How I can store base64 strings in XML?
Do you use CDATA to store base64 strings in XML? Would it help as it allows use of < > within the strings?
Is base64 configurable where you tell it not to use certain chars if they conflict with XML?

There are no characters whatsoever in the Base64 charset that will conflict.
No need to encode anything for XML.
Base64 only uses alphanumeric characters and '+' (plus), '/' (slash) and '=' (equals).

Is it possible to use a RegEx to validate, or sanitize Base64 data? That's the simple question, but the factors that drive this question are what make it difficult.
I have a Base64 parser that can not fully RELY on the input data to follow the RFC specs...

From the RFC 4648 :
Base encoding of data is used in many situations to store or transfer data in environments that, perhaps for legacy reasons, are restricted to US-ASCII data.

TouchCode has http://touchcode.googlecode.com/hg/Support/Common/Base64Transcoder.c (and .h)
There is also some quite simple code you can use here:

Another interesting way to do it, using OpenSSL:

I have an image that is base64 encoded. What is the best way to decode that in Java? Hopefully using only the libraries included with Sun Java 6.

Example....
You can import at javax.mail.internet.MimeUtility.decode().
Commons codec
Specifically in Commons Codec: class Base64 to decode(byte[] array) or encode(byte[] array)
No need to use commons--Sun ships a base64 encoder with Java.

The JSON format natively doesn't support binary data. The binary data has to be escaped so that it can be places into a string element (i.e. zero or more Unicode chars in double quotes using backslash escapes) in JSON.
An obvious method to escape binary...

YEnc might work for you:

Can you compress the binary data first, before encoding?
Since you're looking for the ability to shoehorn binary data into a strictly text-based and very limited format, I think....

It is possible to base64 encode an image and deliver it as part of the html content using the <img src="data:image/gif;base64,UEsDBBQAAAgIALp9...MTs9Snj3==">

Even if you were to get it to work, I recommend against that approroach for the following reasons:

I have seen several questions on how to encode an image file in base64, but how about the other way around - how do I reconstitute a picture from a base64 string stored in an XML file?

I need to find a way to find a way to find the hash for the base64 encoded data in the XML node //note/resource/data , or somehow otherwise match it to the hash value in the node //note/content/en-note//en-media@hash
See below for the full XML file

Download some freeware Base64 decoder like this one or use some source code from the web that this hash was created using MD5 on the GIF file.
