Which term best describes the structure XML uses to organize data?

• A. Nodes
• B. Tags
• C. Elements
• D. Schemas

Answer: (B)

Tags mark the boundaries and names of the data, showing how XML is organized. Each start tag and end tag encloses content and defines an element, and the nesting of those tagged regions creates the document’s hierarchy. The actual containers of data are called elements, but it’s the markup in the tags that defines where each element begins, ends, and how it relates to others, which is what we mean by the structure XML uses. Schemas describe rules for structure but not the real markup layout, and nodes are a concept from how XML is represented in memory rather than the markup that organizes it. So the term that best describes how XML structures data is tags.
