JSON vs XML


Both JSON and XML can be used to receive data from a web server.

The following JSON and XML examples both define an employees object, with an array of 3 employees:

JSON Example

{"employees":[
  { "firstName":"John", "lastName":"Doe" },
  { "firstName":"Anna", "lastName":"Smith" },
  { "firstName":"Peter", "lastName":"Jones" }
]}



XML Example

<employees>  <employee>
    <firstName>John</firstName> <lastName>Doe</lastName>
  </employee>
  <employee>
    <firstName>Anna</firstName> <lastName>Smith</lastName>
  </employee>
  <employee>
    <firstName>Peter</firstName> <lastName>Jones</lastName>
  </employee>
</employees>



 JSON is Like XML Because

Both JSON and XML are "self describing" (human readable)
Both JSON and XML are hierarchical (values within values)
Both JSON and XML can be parsed and used by lots of programming languages
Both JSON and XML can be fetched with an XMLHttpRequest


JSON is Unlike XML Because

JSON doesn't use end tag
JSON is shorter
JSON is quicker to read and write
JSON can use arrays

The biggest difference is:
 XML has to be parsed with an XML parser. JSON can be parsed by a
standard JavaScript function.

Why JSON is Better Than XML

XML is much more difficult to parse than JSON.
JSON is parsed into a ready-to-use JavaScript object.

For AJAX applications, JSON is faster and easier than XML:
Using XML

Fetch an XML document
Use the XML DOM to loop through the document
Extract values and store in variables

Using JSON

Fetch a JSON string
JSON.Parse the JSON string

Als ich letztens mit dem Regionalzug durch das herbstliche Brandenburg fuhr, sah ich eine auffällige Anzeige, die mich neugierig machte. Ich war schon länger auf der Suche nach einer Plattform, die eine gute Mischung bietet. Bei capospin habe ich dann genau das gefunden, was ich suchte. Besonders die Auswahl im Bereich Poker hat mich überzeugt. Nachdem ich anfangs ein paar Rückschläge bei den Slots Online hinnehmen musste, kam plötzlich die große Wende und ich konnte einen ordentlichen Betrag gewinnen.

It's fascinating to see how different data formats like JSON and XML serve similar functions yet have distinct advantages. I've always preferred JSON for its simplicity and ease of use, especially in web applications. It really shines when you consider how quickly it can be parsed into JavaScript objects. Speaking of efficiency, have you explored the creative possibilities in coding? Platforms like Infinite Craft can really enhance your projects!
