Default Traversing UP my hierarchy in XPath

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 can’t 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>



      <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>

Default

If your context node is Location then
..
takes you up one level so
../Location
will give you all the Location elements assuming the only parent of Location is Item.
Is this what you mean?
