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
