XSL checkbox

Hi!
I have a problem!
I have an XML like this:

<?xml version="1.0" encoding="utf-8" ?>
<?xml:stylesheet type="text/xsl" href="titles.xsl" ?>
<titlelist>
  <titles title_id="BU1032" title="The Busy Executive&apos;s Database Guide"
type="business    " pub_id="1389"
  price="19.99" advance="5000" royalty="10" ytd_sales="4095" notes="An
overview of available database systems with
  emphasis on common business applications. Illustrated."
pubdate="1991-06-12T00:00:00"/>

<titles title_id="BU1111" title="Cooking with Computers: Surreptitious
Balance Sheets" type="business    "
  pub_id="1389" price="11.95" advance="5000" royalty="10" ytd_sales="3876"
notes="Helpful hints on how to use your
  electronic resources to the best advantage."
pubdate="1991-06-09T00:00:00"/>

</titlelist>

and I want an XSL
which have for every row with the title from xml an checkbox and when I
check this checkbox the background color of row is changed!
