About

What Is an XML File?

XML (eXtensible Markup Language) is a widely used markup language for storing and transporting structured data. An XML file consists of nested elements wrapped in opening and closing tags, along with attributes and text content. It is self-describing, meaning the tags define the structure and meaning of the data.

XML is used in web services (SOAP, REST), configuration files (web.config, pom.xml, AndroidManifest.xml), data feeds (RSS, Atom), vector graphics (SVG), office documents (OOXML), and countless other applications. Our free XML Viewer parses any XML file and displays it as an indented, syntax-highlighted, collapsible tree — without uploading your data.

Use the viewer to inspect API responses, debug config files, validate data exports, or explore complex XML documents. Tag names are shown in blue, attributes in orange, values in green, and text content in dark slate — making it easy to scan even deeply nested structures.

All processing happens in your browser. Your XML data stays on your device at all times — no server, no tracking, no storage.

Syntax Highlighting

Tag names, attribute names, attribute values, text content, and comments are each color-coded for easy reading.

Collapsible Nodes

Click any element to collapse or expand its children. Use Expand All / Collapse All buttons to control the entire tree.

FAQ

Frequently Asked Questions

Common questions about the XML Viewer

Q1. What is XML?
XML (eXtensible Markup Language) is a markup language for encoding structured data. It uses nested elements with opening and closing tags, attributes, and text content. XML is widely used for configuration files, data interchange, web services (SOAP), feeds (RSS/Atom), and document formats (SVG, XHTML).
Q2. Do you upload my XML file?
No. The XML Viewer parses your file entirely in the browser using the built-in DOMParser API. Your data never leaves your device.
Q3. What happens with malformed XML?
If the XML is not well-formed (e.g., unclosed tags, invalid characters), the browser's DOMParser reports the error and the viewer displays the error message so you can fix it.
Q4. Can I collapse and expand nodes?
Yes. Click any element node to toggle its children. You can also use the Expand All and Collapse All buttons in the toolbar above the tree.
Q5. Does it support large XML files?
The viewer works well with files up to several megabytes. Very large files (10 MB+) may be slow because the entire DOM tree is rendered in the browser.
Q6. What about namespaces?
Namespaced elements and attributes are displayed with their full prefixed names (e.g., xs:element, xmlns:soap). The viewer shows the raw tag and attribute names from the parsed DOM.
Q7. Is the XML Viewer free?
Yes. The tool is free to use with no sign-up, no limits, and no ads.
Q8. Can I view SVG files?
Yes. SVG files are valid XML. Simply rename or select the .xml extension, or drag the SVG file onto the viewer to inspect all elements, paths, and attributes.
