Hi Robikozo,
Below code will fetch any data from a webpage.
All you have to do is look into the source html of the webpage and copy paste the html part you are interested in.
Take into account that hard returns have to be defined as /n
Replace the part you want to fetch with (.-)
Below example fetched the latest Endex 303 prices from the Belgian Engie website
Hope this helps!
