Technical Details

XML Structure

XML relies on rigorous opening and closing tags `...`. Attributes must be quoted, and HTML self-closing rules don't always apply (e.g., `
` is valid, `
` is not).

Whitespace Handling

Whitespace between tags is notoriously tricky in XML. Our tool normalizes this space to create a clean indentation structure while preserving whitespace *inside* text nodes where it matters.

Nesting Depth

Deeply nested XML files (common in enterprise configs) are handled gracefully, ensuring that every level of the tree is visually distinct.
