I noticed a new problem while analyzing some websites.
In the first step I need to collect again all jobresults from a list. But how can I analyze the text of the singular vacancies when the links to the sites are always "javascript:voidFunction();"??
I assume the JavaScript on the mentioned link triggers any functionality which either loads a new page or changes/replaces the current page's content? That's exactly what the Selenium nodes are made for, you can act with your KNIME workflow like a person would interact with a browser. So, simply apply a "Click" node to perform the action and then apply whatever extraction/interaction logic you want to do.
"Find Elements" will extract any match, so if you extract multiple results, you might want to use the loop nodes, to perform your interaction step wise for each found result.
