Get Simple Date/Time Property

C++ source code to fetch a simple date/time property from an XMP embedded within a JPG or TIF.

void XmpGetSimpleDateTime(void)
    {
    // Fetches a simple XMP date/time property from XMP metadata embedded
    // in a JPG or TIF.
    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;
	}

    // Get the xap:ModifyDate, which looks like this:
    // <xap:ModifyDate>2005-03-13T02:00:54-06:00</xap:ModifyDate>
    SYSTEMTIME sysTime;
    xmp.GetSimpleDate(*xml,"xap:ModifyDate",sysTime);
    printf("ModifyDate: %d/%d/%d %d:%d:%d\n",
	sysTime.wDay,sysTime.wMonth,sysTime.wYear,
	sysTime.wHour,sysTime.wMinute,sysTime.wSecond);

	delete xml;
	
    return;
    }
