Mapping Rules

Mapping Rules

• Namespaces, namespace prefixes, comments, and processing instructions are all ignored.
• Elements with no attributes and no content or whitespace-only content become null.
• Elements with no subelements and no attributes become the text, numeric, or boolean value of the element content.
  ActionScript

  <x>Hello</x>
  becomes
  "Hello"

  
  
• Elements with attributes or child elements become a record.
• Nested element names (sans any namespace prefix) become record fields
  ActionScript

  <x>
  <y>Hello</y>
  </x>
  becomes
  {
  "y": "Hello"
  }

  
  
• Attributes become record fields prefixed with @.
  ActionScript

  <x>
  <y z="1"/>
  </x>
  becomes
  {
  "y": {
  "@z": 1
  }
  }

  
  
• If an element has attributes and non-empty text-only content, then the text content becomes a record field named value.
  ActionScript

  <x>
  <y z="1">Hello</y>
  </x>
  becomes
  {
  "y": {
  "@z": 1,
  "value": "Hello"
  }
  }

  
  
• Multiple elements with the same name at the same level become multiple values of the same field.
  ActionScript

  <x>
  <y>Hello</y>
  <y>Goodbye</y>
  </x>
  becomes
  {
  "y": ["Hello", "Goodbye"]
  }

  
  
• If an element has mixed content (intermixed text and elements), then the text is ignored.
  ActionScript

  <x>
  <y>Hello</y>
  Something in between
  <y>Goodbye</y>
  </x>
  becomes
  {
  "y": ["Hello", "Goodbye"]
  }
