GET Request problem

I am a new joiner to the Knime. I hope my question here is not too stupid :stuck_out_tongue:

There are 2 workflows in the file,
-the 1st flow I try is with the node “get request”, I supposed I can use “json path” node afterwards to extract data, however, I dont know why is not working
-then i try to find a solution in the forum, I saw someone share another workflow with node “HHTP retriever”, I followed, but it fails again

May anyone tell me what’s wrong there?

Hi Jelly,

Your URL is not JSON but HTML format. You can e.g. use the HTML Parser node connected to the HTTP Retriever to parse it, if this is what you’re looking for:

Afterwards, you can treat it e.g. with the XPath node to extract specific parts of the parsed HTML DOM:

Thank you so much, Philipp! Your explanation is very clear :star_struck:

But I just have another problem here, see if you or other fellows can help :stuck_out_tongue_closed_eyes:

I use some online XPath tester, the path worked

But I don’t know why I input the same path into the node, the result shows nothing

You need to prefix element names with dns: so that they work properly (see the “Namespace” tab in the XPath node configuration). Thus, the XPath query should be:


I have updated the workflow which extracts all the h1 headlines and put it for you to my NodePit Space for you. Hope this helps!



Thank you again!! I am self-learning this language, you helped a lot :bowing_woman:
