If it's a requirement that "xmlChar *" be valid null-terminated utf8, then I'd agree it seems this is PHP's responsibility. Are there perhaps other places where this needs to be checked besides just with xmlTextWriterWriteAttribute()? On Tue, Jan 25, 2011 at 05:45:48PM +0100, Pierre Joye wrote:
Btw, I re opened the php one as Daniel seems to think that it is the application responsibility and not libxml. I'm not totally convinced and I asked Rob to check this problem again.
