Normally the web request control seems to be a great enrichment in Nintex forms. However the problem I see that it is obviously not possible to concat the display data in xpath. Is there any possibility? I could not use any function which worked (for example the concat function or the |). In the display it would be much better to have more informations. 

Another big problem I see is that it seems not to be possible to avoid duplicates. For example in my example in the subset of an organisation there can be twice an address which leads to duplicates in town. I am only interested in the first subset (address). 

Does somebody know a workaround, e. g. with a calculated control. If possible I would like to avoid a workflow...

Thank you in advance for every input!
