XML Formatter & Validator
Format, validate, and minify XML with namespace-aware parsing, CDATA preservation, and XPath queries. Uses DOMParser for robust XML 1.0 compliance.
How to Use XML Formatter in 3 Steps
- Configure. Paste XML into the input. DOMParser validates and structures the document with namespace awareness.
- Process. Pick mode: Prettify (indented, well-formed), Minify (compact single-line), or Validate (check well-formed status with error line/column).
- Export. Optional: run an XPath query against the parsed document to extract specific nodes without leaving the tool.
Why XML Formatter on Pixlane
XML formatting is used for SOAP payload review, RSS/Atom feed inspection, OOXML / SVG editing, and legacy system debugging. Pixlane uses the browser's native DOMParser with the application/xml MIME type: getting true XML 1.0 behavior (CDATA, processing instructions, namespaces) rather than HTML quirks.
- DOMParser XML Mode: Parsed with application/xml MIME, true XML 1.0 compliance. CDATA, PIs, namespaces, and entities are handled correctly.
- XPath Queries: Native document.evaluate() supports XPath 1.0 expressions to extract elements, attributes, or text, no separate XPath tool needed.
- CDATA & PI Preservation: <![CDATA[...]]> blocks, <?xml-stylesheet?> processing instructions, and doctype declarations are preserved through format/minify.
- Precise Error Reporting: Invalid XML shows exact line, column, and cause via browser's parseerror document, faster debugging than grep-style regex validators.
Frequently Asked Questions
What XML spec is supported?
XML 1.0 (Fifth Edition) and XML Namespaces 1.0. What browsers support natively. XML 1.1 is rare in practice; most standards (RSS, Atom, SOAP, SVG) use XML 1.0.
How does XPath work?
Uses document.evaluate() with your XPath expression. Supports XPath 1.0 syntax: /root/child, //elem[@attr], position(), count(), etc.
Is my XML private?
Yes. Parsing and formatting happen entirely in your browser. XML content, which may contain SOAP requests with credentials, never leaves your device.
Is this tool free?
Yes. XML Formatter on Pixlane currently requires no signup for core use; tool-specific limits may apply.
