It was possible to read and write .gml (geography markup language) files in Alteryx. From 2018.2 and up, only write is supported. I do not understand why such a feature was removed, considering that this has become one of the standard geoformats. Joining data from .gml and .shp files is one of the key activities when dealing with geodata. Now I have to spend time converting the files (e.g. in QGIS or ArcGis). FME can read/write .gml just fine, so why can't Alteryx?
