How to convert AIXM 5.1 file to ESRI geodatabase or shapefile? What kind of Transformers I should use?

Hi @olex25​

Since AIXM is an XML based format, perhaps some of the XML Transformers would be relevant! You might get some additional tips from the AIXM 4.5. and 5.1 Reading, Writing, and Validating - EU Airports Demo tutorial.

On the geometry side, the GeometryExtractor might come in handy. There are a number of 'Extractor' type transformers that can help you extract things like bounds, center points, and more! Another great resource when working with Geodatabase is the Geodatabase Transformations tutorial as it goes over some of the basics of working with geodatabase.
