MSXML/W3C pattern value problem
I am using MSXML Parser v4.0 which supports W3C XSD schemas.
When I validate XML against a schema is correctly validates the minLength and maxLength values, however, it appears to completely ignore the pattern value.
I have tried numerous patterns like "\d{32}", "[0-9]{32}" etc. but they do not work.
Any ideas?

David,
Yes, it's true. See "what's new" section in the SDK documentation:
> The MSXML 4.0 Technology Preview does not support regular expressions and identity constraints.

Yury_Delendik,
Not the answer I wanted to hear, but I thought it might be the case.
As this is only a preview version, do you know if the release version of MSXML 4 will contain this functionality?

Also,
Is there another parser which I can use that will perform this validation?
Thanks.
