render perfectly as a tree. It's often the fastest way to understand the structure of an unfamiliar web service response without firing up a full IDE.
