I have several template matches at several stages in a hierarchy of elements, i am trying to find an xpath staement to find out if any of a particuler elements lowest children have an attirbute called "minimum".
e.g. given this hierarchy
<1>
<2>
<3><4 minimum="true"></4><4></4><4 minimum="true"></4><4></4></3>
<3><4></4><4></4></3>
</2>
<2>
<3><4></4><4></4><4></4></3>
</2>
</1>

e.g. when it template matches for "2" i am trying to say if any "4" elements below the current element have a minimum attribute then execute some code.....
i would like to do the smae for other elemnts such as "3"-- if there are any "4" elements below the current element have a minimum attribute then execute some code

does anyone know how to find out whether any of the lowest children in a hierarchy have a particuler attribute??

To look anywhere below oneself, use ".//" ... to look for any element use "*" ... to filter only those elements that do not have any element, comment or PI children (i.e. lowest in the hierarchy), use the predicate "[not(node())]" and to check for a particular attribute existing use the predicate "[@minimum]".

So, the test returning a boolean true would probably be:

test="..//*[not(node())][@minimum]"

I hope this helps.
