MSXML/W3C pattern value problem

Posted on 2001-07-03

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.

I know it's bad, but it's true.

Try to use any Java parser, e.g. Xerces. If you like Windows and COM technology you may use VJ++ for COM DLL creating ...
... and you can partially implement DOMDocument interface.
