Format and validate XML documents in a clean workspace.
Master well-formed XML documents, attribute namespaces, and structural JSON conversions.
Unlike forgiving HTML, XML enforces uncompromising syntax: every opening tag must have an explicit closing companion or self-close (<item />), tag identifiers are case-sensitive, attribute values must be enclosed in quotes, and exactly one root node must encompass the entire tree hierarchy.
To embed unescaped code, SQL snippets, or raw symbols without triggering parse errors, XML provides <![CDATA[ ... ]]> blocks. XML namespaces (xmlns) prevent tag collisions when merging multi-schema documents (such as SOAP RPC envelopes, SVG vector nodes, or SAML auth assertions).
JSON natively represents booleans, numbers, arrays, and objects, while XML treats content as text and separates attributes from inner children (<node id="1">value</node>). Translating XML into JSON adopts convention patterns like BadgerFish where attributes are prefixed with "@" and repeating siblings collapse into JSON arrays.
"Well-formed" XML satisfies fundamental XML 1.0 grammar rules. "Valid" XML strictly conforms to a formal Document Type Definition (DTD) or XML Schema (XSD).
No. Formatting, syntax validation, and DOM tree traversal run locally inside your browser memory.
Use predefined entity references (<, >, &, ", ') or wrap the block inside a <![CDATA[ raw data ]]> section.
