How can I generate a server AddressSpace from a XML nodeset file?

Question

I am getting familiar with the node-opc-ua project and I want to generate a servers address space from a given nodeset (xml file) automatically.

Is there a possibility?

I've found a function called `generate_address_space(addressSpace, xmlFiles, callback)` in the file _load_nodeset2.js_. Unfortunately there is no documentation about this. Maybe someone has a hint for me? — kratsching, Nov 29 '16 at 14:43

You can specify more than one nodeset2.xml files to load to enrich the address space. Here is a simplified example.

var opcua = require("node-opcua");

var nodeset_filename1 ="CustomAddressSpaceNodeset2.xml";
var nodeset_filename2 ="OtherCustomAddressSpaceNodeset2.xml";

var server_options = {
   /* [...] */
   nodeset_filename: [
     opcua.nodesets.standard_nodeset_file,
     nodeset_filename1,
     nodeset_filename2 
   ]
   /*  other server options here */
};

var server = new opcua.OpcuaServer(server_options);

server.start(function (err) {
});

Is there a solution for the "regular" https://github.com/OPCFoundation/UA-.NETStandard ? – Houve Apr 11 '18 at 10:31
Hello guys, I am trying to use your approach with an Information Model that I created using the SIOME tool. I always get an error: this.bodyXML = this._cloneFragment.value; Do you know why? – Andrea Fresa May 20 '20 at 08:30
Andrea, the xml file would require closer investigation, I suggest you contact the author of the node-opcua stack directly. – Etienne May 29 '20 at 15:31
