Getting XML Version

[Norman Chong]

Hi,

I want to get my MSXML version from a vb.net program. I do it with the
following piece of code, but I'm not very happy with that:

Dim Version as String = "4.0"
oXML = CreateObject("Msxml2.DOMDocument.4.0") 'Need version 4.
If oXML Is Nothing Then 'Check the existing version
oXML = CreateObject("MSXML2.DOMDocument.3.0")
Version = "3.0"
If oXML Is Nothing Then
oXML = CreateObject("MSXML2.DOMDocument.2.6")
Version = "2.6"
If oXML Is Nothing Then
oXML = CreateObject("MSXML2.DOMDocument")
Version = "2.0"
If oXML Is Nothing Then
Version = "Not detected"
End If
End If
End If
End If

Does anybody know a more elegant way to do this?

Thanks,
Norman

The .NET framework has its own classes/implementations for XML parsing,
XSLT, XPath, DOM, schema validation, you should not use MSXML from .NET.

It is not clear what you want to achieve, the latest version of MSXML is
MSXML 6 for instance. And MSXML 3, 4, 5, 6 can all coexist on the same
system. The programming id MSXML2.DOMDocument can be bound to MSXML 3
depending on the installation, with the normal IE 6 installation it is
bound to MSXML 3.

Sorry if it was unclear what I want to do - I try it again ;-)
The program should check, if there is MSXML 4.0 installed (it has to do
this for another application, which needs 4.0 - That's why I started
with 4.0 in my code), if not it should get the next lower version which
is installed and show it within a MessageBox.
