Get Structure Member Value

C++ XMP sample code to get the value of a structure member.

void XmpStructMemberValue(void)
    {
    // Get the value of a structure member (in an XMP structure 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;
	}

    // Gets the CiAdrCity member of the CreatorContactInfo structure:
    CkString strValue;
    xmp.GetStructValue(*xml,"Iptc4xmpCore:CreatorContactInfo",
	"Iptc4xmpCore:CiAdrCity",strValue);

    printf("%s\n",strValue.getString());

    delete xml;
    
    return;
    }
