Extract zip to memory, parse contents

Question

I want to read the contents of a zip file into memory rather than extracting them to disc, find a particular file in the archive, open the file and extract a line from it.

Can a StringIO instance be opened and parsed? Suggestions? Thanks in advance.

zfile = ZipFile('name.zip', 'r')

    for name in zfile.namelist():
        if fnmatch.fnmatch(name, '*_readme.xml'):
            name = StringIO.StringIO()
            print name # prints StringIO instances
            open(name, 'r')  # IO Error: No such file or directory...

I found a few similar posts, but none that seem to address this issue: Extracting a zipfile to memory?

Answer 1

Thank you to everyone that contributed solutions. This is what ended up working for me:

zfile = ZipFile('name.zip', 'r')

        for name in zfile.namelist():
            if fnmatch.fnmatch(name, '*_readme.xml'):
                zopen = zfile.open(name)
                for line in zopen:
                    if re.match('(.*)<foo>(.*)</foo>(.*)', line):
                        print line
