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 is completely free with no signup required.
