Fetch Data From Hierarchy In XML.

My problem is that my:hustyp)[1] only fetches the first occurace of this tag. In my xmlfile this field is a repeating table created in infopath 2007. How do I manage to get the rest dynamically.

------XML-file---------------------------------------
<my:group1>
<my:group2>
<my:hustypTF>5</my:hustypTF>
</my:group2>
<my:group2>
<my:hustypTF>6</my:hustypTF>
</my:group2>
<my:group2>
<my:hustypTF>7</my:hustypTF>
</my:group2>
</my:group1>

WITH xmlnamespaces('http://schemas.microsoft.com/office/infopath/2003/myXSD/2007-01-15T13:29:33' AS my)
SELECT FormData.value('(/my:xxx/my:Formular/my:group1/my:group2/my:hustyp)[1]', 'varchar(99)') AS IdFastBet
FROM MinaDekl
CROSS APPLY FormData.nodes('(/my:xxx/my:Formular/my:group1/my:group2/my:hustyp) as TempTab(testTab1)
