C++ XMP sample code to get the contents of an array property.

void XmpGetArray(void)
    {
    // Get the contents of a Bag, Seq, or Alt array property.
    CkXmp xmp;
    xmp.UnlockComponent("anything for 30-day trial");

    bool success = xmp.LoadAppFile("AgencyPhotographer-Example.jpg");
    if (!success)
	{
	xmp.SaveLastError("lastError.txt");
	return;
	}

    // Get the 1st XMP metadata document contained within the JPG.
    // (It is unusual to have more than a single XMP embedded in a JPG or TIFF)
    CkXml *xml = xmp.GetEmbedded(0);
    if (!xml)
	{
	printf("XMP not found!\n");
	return;
	}

    CkStringArray strArray;

    xmp.GetArray(*xml,"dc:subject",strArray);

    int i;
    int n = strArray.get_Count();
    
    for (i=0; i<n; i++)
	{
	printf("%s\n",strArray.GetString(i));
	}

    delete xml;
    
    return;
    }
