xpath-003

Tests that if cx:xpath returns a string, it’s a text document not a JSON document. This is a test for #755, although that issue is broader than this step.

Test is expected to pass.

The pipeline

<p:declare-step xmlns:cx="http://xmlcalabash.com/ns/extensions"
                xmlns:err="http://www.w3.org/ns/xproc-error" xmlns:p="http://www.w3.org/ns/xproc"
                xmlns:t="http://xproc.org/ns/testsuite/3.0" version="3.2">
   <p:import href="https://xmlcalabash.com/ext/library/xpath.xpl"/>
   <p:output port="result"/>
   <cx:xpath>
      <p:with-input>
         <doc>Test</doc>
      </p:with-input>
      <p:with-input port="xpath">
         <p:inline content-type="text/plain"
                   expand-text="false">"Hello, world."</p:inline>
      </p:with-input>
   </cx:xpath>
   <p:identity>
      <p:with-input>
         <ctype>{p:document-property(., 'content-type')}</ctype>
      </p:with-input>
   </p:identity>
</p:declare-step>

Result

<ctype xmlns:cx="http://xmlcalabash.com/ns/extensions"
       xmlns:err="http://www.w3.org/ns/xproc-error" xmlns:t="http://xproc.org/ns/testsuite/3.0">text/plain</ctype>
