Defiant.js - searching and processing JSON with XPath and XSLT

["Costello, Roger L." <costello@mitre.org>]

Hi Folks,

A powerful mix of XML and JSON:

	Defiant.js provides the ability for you to perform lightning fast searches 
	on JSON structures using XPath expressions and enables XSL transformations 
	using JSON data.  

Here are some examples that show using XPath on JSON:

var obj = {"car": [{"@id": 10, "@color": "silver", "name": "Volvo"},
                          	  {"@id": 11, "@color": "red",    "name": "Saab"},
		  {"@id": 12, "@color": "red",    "name": "Peugeot"},
		  {"@id": 13, "@color": "yellow", "name": "Porsche"}
		],
	"bike": [{"@id": 20, "@color": "black", "name": "Cannondale"},
		{"@id": 21, "@color": "red",   "name": "Shimano"}

         	]},

search = JSON.search(obj, '//car[@color="yellow"]/name');

console.log( search );

// ["Porsche"]

var reds = JSON.search(obj, '//*[@color="red"]');

for (var i=0; i<reds.length; i++) {
	console.log( reds[i].name );
}

// Saab
// Peugeot
// Shimano
