HTML table output - html

Question

I've got a XML file that contains this data:
<?xml version="1.0" encoding="iso-8859-1" ?>
<university>
<lecture>
<class>English</class>
<hours>3</hours>
<pupils>30</pupils>
</lecture>
<lecture>
<class>Math</class>
<hours>4</hours>
<pupils>27</pupils
</lecture>
<lecture>
<class>Science</class>
<hours>2</hours>
<pupils>25</pupils>
</lecture>
</university>
Is it possible if I can get an XQuery code that produces this output (below) for me?
<table>
<tr>
<td>English class runs for 3 with 30 pupils</td>
<td>Math class runs for 4 with 26 pupils</td>
<td>Science class runs for 2 with 25 pupils</td>
</tr>
</table>
EDIT: Below is my attempt:
let $classroom := doc("uni.xml")/university/lecture/class
let $hr := doc("uni.xml")/university/lecture/hours
let $pupl := doc("uni.xml")/university/lecture/pupils
<tr>
<table>
for $a in $classroom,
$b in $hr,
$c in $pupl
return <td>{$a} class runs for {$b} with {$c} pupils</td>
</tr>
</table>
I get an error saying I need to return a value, which I already did. If I take out the tr and table tags, it works, but gives me an endless loop result.

Responding to the updated XML, and a bit of your attempted XQuery style which using variables, I'd suggest something like this :
<table>
<tr>
{
for $lecture in doc("uni.xml")/university/lecture
let $class := $lecture/class/string()
let $hours := $lecture/hours/string()
let $pupils := $lecture/pupils/string()
return
<td>{$class} class runs for {$hours} with {$pupils} pupils</td>
}
</tr>
</table>

Basically, the query loop through common parent elements that contains all the needed information; the lecture elements. Then use simple relative XPath/XQuery to extract data from each lecture to produce the required output.
