Cannot read from text file, always empty output. I think I might be missing something really important here, but whatever I tried I cannot read one line text file.
So it looks like your binary source key is FileData if you update your Move Binary Data node to use that and disable Set All Data as there is no JSON data it should work and you will have something like the below.
This time you have changed the property name in the Read Binary Files node to data, What ever you have in the property name here is what you need to use for the Source Key value on the Move Binary Data node.
Got it this time. Thanks for your attention.
I have extracted portion of an HTML file, now I need to extract all href values from that HTML, I am about to use regex for that but can you give me a hint which node to use for such kind of regex extraction? And how to add the extracted items to a list?
Hello @Jon,
Thanks for your response. I tried to use the HTML node, however it only does support selectors as you said, not regex, or at least I don’t see how can I use regex to extract the hrefs from the html source. Can you show an example if you don’t mind?
Below is a workflow I use to get the hrefs from our integrations page, I have changed it to save the response as a file rather than json but hopefully this helps.
Thanks for your hints and time again.
This is actually my first time building something with N8N and I have some understanding problems as of how some of the nodes behave and work.
I am trying to build a single automation, what it does:
goes to website of ElectrumLTC
checks if there is new version
if there is new version online which is different from the local version then it goes again to the website, scrapes the href values in part of the downloaded HTML, if not - it exits
creates new folder with the new version
downloads all new version files in that folder
reports Job done
exit task
With your guidance I managed to go further into the creation and got it this far:
Now I am stuck again, I extracted the href values and now I don’t know how to loop trough the lists of file and download them. Practically I do not know how to process from this point, but I guess I do something wrong again with the last “Item List” node.
I get the hrefs in the last HTML2 node, then I don’t see the list doing something any further for some reason.
