[xsl] XPath Traversing UP the Hierarchy

["Grant Bryce" <grant_bryce@xxxxxxxxxxx>]

Good Afternoon.  I am new to Xpath, XSLT and FOP so any help would be 
greatly appreciated!!!

I have an xml doc with the following structure:

Contract -> Estimate ->itemGroup -> topSecion ->Section -> Item ->Location

In my XSL-FO I am essentially traversing through all locations that are 
under the root contract.  For-each of these locations I then want to check 
and see if any Item has this location (by comparing a Location element).

My problem is while at the lowest level of Location I need to step up the 
hierarchy to the itemGroup level to check only those items.  I have tried a 
number of variations but cant seem to get it quite right.

Any help would be greatly appreciated!!!

The inner loop has been my problem and have tried these options already with 
no success: 1. <xsl:for-each select=" 
ancestor-or-self::node()/ancestor-or-self::node()/ancestor-or-self::node()/ancestor-or-self::node()/items">
2. <xsl:for-each 
select="ancestor::node()/ancestor::node()/ancestor::node()/ancestor::node()/items">
3. <xsl:for-each 
select="parent::node()/parent::node()/parent::node()/parent::node()/items">

       <fo:table-body>
           <xsl:for-each select="./topSections/sections/items/locations">
               <xsl:variable name="locName"><xsl:value-of select="name" 
/></xsl:variable>
               <fo:table-row>
                   <fo:table-cell>
                       <fo:block text-align="center">
                           <xsl:value-of select="$locName" />
                       </fo:block>
                   </fo:table-cell>

                   <!-- Iterate though all items and see if they have a 
location same as outer loop
                        Display the quantity if it is.  -->
                   <xsl:for-each 
select="ancestor::node()/ancestor::node()/ancestor::node()/ancestor-or-self::node()/items">
                           <fo:table-cell>
                               <fo:block text-align="center">
                                   <xsl:for-each 
select="./locations[name=$locName]">  
                                       <xsl:value-of select="quantity" />
                                   </xsl:for-each>
                               </fo:block>
                           </fo:table-cell>
                   </xsl:for-each>                                        
               </fo:table-row>
           </xsl:for-each>       
       </fo:table-body>
