IE8 implements the W3C Selectors API. With this API javascript can
select elements from the DOM tree in a very comfortable way. With the
mshtml.dll the IElementSelector and IDocumentSelector interfaces make
functions querySelector() and querySelectorAll() accessible from C++ and
VisualBasic (VBA). But I can find no way to use them from C# or VB.NET.
After referencing the mshtml.tbl the Interfaces don't show up. Is there
solution to this problem?

most probably because mshtml is not a COM but a native dll (although I
find this weird). What is what you want to do?

I'm trying to simplify a webscraping application.
So I have to figure out how do it with P/Invoke DLLImport :-(

I can't find out how to do this. Has anybody an idea or knows how to do it?

Finally it works! I had to create a new interop assembly from the IE8
mshtml.tlb with tlbimp.exe (from the WIN 6.0A SDK). Now C# sees the new
Interfaces.
