XML to base64 using python

How to convert complete xml file to base64 string using python/ scala?
I have tried b64 module ,but it requires a string(bytes-like) to be passed to it . But how to do that with ML given it's multiline structure and hierarchy.
Could anyone give an example on how to do it.
Thanks.

Python solution:
import base64
# convert file content to base64 encoded string
with open("input.xml", "rb") as file:
encoded = base64.encodebytes(file.read()).decode("utf-8")
# output base64 content
print(encoded)
decoded = base64.decodebytes(encoded.encode('utf-8'))
# write decoded base64 content to file
with open("output.xml", "wb") as file:
file.write(decoded)
# output decoded base64 content
print(decoded.decode('utf-8'))

How do I decompress a compressed base64 string?

The following is the string I want to decompress:

I have tried zlib:
import zlib
decompressed_data = zlib.decompress(data)
I get the following error:
TypeError: a bytes-like object is required, not 'str'
Then I did:
data = bytes(data, "utf-8")
decompressed_data = zlib.decompress(data)
I get an error again:
Error -3 while decompressing data: incorrect header check

You first need to decode the base64, then zlib decompress:
import zlib, base64
decompressed_data = zlib.decompress(base64.b64decode(data))
Looking at your data, it appears to be UTF-8 encoded XML, so we're almost there:
xml = decompressed_data.decode("utf-8")

How can I decode a json File using base64 decode?

I have a json file and I have to extract only the value of the key "data" and decode the base64-encoded.
This is the json file

But I got this error:

I have no idea how to resolve this error. I also tried using python but I couldn't decode it.

Considering that you have loaded the json data into an object. You can then try the following:

}
print(base64.b64decode(json_obj["data"]))

Here's a way to do that in Python:
import base64
import json
with open("sample_data.json") as f:
text = f.read()
d = json.loads(text)
data = base64.b64decode(d["data"])
The variable data now contains the decoded content of the relevant item in the json file.

If the string in .data were a valid base64 encoding of a UTF-8 string, the following would be equivalent:
jq -r .data input.json | base64 -D
and
jq -r '.data|#base64d' input.json
As it happens, with the given JSON, base64 shows there is a problem:
$ jq -r .data input.json | base64 -D
Invalid character in input stream.

How to backup database using XMLRPC?

I'm trying to backup my database using the following script:
import xmlrpclib
sock = xmlrpclib.ServerProxy('http://localhost:8069/xmlrpc/db')
backup_file = open('backup.dump', 'wb') # Same extension used by Odoo
backup_file.write(sock.dump('mypassword', 'mydb'))
backup_file.close()
At this point the content of the file is something like this:

When backing up through the Odoo Database Management I get a zipped file which is what I'm trying to achieve. For example test_2014-11-12_16-06-35Z.dump:
Is there a way to "reconstruct" all those bytes to a valid Odoo backup file? I tried with StringIO and ByteIO with no success. Any help will be much appreciated.
Solution
Thanks to #André I finally have a solution:
import base64
import xmlrpclib
sock = xmlrpclib.ServerProxy('http://localhost:8069/xmlrpc/db')
backup_file = open('backup.dump', 'wb')
backup_file.write(base64.b64decode(sock.dump('mypassword', 'mydb')))
backup_file.close()

The dump() function encodes the file in Base64 before returning it. You can decode it with the base64 command:
base64 -d [dump file] > [decoded file]

How to get the content of a remote file without a local temporary file with fabric

I want to get the content of a remote file with fabric, without creating a temporary file.

from StringIO import StringIO
from fabric.api import get
fd = StringIO()
get(remote_path, fd)
content=fd.getvalue()

With Python 3 (and fabric3), I get this fatal error when using io.StringIO: string argument expected, got 'bytes', apparently because Paramiko writes to the file-like object with bytes. So I switched to using io.BytesIO and it works:
from io import BytesIO
def _read_file(file_path, encoding='utf-8'):
io_obj = BytesIO()
get(file_path, io_obj)
return io_obj.getvalue().decode(encoding)

import tempfile
from fabric.api import get
with tempfile.TemporaryFile() as fd:
get(remote_path, fd)
fd.seek(0)
content=fd.read()
