How to filter the list of loaded & orphaned & not found xref by their status from all file references using dynamo

Is there any dynamo script or python code which can filter the loaded & orphaned & not found xrefs by their status from all file references through dynamo and make a separate list.

While I couldn’t find a node in Dynamo (haven’t looked in 2025 yet) you may look at the GetHostDwgXrefGraph method in a Python node. I managed to get all loaded xrefs including attached xrefs where the results are listed as lists, if a list is longer than 1 the next xrefs are attached xrefs. unloaded xrefs are ignored. It is a fairly untested script so no idea how well it works.

# Load the Python Standard and DesignScript Libraries

# Add Assemblies for AutoCAD and Civil3D
clr.AddReference('AcMgd')
clr.AddReference('AcCoreMgd')
clr.AddReference('AcDbMgd')
clr.AddReference('AecBaseMgd')
clr.AddReference('AecPropDataMgd')
clr.AddReference('AeccDbMgd')

# Assign your output to the OUT variable.
