V9.1 Insert Trigger to extract attribute from the XML document being

I have a  test table
//---------------------------
name    varchar(32)
version  varchar(16)
profile   XML
//---------------------------
The content of the XML file is
<sampleprofile  name="joe"  version="123">
        <phone>123456789</phone>
...
...
</sampleprofile>
//------------------------------------

While inserting a new row , I want to populate the 'name' and
'version' columns from the content of the XML data.
Is it possible to write a Trigger to manupulate the XML data before
its inserted? To make thing more interesting the table has a unique
index on name+version.
