<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>Present the Result In an HTML List</h2>
<p>Look at the following XQuery FLWOR expression:</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 expression above will select all the title elements under the book
elements that are under the bookstore element, and return the title elements in
alphabetical order.</p>
<p>Now we want to list all the book-titles in our bookstore in an HTML list. We
add <ul> and <li> tags to the FLWOR expression: </p>
<table width="100%" border="1" class="ex" cellspacing="0" id="table6">
<tr>
<td>
<pre><span class="insert"><ul>
{</span>
for $x in doc("books.xml")/bookstore/book/title
order by $x
return <span class="insert"><li>{</span>$x<span class="insert">}</li>
}
</ul></span></pre>
</td>
</tr>
</table>
<p>The result of the above will be:</p>
<table width="100%" border="1" class="ex" cellspacing="0" id="table5">
<tr>
<td>
<pre><ul>
<li><title lang="en">Everyday Italian</title></li>
<li><title lang="en">Harry Potter</title></li>
<li><title lang="en">Learning XML</title></li>
<li><title lang="en">XQuery Kick Start</title></li>
</ul></pre>
</td>
</tr>
</table>
<p>Now we want to eliminate the title element, and show only the data inside
the title element:</p>
<table width="100%" border="1" class="ex" cellspacing="0" id="table9">
<tr>
<td>
<pre><ul>
{
for $x in doc("books.xml")/bookstore/book/title
order by $x
return <li>{<span class="insert">data(</span>$x<span class="insert">)</span>}</li>
}
</ul></pre>
</td>
</tr>
</table>
