Getting specific nodes displayed in a table using xsl

hi,
i'm having a huge problem getting my xml in a table with xsl !


this is my xml,

<?xml version="1.0" encoding="ISO-8859-15"?>
<objects>
<object avenue="auctions" id="2809755">
<room id="1401"/>
<title>Kachel op aardgas Wellstraler 7,60 kW</title>
<language>nl</language>
<image id="1755466"/>
</object>
<object avenue="auctions" id="2913991">
<room id="1401"/>
<title>SPLINTERNIEUWE MAZOUTTANK</title>
<language>nl</language>
<image id="1820070"/>
</object>
<object avenue="auctions" id="3004679">
<room id="1401"/>
<title>magnifique feux au bois</title>
<language>fr</language>
<image id="1760827"/>
<image id="1760828"/>
</object>
<object avenue="auctions" id="3004679">
<room id="1401"/>
<title>magnifique feux au bois</title>
<language>fr</language>
<image id="1760827"/>
<image id="1760828"/>
</object>
<object avenue="auctions" id="2913991">
<room id="1401"/>
<title>SPLINTERNIEUWE MAZOUTTANK</title>
<language>nl</language>
<image id="1820070"/>
</object>
</objects>


Now I have to get only the images from the nodes with language=nl into a table with 3 cells / row.
Is there a way to count how many nodes i have with language=nl and then loop through them ? Or maybe another way to do this.

Every suggestion is welcome !

thanks,
wendy
