Jonathan Robie updated QPID-879:
--------------------------------
Attachment: xmlexchange.diff
This patch implements an XML Exchange using XQilla and Xerces (configure.ac is
set up to ensure that the XML Exchange is built only if the libraries are
available on the given system).
A new exchange type, "xml", is available. The following code shows how to bind
a query on this exchange:
session.queueDeclare(arg::queue="message_queue");
session.exchangeDeclare(arg::exchange="xml", arg::type="xml");
FieldTable binding;
binding.setString("xquery", "declare variable $control external;"
"./message/id mod 2 = 1 or $control = 'end'");
session.queueBind(arg::exchange="xml", arg::queue="message_queue",
arg::routingKey="query_name", arg::arguments=binding);
The language used to specify bindings is XQuery. Query conditions can be set on
message properties using external variables, or on the content of an XML
message using path expressions, or both.

> I am writing a new exchange type for XML content. Bindings for the XML
> exchange type can specify binding conditions using XQuery.
> I'm implementing this using the XQilla engine
