xpath question

From: "ms" <bg@--.--->

hi all,

I have a doc that looks like this:

<A>
    <B></B>
    <B></B>
    <B></B>
    <B></B>
    <B></B>
    <C></C>
    <C></C>
    <C></C>
    <Z></Z>
</A>

I would like to be able to pull out the unique (DISTINCT as  I know it) 
values under A. i.e. the results I would like are:

    <B></B>
    <C></C>
    <Z></Z>

I can't work out get the xpath to get these results, it must be something 
like "A/*[not(name() = preceding-sibling::A/*name())]" but my little brain 
can't work it out.

Anyone?

TIA
