XMLszabályok

XMLszabályok refers to the set of rules that govern the creation and structure of XML documents. XML, which stands for Extensible Markup Language, is a markup language designed to store and transport data. These rules ensure that XML documents are well-formed and can be processed consistently by different applications.

A fundamental XMLszabály is that every XML document must have a single root element. All other elements are nested within this root element. Elements must also have a closing tag, unless they are empty elements, which can be written as a self-closing tag. For example, `<element></element>` or `<empty_element/>`. Tag names are case-sensitive, meaning `<tag>` and `<Tag>` are treated as different elements. Attributes, which provide additional information about elements, must be enclosed in quotes, either single or double.

Furthermore, XMLszabályok dictate that certain characters have special meanings and must be represented using character entities if they are to be treated as literal characters. These include characters like `<`, `>`, `&`, `'`, and `"`. Properly formed XML documents are essential for data exchange and interoperability between systems. Adherence to these rules allows parsers to correctly interpret the structure and content of an XML document, making it a robust format for data representation.
