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

void XmpGetSimpleStr(void)
    {
    // Fetches a simple XMP string 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;
	}

    CkString str;
    xmp.GetSimpleStr(*xml,"Iptc4xmpCore:Location",str);
    printf("Location: %s\n",str.getString());

    xmp.GetSimpleStr(*xml,"Iptc4xmpCore:CountryCode",str);
    printf("CountryCode: %s\n",str.getString());

	delete xml;
	
    return;
    }
