XML Tree Viewer

The XML Tree Viewer parses an XML document and presents its elements, attributes, and text content as a navigable tree, so you can understand the document structure without manually counting opening and closing tags. XML nests deeply by nature, and a flat text view makes it hard to see which element is a child of which parent or where a particular attribute belongs. By rendering the parsed node hierarchy, the tool lets you expand and collapse branches, see attribute name and value pairs attached to each element, and read the text nodes contained inside.

Under the hood the viewer runs your input through an XML parser that builds a document object model, then walks that model to produce the tree. Because XML is stricter than HTML, the parser also catches well-formedness errors such as unclosed tags, mismatched element names, or invalid characters, which makes it a quick way to validate a feed or config before processing it elsewhere. Everything runs in the browser, so sensitive XML such as SOAP envelopes or signed assertions stays on your device.

Typical uses include inspecting RSS and Atom feeds, reviewing SVG markup, examining SOAP or XML-RPC responses, understanding Maven pom.xml or Android layout files, and reading sitemaps. It is especially helpful when an integration partner sends a large XML payload and you need to find one specific element among hundreds, or when you need to confirm that namespaces and attributes are placed where a schema expects them. It complements the JSON Tree Viewer for teams that work with both formats and a Mermaid Live Editor when you want to sketch the structure you discover.

A useful tip is to start by collapsing the root element so you can see the document's top-level shape, then drill into the one branch that matters. Watch the attribute list on each element carefully, since XML often carries meaningful data in attributes rather than child elements. If the parser reports an error, the position usually points you straight to the malformed tag, so fix that first before re-pasting the corrected document.
