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

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,
Srini

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..

xquery version "1.0-ml";

        <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
