[MarkLogic Dev General] Is there any code available that simply descends through a document node and discovers and prints out the namespace associated with each element?

I hope the example below helps.  It exposes the complete path of 
elements from the document element to each element in the instance.

~/t $ cat paths.xml
<hello xmlns:abc="urn:X-abc">
   <abc:def>
     <ghi xmlns="urn:X-ghi"/>
   </abc:def>
</hello>
~/t $ cat paths.xq
'&#xa;',
for $each in doc( 'paths.xml' )//*
   return concat( '/',
                  string-join( $each/ancestor-or-self::*/concat('{',
 
namespace-uri-for-prefix(substring-before(name(.),':'),.),
                                           '}',local-name(.)),'/'),
                  '&#xa;' )

~/t $ xquery paths.xq
<?xml version="1.0" encoding="UTF-8"?>
  /{}hello
  /{}hello/{urn:X-abc}def
  /{}hello/{urn:X-abc}def/{urn:X-ghi}ghi
