loading XML

I am new to RTI DDS and I am having issues with the xml file defined in the NDDS_QOS_PROFILES environment variable. I have defined this environment variable to point to my xml file. However when I run my application and try to do the following, my participaint doesn't get created.

(using c++11)

In my application, I have read in the environment variable and outputted this in my log to verify there were no issues with that.

I have also invalidated the <dds> tag in my xml file, but haven't seen any error message.

|------image_types.xml

|------coordinate_systems.xml

|---MY_RECORDING_SERVICE.xml

Inside my MY_RECORDING_SERVICE.xml I'm including these xml generated as follow: 

Is there a programmatic method of verifying the XML file was loaded.

For our test verification we have to simulate various possible failures.
One of the possible failures is a missing xml file. In software we need
a method to check if an XML file was loaded or if defaults values are being used.
