Is it possible to do 'not' matching in XPath?

Question

Is it possible to create an XPath expression that matches all child nodes that are not of a certain name? E.g.

<a>
 <b />
 <c />
 <d />
 <e />
 <f />
 <g />
</a>

How would I select all children of the 'a' node that are not a 'b' node?

Answer 1

/a/*[not(self::b)]

Answer 2

Or with XPath 2.0

/a/(* except b)
