Load XML error

I am using the professional edition of DHTMLX grid. I am writing an Ruby on Rails application, wherein I require to save all the contents of the grid to the database at once on submit. I tried using the sample “02_all_at_once.html” to achieve this. But, I am getting an error - “Error Type: LoadXML Description: Incorrect XML”. Kindly help me solve this problem.
The line that is throwing the error is - mygrid.loadXML("/php/get.php");
Thanks in advance

You need to replace
with path ro RoR controller which will return XML data for the grid
