[xsd-users] Re: Never failing in Parsing

[Boris Kolpackov]

Hi,

I see you have figured out how to serialize the object model back
to XML. In the future, please don't send multiple emails asking
essentially the same question. One is enough and someone will reply
when/if they have time. If you need more predictable assistance, I
suggest you consider purchasing a Priority Support contract:

You mean serializer, not parser? Your code below doesn't perform
any parsing, only serialization.

The C++/Tree mapping doesn't support automatic XML Schema validation 
during serialization. What you can do, however, is re-parse the XML
to make sure it is valid. So given the code above, you can add:

try
{
  std::istringstream iss (xml);
  nt_(iss, "<in-memory-xml>");
}
catch (const xml_schema::exception& e)
{
  std::cerr << e << std::endl;
}
