How do I bring repeating tags from an XML file into a single table cell?

In my xml file, which I want to bring into a table, there are recurring tags under the same parent tag. So these values should be in the same table cell.

But how can I do this? All the options in the XPath node puts the contents in separate rows or columns.

If I want to have the values in a cell, the values of the next parent tags with the same name also go into this cell. So how does that work?
