DOMParser Syntax Tree Reconstruction
Native browser engines include the DOMParser API (`new DOMParser().parseFromString(xml, 'text/xml')`), which parses raw markup into a structured XML Document Object Model.
Traversing node trees recursively allows formatters to apply consistent 2-space or 4-space indentation while preserving CDATA blocks and self-closing tags (<tag />).
Production XML Minification
Minification strips redundant indentation, line breaks, and developer comments between closing and opening tags (`> <`), reducing XML sitemap and SVG file sizes by 20% to 35% before production deployment.
Step-by-Step Tutorial
Paste Raw XML Markup
Paste your sitemap.xml, RSS feed, or SVG code into the editor.
Select Indentation or Minify
Choose 2-space indent for human debugging or Minify for production deployment.
Copy or Download Clean File
Copy validated markup with one click or save as a validated .xml file.

Frequently Asked Questions
Does XML formatting alter CDATA section content?
No. Strict XML parsers preserve exact whitespace inside `<![CDATA[...]]>` blocks to prevent code corruption.
Can formatting repair malformed XML?
If an XML document contains fatal syntax errors (e.g. mismatched tags), the parser flags the exact line and column error for correction.
