Re: [MarkLogic Dev General] question regarding a code snippet..

[Jason Hunter]

You just need to add a "return" before the "if", to make it into a  
legal FLWOR statement.

Thanks for the reply. It worked like a charm. On the same note I  
have another question in Xquery in below snippet:

xquery version "1.0-ml";
import module namespace thsr="http://marklogic.com/xdmp/thesaurus";
at "/MarkLogic/thesaurus.xqy";

extractSynonyms("drugs")

declare function extractSynonyms($synTerm)
{
   let $thsrEntry := thsr:lookup("/EBISynonyms/Synonyms.xml",  
$synTerm)

   if(!fn:empty($thsrEntry))
   then $synTerm
   else ""
};

Why is the code erroring out at conditional if statement!!? It seems  
like a simple conditional statement to check whether any synonym  
entries exist for the given term.

I appreciate your help.

Thanks,

A couple of things here,

You need to query for you elements in the thesaurus namespace.

declare namespace thesaurus = "http://marklogic.com/xdmp/thesaurus";;

You also are already at the "entry" element when you defined the  
variable $synEntry.  Note, the query is now  fn:count($synEntry/ 
thesaurus:synonym)  (skip the entry and add the namespace).

Try the following:

xquery version "1.0-ml";

declare namespace thesaurus = "http://marklogic.com/xdmp/thesaurus";;

let $synEntry := <entry xmlns="http://marklogic.com/xdmp/thesaurus";>
          <term>zinc</term>
          <part-of-speech>noun</part-of-speech>
          <qualifiers>
            <qualifier>vicinity</qualifier>
          </qualifiers>
          <synonym>
            <term>zinc chelate</term>
          </synonym>
          <synonym>
            <term>zinc content</term>
          </synonym>
          <synonym>
            <term>zinc dust</term>
          </synonym>
          <synonym>
            <term>zinc isotopes</term>
          </synonym>
          <synonym>
            <term>zinc radioisotopes</term>
          </synonym>
          <synonym>
            <term>zinc retention</term>
          </synonym>
          <synonym>
            <term>zincum</term>
          </synonym>
          <synonym>
            <term>zn</term>
          </synonym>
        </entry>

let $synonymsCount := fn:count($synEntry/thesaurus:synonym)

return $synonymsCount

Subject: [MarkLogic Dev General] question regarding a code snippet..

          <synonym>
            <term>zn</term>
          </synonym>
        </entry>

let $synonymsCount := fn:count($synEntry/entry/synonym)

return $synonymsCount


The synonym count is coming out as "0" instead of "8"...still  
couldn't figure out where I am going wrong.

I really appreciate if someone can help me on this.

Thanks,
Srini
