The following script is supposed to find and replace all shapefiles in a mxd (that exist in the folder) to the new SDE data source. No errors when running the script however, when I open the MXD in ArcGIS 10.1SP1 nothing changed. Any suggestions what is wrong?

import arcpy, os, glob

#find all the MXD's in the directory tree
for root, subFolders, files in os.walk(r"C:\Users\lmuhammad\Documents\ArcGIS\SearchandReplace\Testing"):
for filename in files:
    fullpath = os.path.join(root, filename)
    basename, extension = os.path.splitext(fullpath)
    if extension.lower() == ".mxd":
        print "------------------------------"
        print filename
        #open the map document
        MXD = arcpy.mapping.MapDocument(fullpath)
        #get all the layers
        for lyr in arcpy.mapping.ListLayers(MXD):
            #get the source from the layer
            if lyr.supports("datasource"):
                source = r"R:\Shapefiles\Road_Casings\RoadCasing.shp"
                print "%s -> %s" % (lyr, source)
                basename, extension = os.path.splitext(source)
                if extension.lower() == ".sde":
                    #This is the NEW SOURCE that you want to point to
                    datapath = r"Database Connections\Connection to GISD.sde\GISDEV.TRANSPORTATION\GISDEV.PAVEMENTEDGE"
                    #replace the old path wih the new
                    lyr.findAndReplaceDatasource(source, datapath, "NEWROAD", False)
        #save your changes
        MXD.saveACopy(r"C:\Users\lmuhammad\Documents\ArcGIS\SearchandReplace\Testing\test2.mxd")
        del MXD

It is obvious that the code is not going to do what you want as it is currently structured. Did you just copy and paste it from somewhere? –  blah238 Feb 4 '13 at 16:50
    
Yes I copied and paste it.. no one at ESRI Support or on GIS forums seem to know how to do a basic search and replace of datasources - from a shapefile to a sde_connection with multiple datasets & feature class for multiple mxds in a folder. –  user14690 Feb 5 '13 at 20:00
    
Where did you find the original script? –  blah238 Feb 5 '13 at 21:27

I found it here - sspinnovations.com/blog/2012/05/07/… –  user14690 Feb 6 '13 at 20:19
    
It works for feature classes that are in the same dataset..but not for different datasets. –  user14690 Feb 6 '13 at 20:19

I would recommend breaking this up into two functions:

  1. A function to replace the data sources in one MXD
  2. A function that calls the previous function on each MXD in a directory tree

You'll want to test the first function thoroughly by itself before moving on to the second.

I recommend using a Python IDE such as PyScripter to develop, test and debug your scripts.

Please try to work at this yourself and if you run into a wall, edit your question to include the pertinent information such as what you tried (including code!), what you expected to happen, and what error messages or unexpected output you got.
