class IFastXmlCallback

Remarks

Create your own class that implements the IFastXmlCallback interface to process the XML elements as they are loaded by FFastXml::ParseXmlFile(). You'll receive a ProcessElement() call for every XML element that is encountered, along with a corresponding ProcessClose() when that element's scope has ended. ProcessAttribute() will be called for any attributes found within the scope of the current element.
