Basic XML Examples

These fundamental examples demonstrate core XML concepts and syntax.

Example 1: Simple XML Document

XML
<?xml version="1.0" encoding="UTF-8"?>
<message>
  <text>Hello, World!</text>
</message>

What This Example Demonstrates:

  • •XML Declaration: <?xml version="1.0" encoding="UTF-8"?> specifies version and encoding
  • •Root Element: <message> contains all other elements
  • •Child Element: <text> nested inside root
  • •Proper Nesting: All tags properly opened and closed

Use case: Simple messages, configuration values, basic data storage

Example 2: XML with Attributes

XML
<?xml version="1.0" encoding="UTF-8"?>
<user id="12345" status="active">
  <name>Alice Johnson</name>
  <email verified="true">[email protected]</email>
  <age>28</age>
  <balance currency="USD">1250.50</balance>
</user>

What This Example Demonstrates:

  • •Element Attributes: id="12345" and status="active" provide metadata
  • •Mixed Content: Elements contain both attributes and text content
  • •Boolean Attributes: verified="true" uses quoted text for boolean
  • •Descriptive Attributes: currency="USD" describes the balance unit

Use case: User profiles, database records, entity representations

Example 3: Repeated Elements (List Pattern)

XML
<?xml version="1.0" encoding="UTF-8"?>
<colors>
  <color>red</color>
  <color>green</color>
  <color>blue</color>
  <color>yellow</color>
</colors>

What This Example Demonstrates:

  • •List Pattern: Multiple elements with the same name represent a collection
  • •Container Element: Parent <colors> groups related items
  • •Order Preserved: Elements maintain their order in the document
  • •Simple Values: Each element contains plain text content

Use case: Lists, collections, tags, options, array-like data

Nested XML Examples

Real-world XML often contains nested elements to represent complex hierarchical data relationships.

Example 4: Nested Elements

XML
<?xml version="1.0" encoding="UTF-8"?>
<employee>
  <id>12345</id>
  <personalInfo>
    <name>Sarah Williams</name>
    <contact>
      <email>[email protected]</email>
      <phone type="mobile">+1-555-0123</phone>
    </contact>
    <address>
      <street>123 Main St</street>
      <city>Portland</city>
      <state>OR</state>
      <zipCode>97201</zipCode>
    </address>
  </personalInfo>
</employee>

What This Example Demonstrates:

  • •Deep Nesting: Three levels of hierarchy (employee → personalInfo → contact)
  • •Logical Grouping: Related information grouped together (contact, address)
  • •Mixed Attributes: type="mobile" provides metadata
  • •Hierarchical Structure: Clear parent-child relationships

Use case: Employee records, user profiles, complex data models

Example 5: Collection of Complex Elements

XML
<?xml version="1.0" encoding="UTF-8"?>
<catalog>
  <product id="1">
    <name>Laptop Pro</name>
    <price currency="USD">999.99</price>
    <inStock>true</inStock>
    <specifications>
      <processor>Intel i7</processor>
      <ram>16GB</ram>
      <storage>512GB SSD</storage>
    </specifications>
  </product>
  <product id="2">
    <name>Wireless Mouse</name>
    <price currency="USD">29.99</price>
    <inStock>true</inStock>
    <specifications>
      <connectivity>Bluetooth</connectivity>
      <battery>AA</battery>
    </specifications>
  </product>
  <product id="3">
    <name>Mechanical Keyboard</name>
    <price currency="USD">79.99</price>
    <inStock>false</inStock>
    <specifications>
      <switches>Cherry MX Blue</switches>
      <backlight>RGB</backlight>
    </specifications>
  </product>
</catalog>

What This Example Demonstrates:

  • •Collection Pattern: Multiple <product> elements of same type
  • •Consistent Structure: Each product has same base fields
  • •Nested Complexity: Each product contains nested specifications
  • •Flexible Content: Specifications vary by product type

Use case: Product catalogs, inventory systems, e-commerce APIs

Example 6: Deeply Nested Organizational Structure

XML
<?xml version="1.0" encoding="UTF-8"?>
<company name="TechCorp">
  <department name="Engineering">
    <team name="Backend">
      <employee id="101">
        <name>David Lee</name>
        <role>Senior Developer</role>
        <skills>
          <skill>Python</skill>
          <skill>Java</skill>
          <skill>Docker</skill>
        </skills>
      </employee>
      <employee id="102">
        <name>Emma Wilson</name>
        <role>DevOps Engineer</role>
        <skills>
          <skill>AWS</skill>
          <skill>Kubernetes</skill>
          <skill>CI/CD</skill>
        </skills>
      </employee>
    </team>
  </department>
</company>

What This Example Demonstrates:

  • •Multiple Levels: Company → Department → Team → Employee → Skills
  • •Hierarchical Data: Represents real organizational structure
  • •Mixed Patterns: Combines single elements and collections
  • •Attributes for Names: Using name attribute for identifiers

Use case: Organizational charts, menu structures, nested categories

Configuration File Examples

XML is widely used for configuration files in enterprise applications and build tools.

Example 7: Application Configuration

XML
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <appSettings>
    <add key="Environment" value="production" />

    <add key="EnableCaching" value="true" />
  </appSettings>
  <connectionStrings>
    <add name="DefaultConnection" 
         connectionString="Server=db.example.com;Database=mydb;User Id=admin;" />
  </connectionStrings>
  <features>
    <feature name="DarkMode" enabled="true" />
    <feature name="BetaFeatures" enabled="false" />
  </features>
</configuration>

What This Example Demonstrates:

  • •Key-Value Pattern: <add key="..." value="..." /> for settings
  • •Self-Closing Tags: Empty elements use />
  • •Grouped Settings: Settings organized by category
  • •Common .NET Pattern: Follows ASP.NET configuration style

Use case: Web.config, app.config, .NET applications

Example 8: Maven Build Configuration (pom.xml)

XML

XML Syntax Rules to Remember

1.
Case-Sensitive: <Name> and <name> are different tags
2.
All Tags Must Close: Use <tag></tag> or <tag /> for empty elements
3.
One Root Element: Document must have exactly one root element containing everything
4.
Proper Nesting: Close inner tags before outer tags
5.
Quote Attribute Values: Use double or single quotes: attr="value"
6.
Escape Special Characters: Use &lt; &gt; &amp; &quot; &apos;

Pro Tip: Always validate your XML using an XML validator or XML formatter to catch syntax errors before using it in your application.
