{
		let $x := fn:doc("xmldatabasefile.xml")/bookstore/book/title[fn:contains(.,'Learning
XML')]/parent::*
		return $x
	}
	
returns:

...<p>
         <book category="WEB">
            		
            <title lang="en">
               			Learning XML
               		
            </title>

            <price>39.95</price>
            	
         </book>
      </p>...

Why is the full stop applied before the comma, because this is not
specified as an option in the specification about 'fn:contains'?

Not quite, returns:

...<p>
         		
         		
         		
         		
         	
      </p>...


if 'return' is changed to 'return $x/element()', the result is as
'return $x', but interestingly a removal of new line white space.
