4.2 YAML

The same data from Chapter 4.1 can be recorded in the YAML format:

cities:
- from:
  - Brussels
  - {to: London, distance: 322}
  - {to: Paris, distance: 265}
- from:
  - London
  - {to: Brussels, distance: 322}
  - {to: Paris, distance: 344}

Since the YAML format is just a different structure notation than JSON, the X-definition will be the same as in the previous Chapter 4.1:

<xd:def xmlns:xd="http://www.xdef.org/xdef/4.2" name="Test" root="Distancies" >
  <xd:json name="test">
    { "cities"  : [
        { %script = "occurs 1..*;",
          "from": [ "string();",
            { %script = "occurs 1..*;",
              "to": "jstring();",  "distance": "int();"
            }
    	  ]
        }
      ]
    }
  </xd:json>
</xd:def>
