Xquery / Xpath what is the meaning of /*:

(: Here $patterns looks like <pattern match="something" replace="else" /> :)

declare function local:transform($text as text(), $patterns as element(pattern)*) {
   if(not($patterns)) then 
      $text
   else
      let $patternsremaining := $patterns[position() > 1],
          $modifiedtext := replace($text, $pattern/@match, $pattern/@replace)
      return 
         if($local:language="French" and not($patterns[@match='le'])) then (
             local:transform($modifiedtext, ($patternsremaining, <pattern match="Londres" replace="London" />))
      )
      else(
         local:transform($modifiedtext, $patternsremaining)
      )
};

/*

is an XPath expression that selects all element children of the root (document) node.

It is equivalent to:

/child::*

As any well-formed XML document must have exactly one top element (child of the document node), the above two expressions select exactly one element -- the top element of the XML document.
