Hi @huynhduc , the “Noop” node is in the Nodepit powernodes and are available from Nodepit, and the installation instructions are here should you wish to install them:
However, I have updated the components in the sample workflow so that they no longer use the Noop nodes,. I still recommend the powernodes, but they shouldn’t be necessary now to get these components working.
It’s probably best to redownload the demo workflow:
This should then have the latest versions of the components, or you can manually trigger an update of the components.
Once working, the workflow gives examples of both these “splitter” components, but if you have any queries on how to make them work, let me know.
For background on the origins of the “Regex Multi Row Splitter” component, see this thread:
