Script to print all data layer names and sources?

[847396730]

Hello! In a couple of Esri's python tutorials, they reference the capability of generating a printed document which lists all the data layers in an individual mxd, along with the source of those layers. I would like to do this, but can't find any sample script for it online. Thoughts? Thank you!

I'm not sure about printing (can't test here), but this will list the data source of each layer (help here) in a mxd (you can just as easily print the layer name):

import arcpy

mxd = arcpy.mapping.MapDocument("MXD PATH HERE")
layers = arcpy.mapping.ListLayers(mxd)

for layer in layers:
    if layer.supports("dataSource"): # some layers might not support the property "dataSource"
        print layer.dataSource

Thanks Darren! This worked on my first try for me. WOOO!

Using Darren's code above, simply write each layer.dataSource to a text file for printing like so:

import arcpy

doc = open("doc.txt", "a")

mxd = arcpy.mapping.MapDocument("MXD PATH HERE")
layers = arcpy.mapping.ListLayers(mxd)

for layer in layers:
    if layer.supports("dataSource"): # some layers might not support the property "dataSource"
        print layer.dataSource
        doc.write(layer.dataSource+"\n")

Thank you; this is perfect!

Using Darren's code above, simply write each layer.dataSource to a text file for printing like so:

import arcpy

doc = open("doc.txt", "a")

mxd = arcpy.mapping.MapDocument("MXD PATH HERE")
layers = arcpy.mapping.ListLayers(mxd)

for layer in layers:
    if layer.supports("dataSource"): # some layers might not support the property "dataSource"
        print layer.dataSource
        doc.write(layer.dataSource+"\n")

Is it possible for the script to:
a) write this output in a delimited format (the txt is undelimitable, if that's a word, due to the many backslashes in all the path names)
b) create the txt, instead of pouring into an existing txt file

Thanks again!

This code will create and write to a new csv file. Unfortunately, it delimits every character, and I haven't figured out how to fix that. If you do, please post how.

import arcpy, csv

mxd = arcpy.mapping.MapDocument("YOUR MXD HERE")
layers = arcpy.mapping.ListLayers(mxd)
filepath = "NEW CSV FILE PATH HERE"
writer = csv.writer(file(filepath, 'w'))

for layer in layers:
    if layer.supports("dataSource"):
        writer.writerow(layer.dataSource)
del writer

EDIT: this works

import arcpy, csv

mxd = arcpy.mapping.MapDocument("YOUR MXD HERE")
layers = arcpy.mapping.ListLayers(mxd)
filepath = "NEW CSV FILE PATH HERE"
writer = csv.writer(file(filepath, 'wb'))
sourcelist = []

for layer in layers:
    if layer.supports("dataSource"):
        sourcelist.append(layer.dataSource)
writer.writerow(sourcelist)
del writer

Hello! I keep getting this error with the second script: Runtime error <type 'exceptions.IOError'>: [Errno 22] invalid mode ('wb') or filename: ' F:\\MLF\\Special Projects\\District_Maps'

What am I doing wrong?  Thank you!

To clarify: this is the code I entered:

import arcpy, csv
mxd = arcpy.mapping.MapDocument("CURRENT")
layers = arcpy.mapping.ListLayers(mxd)
filepath = " F:\MLF\Special Projects\District_Maps"
writer = csv.writer(file(filepath, 'wb'))
sourcelist = []
for layer in layers:
    if layer.supports("dataSource"):
        sourcelist.append(layer.dataSource)
writer.writerow(sourcelist)
del writer

Try taking out the space before your filename. Other than that, I think the 'wb' option might depend on your version of python, and possibly operating system. I'm using 2.6.5 on Windows 2008, but actually I was going off examples from 2.7. I see posts from 2.6 users who say to use 'w', so maybe try that.

I am looking for a way to list all .mxd files in a directory "P:\data\" that have certain .shp file data layer in them.  I have about 1400 .mxd files in my "P:\data\many subfolders\many subfolders".  I would like to find which of the 1400 .mxd files have a special.shp file data layer in the .mxd file.  I need to know which .mxd files have the special.shp data layer in the whole directory.  Can this be done and can someone please help me.
