Hi mr Bray,

You may have already considered this but this came into my mind yesterday:

Expat's isFinal feature (the parameter to XML_Parse etc.) allows us to parse
in chunks, you can send it "<node>" and on the next call "text" and then 
"</node>" etc.
This feature makes writing very pedantic (as pedantic as expat) 
well-formedness writer
quite easy. I believe there could even be validity checker attached if one 
has such
a thing on top of expat!

I wrote little program demonstrating this, it's called naxWriter which 
means "natural
xml writer" i.e. you can feed "natural" xml to it; it checks 
well-formedness using
expat's XML_Parse and if expat thinks it's ok, it output xml as you wrote 
it! (You only got yourself
to blame for pretty printing flaws ;-) )

Of course one could write StartElement type of constructs with &lt; 
escaping etc. on top of this.

The source is attached, you only have to link it with -lexpat or 
libexpat.lib in win
if you want to test it.

I guess there's still need for standalone genx implementation, I don't know
if this kind of writer is any good in real world  ;-)



with respect,
Toni Uusitalo
