RE: Updating instance data in XPL

Following my post earlier today about this, I'd like to add my vote for
a processor that will convert to base64 as well!

Thanks for the tip to the list. You got it, this is exactly the way to
do it. Of course you do not have to use oxf:xupdate, but you can also
use oxf:xslt, or in fact anything you want to produce the resulting XML
instance.

That's correct. The XML converter produces a text document, and the
To-XML converter converts from Base64, not to Base64.

There is org.orbeon.oxf.util.Base64.encode(byte[] binaryData) which you
may be able to call from XSLT, but we have not tried that.

I entered an RFE for this:

Not sure what the best way to go is!

Even better than vote would be to implement it and contribute it ;-)

A good start would be the ToXMLConverter class, which is quite simple,
and does something similar.

May well have a look at this -- not for a few weeks though due to time
pressures!  We definitely need it.
