Has anyone exported Metadata using a custom XSLT?

[cordtsra]

I am on Pro version 3.2.0. I am currently working on exporting feature class level metadata to xml files using a custom XSLT. I am currently getting the following error

 RuntimeError: Failed to export metadata to 's'
 File "C:\Program Files\ArcGIS\Pro\Resources\ArcPy\arcpy\utils.py", line 191, in fn_
    return fn(*args, **kw)
  File "C:\Program Files\ArcGIS\Pro\Resources\ArcPy\arcpy\metadata.py", line 144, in exportMetadata
    return _convertArcObjectToPythonObject(arcgisscripting.metadata.Metadata.exportMetadata(*_gp_fixargs((self, outputPath, metadata_export_option, metadata_removal_option, customStylesheetPath), True)))
  File "C:\Program Files\ArcGIS\Pro\Resources\ArcPy\arcpy\arcobjects\arcobjectconversion.py", line 67, in convertArcObjectToPythonObject
    name=type(obj).__name__
SystemError: <class 'type'> returned a result with an error set

My code is attached below.

xslt = r'C:/Documents/Custom.xslt'
if os.path.isfile(xslt):
    arcpy.AddMessage("xslt located")
else:
    arcpy.AddError("xslt file does not exist")

for fc, fcpath in FCtoFCPath.items():
    fcToExport=md.Metadata(fcpath)
    fcToExport.exportMetadata(os.path.join(mdir, fc + ".xml"), 'CUSTOM', 'EXACT_COPY', xslt)

If I change the last line of my code to

fcToExport.exportMetadata(os.path.join(mdir, fc + ".xml"), 'FGDC_CSDGM', 'EXACT_COPY')

The script executes without error, but it is not in the format that I need. Has anyone else had this error before, or know what might be causing the error?

Hi! We're also a bit mystified by the format conversion outputs from/into ESRI and aiming to develop our own XSLTs for a migration. I'm not sure if this helps you at all, but our developer has been looking into reusing some of the Geoportal Server Catalog (https://github.com/Esri/geoportal-server-catalog/tree/master/geoportal/src/main/resources/metadata/x...) and Harvester (https://github.com/Esri/geoportal-server-harvester/tree/master/geoportal-commons/geoportal-commons-m...) packaged XSLTs. As an open source project adjacent to ESRI, I believe that folks in the community have been developing support to export ESRI into other ISO profiles, including the European INSPIRE and UK GEMINI initiatives. Not sure how much they support feature-level metadata export, but I think it's worth looking into how these folks are doing it.

Hi did you ever find a solution to this problem? I'm trying to do a custom xslt transform and getting the same  error "SystemError: <class 'type'> returned a result with an error set"
