XML Formatter & Validator

คำถามที่พบบ่อย

Quick answers.

›What XML features does this support?

Attributes, nested elements, mixed content, CDATA blocks, comments, processing instructions and the XML declaration are all preserved. The formatter uses the browser's native DOMParser so anything your browser accepts is accepted here.

›What's the difference between Beautify and Minify?

Beautify adds indentation and line breaks for readability. Minify strips whitespace between tags while keeping text-node content intact — good for reducing payload size before sending XML over the wire.

›Does Validate catch every XML error?

It catches well-formedness errors (unclosed tags, mismatched attributes, stray ampersands). It does not validate against a DTD or XSD — that's a separate schema-validation step.

›Is my XML sent anywhere?

No. Everything runs in your browser — the parser, the formatter, the minifier. Your payload never leaves the page.
