<h1>XQuery Adding Elements and Attributes</h1>
<a href="xquery_syntax.asp"><img alt="previous" border="0" src="../images/btn_previous.gif" /></a>
<a href="xquery_select.asp"><img alt="next" border="0" src="../images/btn_next.gif" width="100" height="20" /></a>
<hr />
<h2>The XML Example Document</h2>
<p>We will use the "books.xml" document in the examples below (same
XML file as in the previous chapters).</p>
<p><a target="_blank" href="books.xml">View the "books.xml" file in your browser</a>.</p>
<hr />
<h2>Adding Elements and Attributes to the Result</h2>
<p>As we have seen in a previous chapter, we may include elements and attributes
from the input document ("books.xml) in the result:</p>
<table width="100%" border="1" class="ex" cellspacing="0" id="table4">
<tr>
<td>
<pre>for $x in doc("books.xml")/bookstore/book/title
order by $x
return $x</pre>
</td>
</tr>
</table>
<p>The XQuery expression above will include both the title element and the lang
attribute in the result, like this:</p>
<table width="100%" border="1" class="ex" cellspacing="0" id="table5">
<tr>
<td>
<pre><title lang="en">Everyday Italian</title>
<title lang="en">Harry Potter</title>
<title lang="en">Learning XML</title>
<title lang="en">XQuery Kick Start</title></pre>
</td>
</tr>
</table>
<p>The XQuery expression above returns the title elements the exact same way as
they are described in the input document.</p>
<p>We now want to add our own elements and attributes to the result!</p>
<h3>Add HTML Elements and Text</h3>
<p>Now, we want to add some HTML elements to the result. We will put the result
in an HTML list - together with some text:</p>
<table width="100%" border="1" class="ex" cellspacing="0" id="table6">
<tr>
<td>
<pre><html>
<body></pre>
<pre><h1>Bookstore</h1></pre>
<pre><ul>
{
for $x in doc("books.xml")/bookstore/book
order by $x/title
return <li>{data($x/title)}. Category: {data($x/@category)}</li>
}
</ul></pre>
<pre></body>
</html></pre>
</td>
</tr>
</table>
<p>The XQuery expression above will generate the following result:</p>
<table width="100%" border="1" class="ex" cellspacing="0" id="table7">
<tr>
<td>
<pre><html>
<body></pre>
<pre><h1>Bookstore</h1></pre>
<pre><ul>
<li>Everyday Italian. Category: COOKING</li>
<li>Harry Potter. Category: CHILDREN</li>
<li>Learning XML. Category: WEB</li>
<li>XQuery Kick Start. Category: WEB</li>
</ul></pre>
<pre></body>
</html></pre>
</td>
</tr>
</table>
<h3>Add Attributes to HTML Elements</h3>
<p>Next, we want to use the category attribute as a class attribute in the HTML
list:</p>
<table width="100%" border="1" class="ex" cellspacing="0" id="table10">
<tr>
<td>
<pre><html>
<body></pre>
<pre><h1>Bookstore</h1></pre>
<pre><ul>
{
for $x in doc("books.xml")/bookstore/book
order by $x/title
