Many thanks for your reply, Wolfgang.

Now I have the minimal sample:

  \startbuffer[demo]
  <doc>
    <div id="header">
      <h2 class="author">author</h2>
    </div>
    <text>
      text
    </text>
  </doc>
  \stopbuffer

  \starttext
  \startxmlsetups xml:initialize
    \xmlsetsetup{#1}{doc}{xml:*}

    \xmlsetsetup{\xmldocument}
      {(div|section)[@id='header']}
      {xml:meta}

   \xmlsetsetup{\xmldocument}
      {(h2|p)[contains(@class,'author')]}
      {xml:title:author}
  \stopxmlsetups

  \xmlregistersetup{xml:initialize}

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

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

  \startxmlsetups xml:meta
    %\aftergrouped{\setupinteraction%
    \setupmetadata
     [author={\xmlconcat{#1}{/h2[contains(@class,'author')]}{, }}]
    %}
  \stopxmlsetups

  \startxmlsetups xml:title:author
    \xmlflush{#1}
  \stopxmlsetups

  \setupinteraction[state=start]
  \xmlprocessbuffer{main}{demo}{}
  \stoptext

With \setupmetadata it breaks compilation.

I know it is not the most elegant code, but in my real environment
xml:title:author outputs text.

Many thanks for your help,

Pablo
