[xquery-talk] Returning dublicates

[EXTERNAL Kruse Peter (Praktikant; CR/AEF4)]

Hi list, 
You are always a very big help for me, so i feel free to ask more questions.

I have an XML tree (of course) and want to find those nodes with certain properties, which exists twice (or more).

So i have
<A>
	<B>mary</B>
	<B>tom</B>
	<B>bob</B>
	<B>mary</B>
	<B>bob</B>
</A>

And i'd like to have a result like
<A>
	<B>mary</B>
	<B>bob</B>
</A>

Note: <B>tom</B> is not included in the result, because there is only one occurance of <B>tom</B>

Thank you all for your patients and have a nice weekend

Mit freundlichen Grüßen, Best Regards
	Peter
