Search MXDs with specific dataSource layer using Python

Question

I work with ArcGIS 10.3 and I try to search a specific layer (with dataSource named "D:\desktop\Project\layers1円.jpg" ) in hundred of mxd's that spread in folder "D:\PROJECTS" and it divided to hundred of sub folders, using python 2.7.8:

import arcpy,os,sys
import arcpy.mapping
from arcpy import env
env.workspace = r"D:\PROJECTS"
for mxdname in arcpy.ListFiles("*.mxd"): 
 mxd = arcpy.mapping.MapDocument(r"D:\desktop\Project\\" + mxdname)
 dfList = arcpy.mapping.ListDataFrames(mxd, "*")
 for df in dfList:
 for lyr in arcpy.mapping.ListLayers(mxd, "", df):
 if lyr.isGroupLayer == True: continue 
 if lyr.dataSource == r"D:\desktop\Project\layers1円.jpg":
 print mxdname, mxdname.pathway
 mxd.save()
del mxd

Finally, I want that python will print all the mxd's source name that contain the specific layer I search for. When I run the code I get error:

project1.mxd
Traceback (most recent call last):
 File "C:\Users\yaron.KAYAMOT\Desktop\idle.pyw", line 13, in <module>
 print mxdname, mxdname.pathway
AttributeError: 'unicode' object has no attribute 'pathway'

Answer 1

From the listfiles docs:

Returns a list of files in the current workspace based on a query string

So mxdname does not have a pathway attribute. It's simply a string of the mxd name.

Answer 2

Finally, i used this code:

import arcpy 
from arcpy import mapping as m 
from os import path, walk 
root_directory = r"D:\PROJECTS" 
path_to_find = r"F:\GIS\topo_5000050000円.sid" 
def FindMaps(root_directory, path_to_find):
maps = [] 
for root, dirnames, filenames in walk(root_directory): 
 for fname in [f for f in filenames if f.endswith(".mxd")]: 
 mxdPath = path.join(root, fname) 
 if not path.isfile(mxdPath): 
 continue 
 mxd = m.MapDocument(mxdPath)
 df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0]
 for df in m.ListDataFrames(mxd): 
 for lyr in m.ListLayers(mxd, data_frame=df): 
 if lyr.supports("DATASOURCE"): 
 if lyr.dataSource == path_to_find: 
 print(mxdPath) 
 maps.append(mxdPath) 
 break 
return maps
FindMaps(root_directory, path_to_find)
