As of build 2.8-alpha b367, you can now import data from XML files using your own point-and-click custom definition to convert the (tabular) XML data into a tabular dataset.

1. Add in an XML file using the 'Data file' source and choose 'Definition' as the transform type
2. Edit the definition and using the table, select the tags/attributes to import into the dataset.
3. Choose the tag/attribute ('Record item') which will identify dataset records in the XML data

Additional options include the default labelling format for the dataset fields and previews of the XML and dataset.
