XQuery node is sequence

Is is-node-in-sequence-deep-equal in XQuery? I'm wondering because I've seen the function at xqueryfunctions.com, but I'm not being able to use it.

That function is part of the FunctX XQuery library. There are two methods to use this function:

  1. You download the whole library (select the download which corresponds to your version of XQuery), save it in the same directory as your XQuery program/file and then import the module in your XQuery file, e.g.:

    import module namespace functx = "http://www.functx.com" at "functx-1.0-doc-2007-01.xq";

(: Insert your code here and call the is-node-in-sequence-deep-equal function as seen below :)

functx:is-node-in-sequence-deep-equal($node, $seq)

  2. Instead of downloading the whole library with all functions you can also simply copy paste the specific function which you need as shown on the page you linked to:

    declare namespace functx = "http://www.functx.com"; 
declare function functx:is-node-in-sequence-deep-equal 
  ( $node as node()? ,
    $seq as node()* )  as xs:boolean {

   some $nodeInSeq in $seq satisfies deep-equal($nodeInSeq,$node)
 } ;

(: Insert your code here and call the 'is-node-in-sequence-deep-equal' function as seen below :)

functx:is-node-in-sequence-deep-equal($node, $seq)

In both examples you simply replace $node and $seq with your variables.
