A property of an element that consists of a name and a value separated by an equal sign and contained within the start-tags after the element name. In this example, <Price units='USD'>5</Price>, units is the attribute and USD is its value, which must be in single or double quotation marks. Attributes can reside in the document or document type definition (DTD). Elements may have many attributes but their retrieval order is not defined.

DOM views the parsed document as a tree of objects.
