Hi @Shoumo -
To get the Palladian nodes, you must now use a separate update site as described by @qqilihq in this post. Note that you should change the update site URL to match the version of KNIME you’re using (probably 4.1):
This should get you the required nodes, with the exception of the NekoHtmlParser. I wasn’t familar with this node, but I poked around on Nodepit and found that using the HtmlParser node is now recommended as a replacement:
Maybe Philipp can tell you more.
(On a side note, note that in most cases using deprecated nodes are fine - they should still work, it’s just they’ve been replaced by more up-to-date functionality. I think the main issue in the case of this workflow is not that the nodes are deprecated, but that the extension containing them moved to a different update site.)
Hope this helps!
