Query on child node returning parent node

Hi All,

Is there anyway for me to create a query (XPath preferably) that will check
some criteria against a node, and if it matches return the parent node?
What I want to do is check in my jcr:content nodes for all files created
before a certain date and then return the nt:file node, something like this:

/jcr:root//jcr:content[@jcr:lastModified < date]/..

(in regular XPath '..' returns the parent)

Thank you,

Thanks Alessandro, that should work!

Unfortunately the parent axis is not supported, as far as I know at  
least.

  You could use this query instead (replace with your date of course):

/jcr:root//element(*,nt:file)[jcr:content/@jcr:lastModified <  
xs:dateTime('2008-10-13T08:30:25.841-04:00')]

which uses a predicate on a child node (which seems to be supported)  
to obtain the same result.
