Hi, opening a new sheet in the GUI I just executed:
inspect:functions("http://www.w3.org/2005/xpath-functions")
and this is what I got: Error: Stopped at http://www.w3.org/2005/xpath-functions, 1/6: [XPST0003] Processing instruction has illegal name: xml. Optimized Query: inspect:functions("http://www.w3.org/2005/xpath-functions") The Query itself is, as returned by BaseX, interestingly, an XHTML file, which seems to have been produced via Saxon, here are the first lines:
<?xml version="1.0" encoding="UTF-8"?>
<!--XSLT Processor: Saxonica SAXON HE 9.6.0.7-->
<html xmlns="http://www.w3.org/1999/xhtml" lang="EN">

    <nav id="toc">
      <h2><a id="contents"/>Table of Contents </h2>
      <ol class="toc">
        <li>
          <a href="#intro">
            <span class="secno">1 </span>

          </a>
          <ol class="toc"/>
        </li>
And here is the QueryPlan: Query Plan:
<QueryPlan compiled="true" updating="false">
  <InspectFunctions name="inspect:functions" type="(function(*))*">
    <Str type="xs:string" size="1">http://www.w3.org/2005/xpath-functions
</Str>
  </InspectFunctions>
</QueryPlan>

Hi Andreas, I think you are calling the inspect function function on the following HTML Page: https://www.w3.org/2005/xpath-functions/ <https://www.w3.org/2005/xpath-functions/> Per documentation, the function does the following:

As the URI contains no XQuery module, the function will error. Currently inspect:functions only works on user-defined modules. Hope this helps! Michael

Sorry for late reply, I am surrounded by work. Thanks for clarifying.
