Hi is it possible to browse, from the client, a specific address space?
Since the browse method want to use nodeID, but I want to target a browse based on a specific address space.
How can this be achieved?

Sorry, I don’t understand what you mean with a specific address space. Each server has a single address space.

I mean those addressespaces which also exist on the sampleServer.

Is there a way for the client to spesifically get the nodes beloning to this addresse space.
I would believe so since an example client can highlight the specific nodes belonging to a address space.
Its just taht I dont see how it currently can be done.
A client is connecting to a server, but how can he get the nodes of that specific addresseSpace?

OK, now I got it. You mean namespaces.
No, there is no filter options for namespace in browse, so the only option is to filter the browse results in your client application.

There is a the NamespaceIndex in the NodeId of a NodeToBrowse.
Client can’t use it to specify which Namespace they want to browse ?

Well, it’s still possible that I did not get it right. I was considering that vonGohren wants to browse a single node and get only those references that target to nodes in a certain namespace.
Browse takes some options, e.g. NodeClass and ReferenceType, which you can use to limit the results (you can define these as property values for AddressSpace or use the version of browse, which takes these as arguments). But you cannot define the NamespaceUri or NamespaceIndex of the targets you wish to have.
But you are, of course, free to select only the nodes you need in the client application by looking at the NamespaceIndex or NamespaceUri of the target NodeIds (which are actually ExpandedNodeIds). Also you can use UaClient.getNamespaceTable() to convert between NamespaceIndexes and NamespaceUris, which may be what you are looking for?
