I'm writing a script that will run through multiple mxd files and list the file name, and then the layer names, data sources, and fields. The script runs fine when I run it in the Python window or if I run the script tool in ArcMap while the mxd is open, but if I refer to a different mxd or just run the script in ArcCatalog, it gives IO Errors and says that it can't find the layers. Here's my code:import arcpy
#set file path for input mxd
fileName = arcpy.GetParameterAsText(0)
arcpy.AddMessage("got file name: " + fileName)
fileNameList = fileName.split(";")
#set file path for output txt file
out = open(arcpy.GetParameterAsText(1), "w")
arcpy.AddMessage("got out file")
#loop through file names
for fName in fileNameList:
mxd = arcpy.mapping.MapDocument(fName)
arcpy.AddMessage("got map file: " + mxd.filePath)
#print mxd file name
out.write("Mxd file: " + mxd.filePath + '\n')
#print list of data frames
for df in arcpy.mapping.ListDataFrames(mxd):
out.write("Data Frame:" + '\n')
out.write(df.name + '\n')
out.write("Layers:" + '\n')
for lyr in arcpy.mapping.ListLayers(mxd, "*", df):
out.write(lyr.name + '\n')
try:
if lyr.supports("DATASOURCE"):
out.write(lyr.dataSource + '\n')
if lyr.isGroupLayer == False:
fieldList = arcpy.ListFields(lyr)
for field in fieldList:
out.write(str(field.name) + ", ")
out.write ('\n')
except Exception as e:
out.write("field error" + '\n')
out.write(e.message + '\n')
out.write(str(type(e)) + '\n')
out.write('\n')
del mxd
#close output file
out.close()
Any help would be greatly appreciated!
