Dear All,  
I'm using node-red V3.0.1 and "node-red-contrib-opcua" version 0.2.295

Could someone tell me if is it possible, and how do to:

Scrape / browse an OPC-UA device (IP addres example opc.tcp://192.168.1.203:4840 ) to **obtain all the ns: "namespaceindex"** (example ns=4;i=16854528) available into the opc-ua device I'm scraping?

Thanks in advance.

Look examples OPCUA-TEST-NODES.json and browse nodes on first tab...
