Write GML to multiple ZIP files

...and perhaps I should say there is also a little extra complexity in that I am currently using the file copy writer to also copy a couple of standard supporting files across into each zip file. So if this ends up as a Shutdown Script solution I'll also need to have scope to add some common files into the zip too!

Hi Dave and David,

 

 

Last year, I also found the Dataset Fanout does not support zip compressing, and sent a question to Safe support. Unfortunately the current FME doesn't support fanout with zip.

 

 

The Workbench help says: "Note: You cannot create multiple zip files using Dataset Fanout (therefore, you cannot set the Fanout Suffix parameter to .zip)."

 

-- FME Workbench > Readers and Writers > Readers and Writers: Zip Files and URLs > Writing to a Zip File

 

 

This is an example for writing zip files in Shutdown Python Script.

#Shutdown Python Script Example

 

import fme, os, zipfile

 

 

# You will have to define these two lists appropriately.

 

baseNames = ['North', 'South', 'East', 'West']

 

commonFiles = ['C:\\\\Data\\\\common1.txt', 'C:\\\\Data\\\\common2.txt']

 

 

# Get GML and ZIP folder paths from published parameters.

 

gmlDir = fme.macroValues['DestDataset_GML']

 

zipDir = fme.macroValues['ZIP_ROOT_FOLDER']

 

 

# If the ZIP folder doesn't exist, create it.

 

if not os.path.exists(zipDir):

 

    os.makedirs(zipDir)

 

 

try:

 

    for name in baseNames:

 

        # GML file path

 

        gmlPath = '%s\\\\%s.gml' % (gmlDir, name)

 

        if not os.path.exists(gmlPath):

 

            # If the GML file doesn't exist, what should I do?

 

            continue

 

        

 

        # ZIP file path

 

        zipPath = '%s\\\\%s.zip' % (zipDir, name)

 

        

 

        # Write the GML file into a new ZIP file.

 

        z = zipfile.ZipFile(zipPath, 'w', zipfile.ZIP_DEFLATED)

 

        z.write(gmlPath, '%s.gml' % name)

 

        z.close()

 

        

 

        # Append the common files into the ZIP file.

 

        z = zipfile.ZipFile(zipPath, 'a', zipfile.ZIP_DEFLATED)

 

        for common in commonFiles:

 

            z.write(common, os.path.basename(common))

 

        z.close()

 

except Exception as ex:

 

    # Do something if necessary.

 

    pass

 

finally:

 

    # Do something if necessary.

 

    pass

Hope this helps.
