XSD Pattern Validation

[Chin Jin Phua]

Hi,

Anyone know how to specify a <XS:Pattern> so as to include a set of
allowable characters? For example, I would like to allow all characters
except QUOTE, PERCENT and AMPERSAND? Is that even possible to specify it in
the XSD Schema?

Thanks
CJ

The regular expression pattern language is defined here:
<http://www.w3.org/TR/xmlschema-2/#regexs>
it allows 'negative character groups' with [^list-of characters-here] e.g.
[^'%&]
of course inside of an XML document you need to escape the ampersand e.g.
[^'%&amp;]
