Concise question, concise answer:

Forget the XML syntax, use JXPath instead of JEXL for expressions... Like:

<document>
  #foreach $header in {request/headers}
    #if {starts-with($header/name, 'X-'}
      <paragraph bold="true">
    #else
      <paragraph>
    #end
      The header called &quot;{$header/name}&quot;
      has value &quot;{$header/value}&quot;
    </paragraph>
  #end
</document>

Given the current headers:

X-Test-Header: testvalue
Content-Length: 100

Would produce:

<document>
  <paragraph bold="true">
    The header called &quot;X-Test-Header&quot;
    has value &quot;testvalue&quot;
  </paragraph>
  <paragraph>
    The header called &quot;Content-Length&quot;
    has value &quot;100&quot;
  </paragraph>
</document>
