xml - Search based on count of particular word -


below sample xml file.

<docs>  <doc>   <name>doc 1</name>   <info>hurray</info>  </doc>  <doc>   <name>doc 2</name>   <info>brinjal king of vegetables.</info>  </doc>  <doc>   <name>doc 3</name>   <info>alexandar great king. desire conquer world , rule  world king.</info>  </doc>  <doc>   <name>doc 4</name>   <info>i love cherries.</info>  </doc>  <doc>   <name>doc 5</name>   <info>mango king of fruits. alphonso king of mangoes. alphonso king's king.</info>  </doc> </docs>

i want search tag word "king" , return output. know simple... :)

but order of should in order of word searched (here king) ie numbers come first.

doc 5 (3 times king) doc 3 (2 times king) doc 2 (1 time king)

as asked question before on basex mailing list assume using basex processor. assuming $doc holds provided xml input, following shows desired result:

for $e in $doc//doc let $copy := copy $c := $e/info modify () return $c let $count := ft:count($copy[. contains text 'king']) order $count descending $count > 0 return <result>{$e/name}<count>{$count}</count></result>

there 2 things special here:

  • the $copy statement simple copy , necessary, because ft:count expecting database node input. if fragment in database don't need this.
  • ft:count vendor-specific basex, unfortunately not part of full text specification.
