[xml] Streaming API for xml writing?

["Yong Chen (yongche)" <chen cisco com>]

Hi,

I know there's a streaming API for reading xml doc (xmlTextReader). I
wonder if there's a streaming API for writing?

Basically what I want to do is to write out xml doc when it's still
being built. This is to handle the situation that the final xml doc may
be too big to fit in memory (before it's written out).

Is xmlTextWriter the API for it? Is there any example/tutorial for it?

Thanks,
