XHR Connector for Internet Explorer

Hello there! If you are new here, you might want to subscribe to the RSS feed for updates on this topic.

Below is a great code snippet to process XML dynamically through an XMLHttpRequest (XHR) request. From this further XSLT processing can be applied dynamically utilising Internet Explorers “fragment” transformations.

/* XHR Connector */
XMLReq = function() {
	this.adapter = false;
	/*@cc_on @*/
	/*@if (@_jscript_version >= 5)
		try {
			this.adapter = new ActiveXObject("Msxml2.XMLHTTP");
		} catch (e) {
			try {
				this.adapter = new ActiveXObject("Microsoft.XMLHTTP");
			} catch (E) {
				this.adapter = false;
			}
		}
	@end @*/
	if (!this.adapter && typeof(XMLHttpRequest) != 'undefined') {
		this.adapter = new XMLHttpRequest();
	}
};
XMLReq.prototype.adapter = null;
XMLReq.prototype.getDocument = function(sUrl) {
	this.adapter.open("GET", sUrl, false);
	this.adapter.send(null);
	//alert("Status = " + this.adapter.status + "n"+this.adapter.getAllResponseHeaders()+"nParse Error = " +this.adapter.responseXML.parseError.errorCode);
	// if XML sent as application/octet-stream!! you can't use responseXML in this instance instead must use responseBody
	return this.adapter.responseBody;
};

/*  The actual  */
var yourprocessorfunction = function() {};
var nameofcallvariable = new yourprocessorfunction();
yourprocessorfunction.prototype.data = null;
yourprocessorfunction.prototype.init = function() {
	// init vars
	this.data = this.XMLReq.getDocument("http://whereeveryourxmldocis");
};
/* Init */
function start() {
	nameofcallvariable.init();
}
window.onload = start;
