Hi i want send via socket xml like this.
<root>
<image ID='2'>
<![CDATA[ binary data with image ]]>
</image>
</root>
I have problem because image is binary data and other part is string. I am sending multiple images and i need to have ID.
The main problem is what to do with binary data and string data. I tried to convert image to str but i cant revert this.
A useful way to embed binary in xml is base64-encoding it. This is the approach XAML uses to send small images for example. You may do like this somewhere in your code:
import base64
img = open('some.png',rb').read()
base64.b64encode(img)
# append it to your buffer
And on the other side:
#get the img portion in the buffer
import base64
img = base64.b64decode(fetched_img)
# write it to disk or whatever
This is the standard/usual way to treat binary files inside XML.
Using base64 is very simple, this is a example in the interpreter:
In [1]: import base64
In [4]: base64.b64encode('example')
Out[4]: 'ZXhhbXBsZQ=='
In [5]: base64.b64decode('ZXhhbXBsZQ==')
Out[5]: 'example'
You can read the docs here.
Hope this helps!
CDATA[ ... ] there should be only the b64encoded file so this line: stringResult = base64.b64decode(stringResult) + base64.b64encode(f.read()) should be like this I guess: stringResult = base64.b64encode(f.read()). I don't see where you decode it though. Somewhere in the receiver, should be: img_str=CDATA (pseudocode here), img = base64.b64decode(img_str) to get the binaries into img
b64encode something and it returns a string. Then you b64decode it and get what you first encoded back..pdf file. I don't know what your problem might be. You maybe want to open a new different question about your new problem.Just connect the socket as binary - it is anyway and you probably don't care about newline conversion anyway.
