Frequently Asked Questions
What is XML?
XML (eXtensible Markup Language) is a markup language for storing and transporting data. Unlike HTML, XML tags are not predefined - you create your own. XML is used in configuration files, data exchange, and document formats like SVG and RSS.
What is the difference between XML and JSON?
XML uses tags with opening/closing elements and supports attributes, comments, and namespaces. JSON uses key-value pairs and is more compact. JSON is preferred for APIs, while XML is common in enterprise systems, configuration, and document formats.
How do I validate XML?
Paste your XML into this tool - if it's malformed, you'll see an error message. Common XML errors include unclosed tags, mismatched tag names, invalid characters, and missing root elements.
What is well-formed XML?
Well-formed XML follows syntax rules: single root element, properly nested and closed tags, case-sensitive tag names, quoted attribute values, and properly escaped special characters (<, >, &, etc.).
