XML Attributes:

XML attributes with an example:

Consider an XML document representing information about a product:

        

        <product id="12345" category="Electronics" brand="Samsung">
        <name>Smartphone</name>
        <price currency="USD">500</price>
    </product>
    
      

In this XML document, the <product> element has three attributes:

1. id Attribute:

   • The id attribute has a value of "12345", which serves as a unique identifier for the product.

2. category Attribute:

   • The category attribute has a value of "Electronics", indicating the category to which the product belongs.

3. brand Attribute:

   • The brand attribute has a value of "Samsung", specifying the brand of the product.

Attributes provide additional information about elements in XML. Here's a breakdown of attributes in XML:

• Syntax: Attributes are specified within the start tag of an element. They consist of a name-value pair, where the name is followed by an equal sign (=) and the value enclosed in double quotes (").
• Uniqueness: Attribute names within the same element must be unique.
• Purpose: Attributes are typically used to provide metadata or additional properties associated with an element.
• Accessing: In XML, attribute values are accessed using the element's name followed by the attribute name, such as product[@id] to access the id attribute of the <product> element.
• Order: Attributes within an element are unordered, meaning their sequence does not matter.

In the provided example, the attributes id, category, and brand provide additional information about the product element, enhancing its semantics and allowing for more detailed description of the product.
