It's easy. You got callback, where you can gobble up string buffers with incoming chars for element contents. ( and there is a lot of this stuff... ) After tag is closed, you have all the chars in a big string buffer, and get another callback - in this callback you have to convert data, and do whatever necessary ( in my case, create input stream, and pass it to database ) > > > 3.

My scenarios: - I'm exporting information as base64 to XML with help ov velocity. I do it through custom directive - in this directive I get a Writer from velocity, where I have to put my data. Ideally codec would do: read input stream - encode - put it into writer without allocating too much memory. I'm importing information: - I have stream ( string ) of base 64 data - codec gives me an input stream which is fed from this source and does not allocate too much memory and behaves polite... regards, ===== ----[ Konstantin Pribluda ( ko5tik ) ]---------------- Zu Verstärkung meines Teams suche ich ab Sofort einen Softwareentwickler[In] für die Festanstellung.
