xpath statement
If you are looking for a simple count of each object within a node(not a
sum of objects that includes the table subnode), then both of these will
work:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
	<xsl:for-each select="//TABLE">
		<xsl:value-of select="concat(count(DPROW/OBJECT),
'&#160;')"/>
	</xsl:for-each>
</xsl:template>
</xsl:stylesheet>

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
	<xsl:apply-templates select="//TABLE"/>
</xsl:template>

<xsl:template match="TABLE">
	<xsl:apply-templates select="DPROW"/>
</xsl:template>

<xsl:template match="DPROW">
	<xsl:value-of select="concat(count(OBJECT), '&#160;')"/>
</xsl:template>
</xsl:stylesheet>

However, if you need the sum then you will need to use some
recurision(off hand this is what I am thinking).

I think your problem with DPROW/OBJECT is that you are getting a count
based on the first table context.

Subject:  XPath statement for traversing a nested node structure

I need some assistance with traversing a nested xml input file
structure.

I need to determine between the begining of one nested structure and 
another the number of occurances of a particular element.

Example:

<TABLE><DPROW><OBJECT></OBJECT></DPROW></TABLE> would yield an occurance

of one OBJECT element using the XPath statement DPROW/OBJECT.

The above XPath statement falls apart though when I introduce nested 
structures.

<TABLE><DPROW><OBJECT></OBJECT><TABLE><DPROW><OBJECT></OBJECT><OBJECT></
OBJECT></DPROW></TABLE></DPROW></TABLE>
Inner most TABLE element has two OBJECT elements and the outer TABLE 
element would yield one OBJECT element.

What is a valid XPath statement need for traversing the nested xml 
structure above?

Any help would be greatly appreciated.
