Triple zipped XML

Hi Itay, current FME seems not to have the capability to unzip recursively.

 

This example is from my old PythonCaller implementation. FYI.

import fmeobjects

 

import os, re, zipfile

 

 

class RecursiveUnzipper(object):

 

    def input(self, feature):

 

        def clearDirectory(path):

 

            if os.path.isdir(path):

 

                for t in ['%s/%s' % (path, s) for s in os.listdir(path)]:

 

                    clearDirectory(t)

 

                os.rmdir(path)

 

            else:

 

                os.remove(path)

 

                

 

        # Get zip file path and destinction directory path.

 

        zipPath = feature.getAttribute('_zip')

 

        outDir = feature.getAttribute('_out_dir')

 

        if os.path.exists(zipPath):

 

            # If specifid output directory exists, remove it beforehand.

 

            if os.path.exists(outDir):

 

                clearDirectory(outDir)

 

            self.index = 0

 

            self.unzip(feature, zipPath, outDir)

 

        self.pyoutput(feature)

 

        

 

    # Unzip recursively

 

    # Extracted file paths will be stored in a list called "_unzipped{}".

 

    def unzip(self, feature, path, outDir = None):

 

        if os.path.isfile(path):

 

            m = re.match(r'^(.+)\\.zip$', path, re.IGNORECASE)

 

            if m != None:

 

                zip = zipfile.ZipFile(path)

 

                if zip.testzip() == None:

 

                    dir = outDir if outDir else m.group(1)

 

                    zip.extractall(dir)

 

                    for t in ['%s/%s' % (dir, s) for s in os.listdir(dir)]:

 

                        self.unzip(feature, t)

 

            else:

 

                feature.setAttribute('_unzipped{%d}' % self.index, path)

 

                self.index += 1

 

        elif os.path.isdir(path):

 

            for t in ['%s/%s' % (path, s) for s in os.listdir(path)]:

 

                self.unzip(feature, t)
