Frequently Asked Questions about XML Formatter
What XML features are supported?
xml-formatter handles all standard XML: elements, attributes, namespaces, CDATA sections, comments, processing instructions, and self-closing tags.
Can I validate XML syntax without reformatting it?
Yes — clicking 'Format' also validates the XML structure. If the XML is invalid, an error message pinpoints the issue. You can also use the Minify button which also validates.
When should I use XML minification?
Minify XML when you need to reduce payload size for API calls, configuration files, or web service requests. Minified XML removes all whitespace and newlines between tags, reducing file size without changing data content.
