What is the best method to detect xml in JavaScript

What is the best method to detect xml in JavaScript

e.g. is it possible to detect the mime type of a document - particularly if it is text/xml in JavaScript.

this needs to work in Chrome.

thanks,

Josh

Solution

  • If you are using XMLHttpRequest to get this data, then you can simply check for the Content-Type header using the getResponseHeader method (granted that the server sends the appropriate headers).

    var getFile = function(address, responseHandler) {
  var req = new XMLHttpRequest();  

  req.open('get', address, true);  
  req.onreadystatechange = responseHandler;
  req.send(null);  
}

var responseHandler = function(resp) {
  if ( this.readyState < 4 ) { return; }
  console.log(this.getResponseHeader("Content-Type"));
};

getFile("http://zebrakick.com/some/file", responseHandler);

    (I seem to be using this code sample a lot...)
