XML 到 base64 使用 python

Question

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'))
