What is the difference?

[Ashwin]

Hi,

I just wanted to know the difference between Microsoft XML Parser (MSXML)
3.0 Service Pack and the MSXML 4 or 6 Core services? Are they upgrades of
each other or they are different applications and used for different reasons?

Thanks in advance,

Ashwin

MSXML 3 is what IE 6 (and IE 7) use to parse XML document loaded in a
browser window.
MSXML 4 is not an replacement for MSXML 3 which IE continues to use.
MSXML 4 in contrast to MSXML 3 has support for XSD schema validation,
XSD Schema Object Model, improved XSLT performance.
MSXML 6 is the latest, it does not have some older features like XDR
schema support that MSXML 3 and 4 do still have, instead MSXML 6 has
been mainly improved to have MSXML schema validation matching with the
.NET 2.0 schema validation. MSXML 6 also by default has some features
turned of for security reasons (e.g. DTD validation).

See

for more details.
