// by Mark Hicken (nekcih@yahoo.com)

// depends on jquery 1.1.2 or later

// EXAMPLE USAGE

// set up success and failure functions
docOnLoad = function(xmlDoc) { alert("XML data OK: "+xmlDoc.responseText); }
docOnFailure = function(xmlDoc) { alert("Unable to communicate with server.\r\nPlease try again in a moment.\r\n\r\nStatus: "+xmlDoc.statusText); }

// execute asynchronous load
window.onload = function() { loadXMLDoc('myDoc.xml',  docOnLoad, docOnFailure); }
// or execute synchronous load (waits for response)
window.onload = function() { loadXMLDoc('myDoc.xml',  docOnLoad, docOnFailure, false); }
