Hey Simon,
with the Selenium Nodes, you can check the option "Append additional WebElement information", which will give you a dedicated column with the extracted node names. You can use the same XPath query //* to get all elements on the page. However, the elements will be extracted row-wise (i.e. for each found element, a row is created). I guess it should be easy to transform that into a column-based table.
Hope I understood your issue correctly. In case you have any improvement suggestions, feel free to get in touch (forum or email).
Best,
Philipp
