Hi there,<br><br>for $x in (db:fulltext(&#39;work&#39;, &#39;string theory&#39;)/ancestor::*:Doc  except db:fulltext(&#39;work&#39;, &#39;elastic&#39;)/ancestor::*:Doc) <br>return substring(data($x/Publish/PubDate/@d), 7)<br>
<br><br>I am storing Dates in YYYYMMDD Format as &lt;PubDate d=&quot;20040608&quot;&gt; tag. The above query will return<br>the Date of the Document published for the searched criteria. Using the BaseX 7.5, I was able to run the query <br>
correctly. But with 7.6, I am getting error <br><br><b>&quot;Single item expected, (&quot;20040608&quot;, &quot;20040609&quot;) found&quot;</b><br><br><br>-- <br>Have a nice day<br>JBest<br><br><br>
