I have been puzzling for a while how to process data available on the Dutch portal www.pdok.nl

After downloading a gml-file (type Dutch TOP 10 GML), I would like to extract the information stored in elements and convert this information into attributes.

Therefore I use the XMLQueryExtractor. This does the job, information is temporarily stored in lists but this is a very timeconsuming process. Examples of elements with multiple values from the featuretype ‘Wegdeel’ are naam, typeWeg ,hoofdverkeersgebruik and fysiekVoorkomen.  Is there a more efficient method?

 

I have attatched an example workspace…

 

Many thanks in advance.

Hi @pzwaag_wf​ 

I don't believe it's necessary to XMLXQueryExtractor to store the attribute values in a list and then parse out the values again.

The attribute values are stored in lists, which are not automatically exposed on features. Simply use the AttributeExposer to expose the attributes. I have attached an example of this workflow. I hope this helps.
