[xsl] Selecting Median of Root to Deepest node

["J. Zhang" <j.zhang@xxxxxx>]

Hi all,

I have written a stylesheet that selects the deepest node when there is 
a match with a keyword. I want to expand my stylesheet so that it also 
selects the median. I need to count the number of nodes for the deepest 
node. I am using Saxon's function saxon:path() to give me the absolute path.

I use xsl:sort and position() = 1 to select the deepest node. I know you 
can use the function count() to count the number of nodes. I want to 
test if a path contains at least 4 nodes while I am at the deepest 
node.  I am trying count(saxon:path()), but that clearly is not working. 
Anyone know how I can pull off this trick?

Thanks
