Suggest using the forward slash instead of the backslash, i.e. instead of path = r"I:\ARC\DATA\MXDs" use path = r"I:/ARC/DATA/MXDs"

 

Python should interpret that correctly when it comes to file names.   Backslash is an escape character.   If you want to use backslash it needs to be repeated, like this:  path = r"I:\\ARC\\DATA\\MXDs"

 

 

 

Would anyone mind taking a look at this Python code and telling me why it says my MXD filename is invalid?

 

import arcpy, os

 

path = r"I:\ARC\DATA\MXDs"

 

for root, dirs, files in os.walk(path):

    for fileName in files:

        fullPath = os.path.join(path, fileName)

        basename, extension = os.path.splitext(fullPath)

        mxd = arcpy.mapping.MapDocument(fullPath)

        if extension == ".mxd":           

            for df in arcpy.mapping.ListDataFrames(mxd):

                for lyr in arcpy.mapping.ListLayers(mxd,"",df):

                    findthis = value1

                    findthat = value2

                    if findthis in lyr.name or findthat in lyr.name:

                        lyr.replaceDataSource(r'I:/ARC/Data/ITrees.gdb','FILEGDB_WORKSPACE','Trees')

                        print(lyr.name + " - Layer Resourced")

                    else:

                        pass

                        print lyr.name + ": Pass"

                    arcpy.RefreshTOC()

                    arcpy.RefreshActiveView()

                    mxd.save()

print "--Script complete--"

Results:

 

Traceback (most recent call last):

  File "I:\ARC\Data\Expressions\Trees_Walk.py", line 9, in <module>

    mxd = arcpy.mapping.MapDocument(fullPath)

  File "C:\Program Files (x86)\ArcGIS\Desktop10.1\arcpy\arcpy\arcobjects\mixins.py", line 609, in __init__

    assert (os.path.isfile(mxd) or (mxd.lower() == "current")), gp.getIDMessage(89004, "Invalid MXD filename")

AssertionError: Invalid MXD filename.

 

 

 

When I print the variable “fullPath” it looks something like this:

 

I:\ARC\DATA\MXDs\Clinton Base Map.mxd

 

But when I feed the value  into

 

mxd = arcpy.mapping.MapDocument(fullPath)

 

it doesn’t like it anymore

 

 

Kind regards,
