Is MSXML4 thread safe?

Question

I would like to know if I create an instance of Msxml2.FreeThreadedDOMDocument.4.0 in one thread, can I safely manipulate the instance from different threads using raw pointers?

Answer 1

Yes. That is the point of the FreeThreadedDOMDocument.

If you are writing a single threaded application (or a multi-threaded application where only one thread accesses a DOM at one time), then you should use the rental threaded model (Msxml2.DOMDocument.3.0, Msxml2.DOMDocument.4.0, or Msxml2.DOMDocument.6.0). If you are writing an application where multiple threads access will simultaneously access a DOM, then you should use the free threaded model (Msxml2.FreeThreadedDOMDocument.3.0, Msxml2.FreeThreadedDOMDocument.4.0, or Msxml2.FreeThreadedDOMDocument.6.0).
