How do I get the data to return with multiple elements?

How do I get the data to return in multiple title elements rather than one title element?

Returns this

<title>
    Title 1
    Title 2
    Title 3
</title>

Want to return this

<title>Title 1</title>
<title>Title 2</title>
<title>Title 3</title>

Code

(: This gets coordinates from $latLon :)
  let $result := for $coordinates in $latLon/location
                let $lat := $coordinates/lat/text()
                let $lon := $coordinates/lon/text()
(: This uses the coordinates to retrieve a title :)
                let $data := titleDoc:getTitle($lat, $lon)
                let $title := $data//div[@class="title"]/text()
                return
                  <title>{$title}</title>

As @chrisis says, it's hard to tell without looking at your code, but I think you want a for instead of a let here:

  let $title := $data//div[@class="title"]/text()
  return <title>{$title}</title>

The let makes one sequence with all the text nodes, and places them in the <title> element. That's not what you want, you want to iterate over them, creating one title element for each one:

  for $title in $data//div[@class="title"]/text()
  return <title>{$title}</title>

Difficult to answer without seeing the contents of $data. But something like this should work:

for $title in $data//div[@class="title"]
return <title>{data($title)}</title>
