CXmlParserPlugin class.+

1.+
−
This is the top level class of xmlparserplugin.dll - an Ecom plugin+
−
for use in the Xml framework.+
−
+
−
For full details of the plug-in configuration see the files pmlparser.mmp+
−
and 101faa0a.rss.+
−
+
−
Ecom constructs the plug-in by virtue of a call to the static member+
−
function EcomNewL, a pointer to which is contained in the associated+
−
TImplementationProxy table for the plug-in.+
−
+
−
2.+
−
This class implements the MParser interface defined in xml/parser.h+
−
+
−
3.+
−
The parsing functionality is subcontracted to the Expat parser toolkit,+
−
captured in the class CExpat, see the file cexpat.h.+
