What is XML?
XML (eXtensible Markup Language) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. It is widely used for configuration files, data exchange (SOAP, RSS, Atom), and document storage.
Key XML Features
Self-descriptive
XML uses custom tags to describe data structure, making it easy to understand the content and hierarchy at a glance.
Platform Independent
As plain text, XML works across all platforms, programming languages, and systems without compatibility issues.
Extensible
You can define your own tags and document structure using DTD or XML Schema to suit any data model.
Frequently Asked Questions
Well-formed XML follows the basic syntax rules of XML (proper nesting, closing tags, single root element). Valid XML is well-formed AND conforms to a schema (DTD, XSD) that defines the allowed structure and data types.
No, this tool checks for well-formedness only (syntax correctness). Schema-based validation against DTD or XSD is not supported in the browser natively.
The browser's native document.evaluate() supports XPath 1.0. This covers most common queries including axes, predicates, and functions like contains(), text(), and @attribute.
