Что такое XML?

XML — расширяемый язык разметки используется для описания данных. Стандарт XML — это гибкий способ создания информационных форматов и обмена структурированными данными в электронном виде через общедоступный Интернет, а также через корпоративные сети.

Формат XML может использоваться любым лицом или группой лиц или компаний, которые хотят делиться информацией согласованным образом. XML на самом деле является более простым и удобным в использовании подмножеством стандартного обобщенного языка разметки (SGML), который является стандартом для создания структуры документа.

XML syntax rules are not simple, but with a few guidelines and examples, it’s easy to start using XML in your projects.

XML documents must have a top level element, must end with a close tag, XML tags are case insensitive, must be nested correctly XML attributes must be quoted.

Is login required to save XML data?

No. It’s not required to save and share code. If XML data is saved without login, it will become public. To make XML data private please login and save the links.

Validates the XML string/file against the XSD string/file. XSD files are «XML Schemas» that describe the structure of a XML document. The validator checks first the XML, meaning that your XML string/file must be parsable using a XML parser, and only then does it validate your XML against the XML Schema.
