Expat
<br> Expat bindings for .NET/C#.
About
Expat, a C99 library for parsing XML 1.0 Fourth Edition, started by James Clark in 1997. Expat is a stream-oriented XML parser. This means that you register handlers with the parser before starting the parse. These handlers are called when the parser discovers the associated structures in the document being parsed from.
Bindings
These bindings are intended to provide most of the features available between libexpat and .NET
All P/Invoking functions added can be found in PInvoke
class that is publicy visible.
Basic Parser
This bindings already has a simple parser implemented by default, which basically will redirect all of the P/Invoking callbacks and convert in a simple and practical way and will fire the events as needed.
