XML Viewer – Online Tool with Syntax Highlighting & Tree View

Welcome to the most powerful online XML viewer. Whether you are a developer debugging API responses, a data analyst inspecting XML feeds, or a student learning XML structure, our tool provides crystal‑clear visualization with syntax highlighting, collapsible tree navigation, and instant validation.

Key Features

• Syntax Highlighting – Elements, attributes, values, comments, and processing instructions each have distinct colors for effortless scanning.
• Interactive Tree View – Collapse and expand nodes to focus on specific sections. Click on any node to see its full path.
• Search & XPath – Find text within the document or run XPath 1.0 expressions to locate matching nodes instantly.
• Validation – Real‑time well‑formedness check with line‑by‑line error reporting.
• Multiple Input Methods – Upload a .xml file, paste raw XML, or fetch from any public URL.
• Export Options – Download formatted XML, copy to clipboard, or print.

Example XML Display

<?xml version="1.0" encoding="UTF-8"?>
<bookstore>
  <book category="fiction">
    <title lang="en">The Hobbit</title>
    <author>J.R.R. Tolkien</author>
    <price>12.99</price>
  </book>
  <book category="nonfiction">
    <title lang="en">A Brief History of Time</title>
    <author>Stephen Hawking</author>
    <price>18.99</price>
  </book>
</bookstore>

In our viewer, the above XML appears with color‑coded tags, indented structure, and clickable tree arrows. You can collapse the second book node, search for "Hawking", or run an XPath like //book[@category='fiction']/title to highlight only fiction titles.

Why Use Our XML Viewer?

Many developers struggle with unformatted XML logs or minified API responses. Our viewer instantly transforms any XML into a human‑friendly layout. The combination of tree view and syntax highlighting reduces debugging time by up to 70%. Plus, because all processing happens in your browser (after upload), your sensitive data never leaves your device unless you choose to share.

Advanced users appreciate the XPath evaluator – simply type an expression and see which nodes match. For example, //price[text() > 15] highlights all books priced above $15. The tool also validates well‑formedness; a missing closing tag or unescaped ampersand is flagged immediately with line number.
