Deciphering Local XML with Ajax

As I work on creating a local HTML file to display dynamic data from an XML file, I've encountered a problem. After inspecting the file in Chrome, it seems that my XML file is not being parsed due to it not being hosted on a webserver.

XMLHttpRequest cannot load data.xml. Cross origin requests are only supported for HTTP.

While there are some flags that could potentially resolve this issue, I am exploring alternative methods as I plan to share these files with others who may not be familiar with modifying browser settings. Hosting the files on a web server is also not an option for me at this time.

Thank you for any assistance you can provide.

Answer №1

You won't see any apparitions unless you configure a nearby server or store the XML document on your own hosting environment. Ajax is required to adhere to the same origin policy.

Answer №2

If you are open to utilizing a library, consider using jQuery's AJAX method for making a cross-domain request (though there may be limitations with jQuery in this scenario). JSONP is an option, but if you have XML data...

You can experiment by loading the data within a script tag and attempting to extract the innerHTML value without disrupting the script. Once you have retrieved the necessary text, remove the script element from the page. It may be possible to access the data before the browser attempts to interpret the script by attaching onload and onreadystatechange events to the script element.

var s = document.createElement('script');
s.src = '/path/to/file.xml';
s.onload = s.onreadystatechange = getData;
function getData(e)
{
  // Extract text from the script element
  // Remove event handler from the script element
  // Remove the script from the page
}
document.getElementsByTagName('body')[0].appendChild(s);

While untested, this approach has potential to be effective.

Answer №3

Have you considered the option of creating a local webserver? XAMPP is user-friendly and simple to set up, making it ideal even for beginners. Simply instruct them to place your files in the htdocs folder, launch xampp, and start the apache server.

Answer №4

If there is no strong justification for maintaining distinct html and xml files, consider embedding the data directly into the html file.

Answer №5

If Chrome is restricting the options you prefer for your application, it can be frustrating trying to make them work together. Even accessing through iframes and objects doesn't seem to solve the issue, as the load() method of createDocument isn't supported by Chrome (resulting in the same error). It seems like any workaround you attempt will just be a way to bypass Chrome's restrictions, which may not be ideal since they likely have valid reasons for implementing them.
