Question Updated for Bounty
In Flash I need to load a dynamically generated XML file, which is created using PHP.
I\'m using the [Bulk-loader librar
From your output:
Error #1088: The markup in the document following the root element must be well-formed.
It seems that the problem is not with the loader but with the PHP output. Check to make sure your output looks as expected by accessing the generated XML directly from your browser and downloading it. You may be able to spot the error in the output if you go through it in a text editor line-by-line, or you could try using an XML editor and see if it finds issues.
