ancestors in lpath

[Pablo Rodriguez]

Dear list,

I have the following sample:

    \startbuffer[demo]
    <doc>
      <div id="u1" class="level1">
        <h1>Unit 1</h1>
        <p>text</p>
      </div>
      <div id="u1a" class="appendices level1">
        <h1 class="hidden">Unit 1</h1>
        <div id="sum1" class="summary level2">
          <h2>Summary</h2>
          <p>summary</p>
        </div>
        <div id="sin1" class="synopsis level2">
          <h2>Synopsis</h2>
          <p>synopsis</p>
        </div>
      </div>
      <div id="u2" class="level1">
        <h1>Unit 2</h1>
        <p>text</p>
      </div>
      <div id="u2a" class="appendices level1">
        <h1 class="hidden">Unit 2</h1>
        <div id="sum2" class="summary level2">
          <h2>Summary</h2>
          <p>summary</p>
        </div>
        <div id="sin2" class="synopsis level2">
          <h2>Synopsis</h2>
          <p>synopsis</p>
        </div>
      </div>
      <div id="u3" class="level1">
        <h1>Unit 3</h1>
        <p>text</p>
      </div>
      <div id="u3a" class="appendices level1">
        <h1 class="hidden">Unit 3</h1>
        <div id="sum3" class="summary level2">
          <h2>Summary</h2>
          <p>summary</p>
        </div>
        <div id="sin3" class="synopsis level2">
          <h2>Synopsis</h2>
          <p>synopsis</p>
        </div>
      </div>
    </doc>
    \stopbuffer

    \startxmlsetups xml:initialize
        \xmlsetsetup{#1}{doc}{xml:*}
        \xmlsetsetup{#1}{[contains(@class,'synopsis')]}
            {xml:specialtitle}
    \stopxmlsetups

    \xmlregistersetup{xml:initialize}

    \startxmlsetups xml:doc
         \xmlflush{#1}
    \stopxmlsetups

    \startxmlsetups xml:specialtitle
        \startpar
          \xmltext{#1}{/h2}·
          \xmltext{#1}{../../div[contains(@class,'appendices')]/h1}
        \stoppar
    \stopxmlsetups

    \starttext
        \xmlprocessbuffer{main}{demo}{}
    \stoptext

How should I rewrite "{../../div[contains(@class,'appendices')]/h1" to
get only the corresponding unit for each xml:specialtitle?

I need an ancestor, but I don’t know how to invoke it.

Many thanks for your help,

Pablo
