Multiple conditions in XSLT

I have to use XSLT to transform my XML document into a Bootstrap table. I have done it before using PHP and it was quite simple and I'm trying to adapt it in XSLT.

With PHP I did something like this :

while($line = $request->fetch(PDO::FETCH_ASSOC)) 
{
   echo '<tr ';
   switch($line["category"])
   {
     case "Movie" : echo "class='info'";break;
     case "Tv show" : echo "class='danger'";break;
     case "Music" : echo "class='success'";break;
   }
   echo ' >';
   ...
   echo "</tr>";
}

I tried to do a similar code in XSLT (not using concatenation because we can't) :

<xsl:for-each select="demands/demand">
    <xsl:choose> 
        <xsl:when test="category  = 'Movie'"> 
            <tr class="info">
        </xsl:when> 
        <xsl:when test="category = 'Tv show'"> 
            <tr class="danger">
        </xsl:when> 
        <xsl:when test="categorie = 'Music'"> 
            <tr class="success">
        </xsl:when> 
    </xsl:choose>
    ...
    </tr>
</xsl:for-each>

That doesn't work ("Opening and ending tag mismatch: tr line") because there is only one closing tr tag. Is there any solution to that ? How can I do it the simpliest way ?

Thank's for your help.
