Hi,

I was tying out to see if it is possible to send binary information(like an .jpeg file or .ppt file) embedded in an xml.
I was trying to have the file name and some more details in the xml and one of the tags in the xml would be the binary file itself. Is it possible to do this? The xml file so created will be moved from one location to another using SFTP. In the receiving location, I will have to store the file as it is - after extracting it(if required).

Any better suggestions on this are welcome.

Thanks,
Anoop

Encode it with base64!

Henry, your solution is 6 times less efficient than base64 in terms of space usage, you have 1 character/bit vs. 1 char/6bits, as with base64!

Thanks for the suggestion.
I was trying out some text which was encoded and decoded using base64 and it seems to work fine. Wanted to know if this is ok to be used for .jpeg files and if there are any chances for the image to be corrupted when decoding. I came to know that base64 uses only a-z, A-Z, 0-9, + and / but wanted to know if it is safe to use this in an xml.

Base64 would be pretty useless if it didn't decode back to the original, wouldn't it?

XML would be pretty useless if it couldn't contain all of those characters, wouldn't it?
 
Don't get me started about those stupid light bulbs.
