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 "{$header/name}"
has value "{$header/value}"
</paragraph>
#end
</document>
Given the current headers:
X-Test-Header: testvalue
Content-Length: 100
Would produce:
<document>
<paragraph bold="true">
The header called "X-Test-Header"
has value "testvalue"
</paragraph>
<paragraph>
The header called "Content-Length"
has value "100"
</paragraph>
</document>
