Best way to populate an object from XML
Say I have an employee class. It is just created and needs to populate it's
attribute (i.e. name, id, position), so the class retrieves it's information
from the database in XML format i.e.
<Employee>
<Name>Me</Name>
<ID>10</ID>
<Position>Programmer</Position>
</Employee>
What is the best/most efficient way to extract the attribute information
from the XML? Implement SAX? Make a DOM and parse? Xpath?

If you are using Java check out Castor (www.exolabs.com) and Glue (www.themindelectric.com).

I am currently using VB6. The exolabs.com link didn't work. The Glue is
interesting however it is a java product. I'd be interested in reading Java
articles if you know of any since most Java concepts can be translated back
to VB.

Sorry http://www.exolab.org/.

And is why I said, "if you are using Java"

Check out Javaworld, JavaSkyline, IBM's Java site, Java Developers Journal,
...

Some can but these can't (and a lot of others can't either - if they can
why is the conversion of VB projects to VB.Net so full of "Need to fix"?).
These can't because they use reflection. You will need to go to MS.Net
if you want to use these techniques.
With Java and MS.Net (VB.Net or C#) you can create objects from the database
without writing XML or SQL. With Java, I am using a tool called Hibernate
(an open source tool) without writing any SQL or without an RDBMS to XML
to Object conversion. I would compare it to MS.Net's DataSets but I don't
want to cloud the issue.

if you are using VB6, DOM will be your no brain choice.

XML Serialization might work here. (refer .NET)

Take a look at this article from VB Programmer's Journal.
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnvbpj01/html/pc0107.asp
I had to modify it a bit, but in general it works very well.
