XML Parser

What is XML Parser

Last reviewed: April 18, 2026

XML (Extensible Markup Language) is a strict, tag-based format used for documents, SOAP APIs, RSS feeds, and many enterprise and publishing systems.

XML Parser validates your XML with the browser's DOMParser, then pretty-prints it with clean two-space indentation — exposing any parse errors with line and column context.

It's a convenient way to reformat SOAP payloads, RSS / Atom feeds, Android layouts, SVG snippets, or any other XML you're trying to read by hand.

Why use it

• Debug SOAP or Atom feed issues.
• Read Android layout or XAML files.
• Clean up SVG copy-pasted from design tools.
• Verify XML before pushing to an API that rejects malformed docs.
• Format legacy XML configuration files.

Features

• Browser DOMParser validation
• Two-space indentation
• Preserves namespaces, attributes, CDATA
• Error output with line context
• Local-only XML Parser processing keeps data in-browser

How to use XML Parser

1. Paste XML. Drop any XML document.
2. Click Run. The parser validates and pretty-prints the output.
3. Copy result. Use the formatted XML in your app or documentation.

Example (before/after)

<root><user id="7"><name>Ada</name></user></root>

<root>
  <user id="7">
    <name>Ada</name>
  </user>
</root>
