I'm trying to update the components metadata field using core service API's.We are having around 5000 components in that few of the components metadata field was updated and remaining does not contain any value.so i'm trying to update those components which doesn't contain metadata field value.
But I am facing issue after loading the xml from component metadata xml(Component.Metadata),but in the xml i'm not able to select the the node which I need to update.
Node test = componentFields.SelectSingleNode("//componentFields:fielname", componentFieldsNamespaceManager);
Node "test" will have null value if the components doesn't contains field value.
Please let me know is there any way to update the metadata field of the component using Core service API.
Actually I am new to Core Service Concept...can you please help me on this issue...
Thanks in Advance.
