Hi Carl,
I think the best approach for either language is to use an
implementation that prepares queries. The two languages are not terribly
different in the way they handle conditions on headers.
I think that reading the content of the message is the slowest part of
the XML Exchange, I've roughed in code that should allow me to avoid
that for queries that do not actually access the message. (If the
exchange could access the message content as an istream, the query
engine would do this for me; as is, I have to check this by hand).
Boost provides convenience libraries that making implementing istream fairly
easy. It shouldn't be hard to write an istream impl that iterates over message
content. Take a look at
