What Is an XML Tree Viewer?
An XML Tree Viewer parses raw XML text and renders it as an interactive, hierarchical node tree — much like a file explorer, but for markup data. Every element becomes a collapsible branch, attributes are shown inline, and text content is clearly labelled. This makes it far easier to understand deeply nested XML documents than staring at raw angle brackets.
This tool processes your XML entirely in your browser using the built-in DOMParser API. Nothing is sent to any server — your data stays private.
Common XML Use Cases
- API responses — many SOAP and legacy REST APIs still return XML; the tree view makes debugging much faster.
- RSS / Atom feeds — inspect channel metadata, item titles, publication dates, and enclosures at a glance.
- Configuration files — Maven
pom.xml, AndroidAndroidManifest.xml, Spring contexts, and MSBuild files are easier to audit as a tree. - SVG files — SVG is XML; viewing the element hierarchy helps understand how shapes, groups, and transforms are nested.
- Data exchange formats — XBRL financial reports, GPX GPS tracks, COLLADA 3D models, and Office Open XML are all XML under the hood.
Frequently Asked Questions
XML is strict — every opening tag must have a matching closing tag, attribute values must be quoted, and special characters like
&, <, and > must be escaped as entities. The error message shown will indicate the line and column of the problem. Common issues include missing closing tags, unescaped ampersands in URLs, and incorrect nesting.When you click a node in the tree, the inspector shows its path — for example
/bookstore/book[2]/title. This is an XPath-style notation that describes exactly where in the document hierarchy the node lives. You can use these paths in XSLT stylesheets, XPath queries, or libraries like lxml, libxml2, and Java's JAXP to programmatically select that node.An element is a named tag that can contain children, text, or other elements — e.g.
<title>Hello</title>. An attribute is a name-value pair inside an opening tag that describes a property of that element — e.g. category="fiction". In the tree view, elements appear as collapsible rows in blue, while attributes are shown inline in amber/orange.The Format button re-serialises the parsed XML back to a pretty-printed string with consistent 2-space indentation. This is useful for minified or single-line XML that's hard to read. Note that formatting normalises whitespace-only text nodes, so the output may differ slightly from the original if it contained mixed whitespace.
If your HTML is valid XHTML (well-formed XML), yes — it will parse and display correctly. Standard HTML5, however, is not strict XML and may contain self-closing tags, optional end tags, or unquoted attributes that will cause parse errors. For HTML inspection, browser DevTools (F12) are a better fit.
