[xsl] for-each loop not working properly in XSL-FO


Subject: [xsl] for-each loop not working properly in XSL-FO

Please bear with me, as I'm new to XSL....I've stumbled my way through what
you'll read below.  I'm trying to create a new page for each <picture>,
however, the for-each only works with the <area>.  When I use <area> the
resultant pdf works properly, but it is possible to have mulitple <picture>
elements for one <area>.  I feel as though I've tried everything, using
multiple for-each loops, changing the names of the tags, using absolute
referencing, using // referencing.....any suggestions as to why this would
not be working?

Here's an excerpt of my XML...

<pb>
      <section>
            <sectionname>Overview</sectionname>

            <area>
                  <areaname>Defects</areaname>
                  <picture>
                        <caption>Defect-12</caption>
                        <pictureurl>/autoproposal/25.jpeg</pictureurl>

<drawingurl>/autoproposal/LS-4-00_T_Joint.gif</drawingurl>
                        <height>4.50in</height>
                        <width>4.50in</width>
                        <defect>
                              <description>Deck-rusted</description>
                              <cause>Acids in air/ ext and int
moisture</cause>
                              <impact>Safety issues, debris getting into
machinery</impact>
                              <solution>Tear-off and lay another sheet of
deck on top</solution>
                        </defect>
                  </picture>
            </area>

      </section>
</pb>


Here's my XSL-FO...
