Data grabing from Webpage

KNIME Extensions
,
#1

Dear community,
i have a short question and perhaps someone can help me.

I developed a KNIME Workflow and it works fine but now i have to enhance this workflow. I need to include the exchange rates from https://wechselkurse-euro.de/. Is there any possibiliy to use one of the nodes to grap this data from this webpage to further process them within the workflow?
I have no access to the database behind this website so for me it´s not possible to connect directly with this database.

The calculation afterwards is then no problem eny more.
Thank you in advance for your support.

The archive data can be accessed here (no data on weekends):
https://wechselkurse-euro.de/archiv-wahrungskurse/2022-02-14/

This could be scraped with a Webpage Retriever node and some XPath queries. Make sure to set a delay, you don’t want to DDoS that server. Especially because this one takes quite a while to respond.

If you need more help, please tell us how the output should look like (do you need only the current data, or historical data as well, what format, …).
