A Workaround for XML Files Too Big for Ajax to Handle

A simple way to transfer XML documents onto a server is to use an Ajax-driven Web interface to upload the files. However, this approach won’t work for huge XML files because Ajax doesn’t support uploading of files that large. In her PHPBuilder.com article, Octavia Andreea Anghel demonstrates an innovative solution for transferring huge XML documents on the server via a Web interface using Ajax and the GET method. The solution works like this:

1. Transform the XML documents into a character string.
2. Split the character string into equal chunks (400 characters).
3. Save each chunk as a value in an array.
4. Transfer the chunks one by one using the Ajax mechanism into the final XML document.
