RE: [xsl] XPath statement for traversing a nested node structure

["Kenny Akridge" <kakridge@xxxxxxxxxxxxx>]

The only way I know to do that in version 1.0 is to take a count() from
your context.  

The code I gave you will do that.  I might be misinterpreting you
though.

Kenny,

I will try your suggestion above. I am having problems with XPath based 
upon my nested xml file structure.

Is there a XPath expression that while I am traversing my nested xml 
input file I can determine how many OBJECT elements exist between each 
<TABLE> </TABLE> structure or <DPROW></DPROW>. With the nesting 
structure of my xml input file I can have tables nested within dprows 
and objects within each of those dprows.
