    copied!<p>First, your exact query shouldn't be producing that output. You must be using this instead (because of the <strong>default namespace declaration on your input</strong>):</p> <pre><code>declare namespace xsd = "http://www.w3.org/2001/XMLSchema"; declare namespace xsi = "http://www.w3.org/2001/XMLSchema-instance"; declare namespace x = "www.example.com"; declare default element namespace "http://www.example.com"; for $s in /x:Students/x:Student let $firstName := $s/x:Name/x:First-Name let $lastName := $s/x:Name/x:Last-Name let $email := $s/x:Email order by $lastName ascending return &lt;row&gt; &lt;first-name&gt; { $firstName } &lt;/first-name&gt; &lt;last-name&gt; { $lastName } &lt;/last-name&gt; &lt;email&gt; { $email } &lt;/email&gt; &lt;/row&gt; </code></pre> <p>That indeed output:</p> <pre><code>&lt;row xmlns="http://www.example.com"&gt; &lt;first-name&gt; &lt;First-Name xmlns="www.example.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" &gt;Alexander&lt;/First-Name&gt; &lt;/first-name&gt; &lt;last-name&gt; &lt;Last-Name xmlns="www.example.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" &gt;Mart&lt;/Last-Name&gt; &lt;/last-name&gt; &lt;email&gt; &lt;Email xmlns="www.example.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" &gt;Alexander@yahoo.com&lt;/Email&gt; &lt;/email&gt; &lt;/row&gt; </code></pre> <p><strong>WHY?</strong>: Because your sequence constructor <code>{ $firstName }</code> output the node instace referenciated by <code>$firstName</code> not its string-value. That should be:</p> <pre><code>declare namespace x = "www.example.com"; declare default element namespace "http://www.example.com"; for $s in /x:Students/x:Student let $firstName := $s/x:Name/x:First-Name let $lastName := $s/x:Name/x:Last-Name let $email := $s/x:Email order by $lastName ascending return &lt;row&gt; &lt;first-name&gt; { $firstName/string() } &lt;/first-name&gt; &lt;last-name&gt; { string($lastName) } &lt;/last-name&gt; &lt;email&gt; { normalize-space($email) } &lt;/email&gt; &lt;/row&gt; </code></pre> <p>Output:</p> <pre><code>&lt;row xmlns="http://www.example.com"&gt; &lt;first-name&gt;Alexander&lt;/first-name&gt; &lt;last-name&gt;Mart&lt;/last-name&gt; &lt;email&gt;Alexander@yahoo.com&lt;/email&gt; &lt;/row&gt; </code></pre>
