[GIS] AttributeError: ‘unicode’ object has no attribute ‘_arc_object’ from arcpy.mapping.ListLayers

I'm trying to write a script that allows me to list .mxd files in a folder and then list the layers in each map document, however, I keep getting this error:

Traceback (most recent call last): File

AttributeError: 'unicode' object has no attribute '_arc_object'

This is the code I am using :

import arcpy
import os

PATH2 = r"C:\Users\Daimon Nurse\Desktop\DFMPROJECT"
arcpy.env.workspace = PATH2
arcpy.env.overwriteOutput=True

for file in arcpy.ListFiles("*.mxd"):
    lyr = arcpy.mapping.ListLayers(file)
    print file

Best Answer

Try converting "file" to a full pathname, then opening the doc with mapping.MapDocument, like this:

for file in arcpy.ListFiles("*.mxd"):
    filePath = os.path.join(PATH2,file)
    print filePath
    MapDoc = arcpy.mapping.MapDocument(filePath)
    lyrList = arcpy.mapping.ListLayers(MapDoc)
    for Lyr in lyrList:
        print Lyr
