DTD Elements vs Attr

This lesson is part of XML · All levels

Summary

Elements and attributes can store similar information, but there are standard guidelines for selecting them. Attributes are suitable for short, single-text metadata, while long, multi-valued, or structured data should be placed as elements. Attributes are also non-sequential and cannot have children, so they are less flexible for the data that may develop.

Key points

Attributes can only contain a single text, without children.
Attributes do not have a sequence between other attributes
Multi-valued or long-term data is better as an element
Attributes that fit metadata such as category, gender, orientation
Selecting elements makes it easier to add data later on
