Problem with the export MS Project XML

Hello,
I have the same with MS Project 2010 when trying to open the xml file (export from Project'Or RIA 3.4.4). If something has been made to solve this, could you please provide the workaround?
Thanks!

Hello,
Thank you for your answer.
Here is the first 3 lines I have:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Project xmlns="schemas.NotAllowedScript680fbf756c480microsoft.com/project">
<Name>export_planning_20131008_125911.xml</Name>

I have tested with <Project> and I got the same message.

I also exported an empty project from MS Project in XML in order to compare with my export from Project'Or RIA. I noticed a UNIX/DOS format difference (Project'Or RIA is running on a Linux server whereas I try to open it under Windows) which I fixed without success (well, changing from UNIX to DOS was done with success, I meant that I got the same message again).

I have seen also a lot of variables which exists on one file but not on the other one, but I am novice into this and so not able to go further for now.

I went on MS website to check versus the MS Project XML format standards, but it can take time. So in the meantime, any other advise is welcome

Ok, I found it.

The problem was in the <Group> section of <Resource>.
The content was "<Group>Security & Compliance</Group>" and removing the ampersand character has fixed the import.

I suspect that other fields have the same constraint.

Thanks.
Just one more question: fixed for this specific field, or did you checked versus other ones?
