How to traverse a JSON file?

The JSON I have is mentioned below :-

{   head: {
    link: [],
    vars: [
      "CompanyName",
      "Company_Name",
     开发者_如何学C "Foundation_URI",
      "Foundation_Name",
      "Latitude",
      "Longitude"
    ]   },   results: {
    distinct: false,
    ordered: true,
    bindings: [
      {
        CompanyName: {
          type: "uri",
          value: "http://dbpedia.org/resource/United_Christian_Broadcasters"
        },
        Company_Name: {

I want to know that how can I traverse this JSON to get the values of the appropriate variables as mentioned in the JSON file. I would like to know this with respect to JavaScript as well as Java. Please let me know how to traverse this JSON so as to get data easily.

This is not a JSON string but luckily a YAML standrd format.

You can use YAML library to transverse your jSON-like string

Here is a rather simple tree traversal routine:

function traverse(o) {
  if( o instanceof Object ) {
    for( key in o ) {
      traverse(o[key]);
    }
  }
  else if( o instanceof Array ) {
    for( value in o ) {
      traverse(value);
    }
  }
  else {
    console.log(o);
  }
}
var q = { name : 'me', data : [ { a: 'a1', b: 'b1' }, { a: 'a2', b: 'b2'} ] };
traverse(q);

However, I think this is not quite what you're looking for. Please clarify and I will update my answer accordingly.

Following is a simple traversing of JSON object, this should help you undersatnd your JSON object normal traversing. Check the https://github.com/substack/js-traverse link for a detailed tutorial for complex traversing of any javascript object

<script language="javascript"> 

var emp = {"details" : [
             {
             "Name" : "Nitin1",
             "Salary" : 10000, 
             "DOJ" : "16th Sept 2010"
             }
            ,

             {"Name" : "Abhijit2", 
             "Salary" : 5000, 
             "DOJ" : "15th Sept 2010"}
            ,

             {"Name" : "Nilesh", 
             "Salary" : 50000, 
             "DOJ" : "10th Sept 2010"}

            ]
    };

document.writeln("<table border='1'><tr><td>Name</td><td>Salary</td><td>DOJ</td></tr>");
var i=0;
for(i=0;i<emp.details.length; i++)
{
  document.writeln("<tr><td>" + emp.details[i].Name + "</td>");
  document.writeln("<td>" + emp.details[i].Salary +"</td>");
  document.writeln("<td>" + emp.details[i].DOJ +"</td></tr>");
}
document.writeln("</table>");


</script>

If you only want to retrieve particular values - you do not need to traverse the entire JSON file.

This can be done in Javascript as follows:

Declared JSON variable:

var myJSONObject = {"bindings": [
        {"ircEvent": "PRIVMSG", "method": "newURI", "regex": "^http://.*"},
        {"ircEvent": "PRIVMSG", "method": "deleteURI", "regex": "^delete.*"},
        {"ircEvent": "PRIVMSG", "method": "randomURI", "regex": "^random.*"}
    ]
};

Fetch a particular value:

myJSONObject.bindings[0].method    // "newURI"

I do not use Java myself, but XML.java (documentation available here) allows you to convert the JSON into XML. Parsing an XML is easy - you will find plenty of tutorials on it for Java such as:
