JSON vs yaml vs XML

JSON
Http://www.json.org/json-zh.html

The following code shows its advantages.

VaR namestr = '[{"first": "San", "last": "Zhang", "Age": 24 },{ "first": "Si ", "last": "Li", "Age": 22}] ';
VaR nameobjs = eval ('+ namestr + ')');
For (var I in nameobjs )...{
Document. Write (nameobjs [I]. First + ',' + nameobjs [I]. Last + ',' + nameobjs [I]. Age + '<br> ');
}

JSON is out of the box with Ajax, and JavaScript built-in Parsing is converted to JavaScript objects.

Yaml
Http://yaml.org/
It seems that Ruby has a good support for it and is not familiar with Ruby. If you don't know whether Ruby is used, you can parse the yaml format.

XML, which is familiar to everyone.
