XML Elements and Attributes

Estimated study time: 12 minutes.

XML documents are built from two core building blocks: elements and attributes. Knowing when to use each is key to designing clean, maintainable XML.

Elements

An element is a tag (and its content) that represents a piece of data. Elements can contain text, other elements, or both.

<student>
  <name>Rahul Verma</name>
  <age>24</age>
</student>

Attributes

An attribute provides additional information about an element, written inside its opening tag as a name-value pair.

<student id="102" status="active">
  <name>Rahul Verma</name>
</student>

Elements vs Attributes — When to Use Which

• Use an element when the data could have multiple values, sub-structure, or might need to grow over time.
• Use an attribute for simple, single-value metadata about the element itself, like an ID or a status flag.
