Re: [Simple-support] Streaming root elements

[Niall G. <gal...@ya...>]

Hi,

This is caused by StAX rather than Simple. There may be a StAX implementation that does not use a buffering input stream out there, perhaps the Woodstox StAX implementation? Also you could create a single root and write all nodes as children of that root. If none of these are satisfactory then you will have to wrap the input stream in something that will give all bytes up to the final element. I might add this to the org.simpleframework.xml.util package myself as others have asked the same.

Regards,
Niall
