How to migrate C++ code to MSXML 4

[malhenry]

Hi,

How does one migrate C++ code from MSXML 1.0 to version 4.0 ? I have
installed version 4.0, but I suspect my code is using version 1.0 or some
version prior to 4.0.
My stdafx.h file does contain the following lines:

// Microsoft DOM Control Support
#import "msxml.dll" named_guids raw_interfaces_only

Thanks.

The online MSXML SDK has some sections that should help, see

first for the different program ids and files that belong to the
different versions.
Then check

My code is still not executing my query properly.
BSTR bstrQuery = ::SysAllocString( L"//Tra/incident[active='1'and city='TO'
and contains(event,'ollision')]" );

Here are the changes, that I made to my code:
1. change all occasions of MSXML:: to MSXML2::

2. change all occasions of IXMLDomDocument to IXMLDomDocument2

3. change:
#import "msxml.dll" named_guids raw_interfaces_only
to:
#import "msxml4.dll" named_guids raw_interfaces_only

However the following code returns XSLPattern:
pDoc->getProperty(bs, &Var);

I thought that version 4.0 default was XPath?
What else do I need to change in my code to make it use MSXML ver 4.0 ??

Thanks.
