XMLBase64 into cdata section

[Mike Ellery <mi...@s2technologies.com>]

I'm encoding some data using Base64::encode, which returns me XMLByte*. 
  Now I want to create a CDATA section using the encoded bytes - the 
document's createCDATASection method takes XMLCh*.  How do I get to here 
from there?  Do I need to use XMLString::transcode to get XMLCh?

Apologies if this is covered in the docs - I couldn't find it.

You could use a UTF-8 transcoder, but since the data is guaranteed to be 
ASCII-only, you could simply copy each code unit:

unsigned int outputLength = 0;

const XMLByte* const bytes =
         Base64::encode(
             bytesIn,
             bytesInLength,
             &outputLength);

XMLCh* wideChars = new XMLCh [outputLength + 1];

for (unsigned int i = 0; i < outputLength; ++i)
{
    wideChars[i] = bytes[i];
}

XMLString::release(&bytes);

wideChars[outputLength] = 0;

doc->createCDATASection(wideChars);

delete wideChars;
