(again) issue with lpath and conditional

(again) issue with lpath and conditional

[Pablo Rodriguez]

Dear list,

I have the following sample:

  \startbuffer[demo]
  <doc>
    <pre class="tex typeset fullwidth">
      <code>
        a
      </code>
    </pre>
    <pre class="tex typeset">
      <code>
        b
      </code>
    </pre>
  </doc>
  \stopbuffer

  \startxmlsetups xml:initialize
     \xmlsetsetup{#1}{doc}{xml:*}
     \xmlsetsetup{\xmldocument}
        {pre[contains(@class,'typeset')]/code}
        {xml:pre:code}
  \stopxmlsetups

  \xmlregistersetup{xml:initialize}

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

  \startxmlsetups xml:pre:code
    \xmlinfo{#1}
    \xmlpath{#1}
    \xmldoifelse{#1}{../pre[contains(@class,'fullwidth')]}
    %~ \xmldoifelse{#1}{{pre[class*="fullwidth"]}}
      {\startpar Full–width.\stoppar}
      {\startpar Another width.\stoppar}
  \stopxmlsetups

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

It is beyond my kmowledge why the lpath
"{../pre[contains(@class,'fullwidth')]}" doesn’t return true, when
\xmlinfo shows "[code]" and \xmlpath is "doc/pre/code" (indices aren’t
relevant here).

Neither does the css selector work.

What am I missing in the lpath and the css selector?

Many thanks for your help,

Pablo
