Frequently Asked Questions
What is HTML/XML syntax?
HTML (HyperText Markup Language) and XML (eXtensible Markup Language) are both markup languages. HTML is used for creating web pages, while XML is designed to store and transport data. HTML has predefined tags, whereas XML allows users to define their own tags.
How is the XML data format structure different from JSON or YAML?
XML uses a tree structure with nested elements and attributes, while JSON uses key-value pairs and arrays. YAML is similar to JSON but is more human-readable and allows comments. XML is more verbose than both JSON and YAML, which can make it less efficient for data interchange.
