How to replace attribute value of *all* matching elements with XQuery? - sql-server-2005

Question

I'm trying without luck to create a modify() statement to change the value of an attribute in all elements that have that attribute value -- so far I can only get it to change the value in the first matched element. I created an example below of what I have so far, which I'm running in SQL Server 2005:
DECLARE #x XML
SELECT #x = '
<FootballApparel>
<Item Team="Phoenix Cardinals" Type="Hat" Cost="$14.99" />
<Item Team="Indianapolis Colts" Type="Hat" Cost="$14.99" />
<Item Team="Cincinnati Bengals" Type="Hat" Cost="$14.99" />
<Item Team="Phoenix Cardinals" Type="Shirt" Cost="$21.99" />
<Item Team="Indianapolis Colts" Type="Shirt" Cost="$21.99" />
<Item Team="Cincinnati Bengals" Type="Shirt" Cost="$21.99" />
</FootballApparel>
';
SET #x.modify('
replace value of
(/FootballApparel/Item[#Team="Phoenix Cardinals"]/#Team)[1]
with "Arizona Cardinals"
');
SELECT #x;
Running this gives the results below -- only the first instance of Phoenix Cardinals has been changed.
<FootballApparel>
<Item Team="Arizona Cardinals" Type="Hat" Cost="$14.99" />
<Item Team="Indianapolis Colts" Type="Hat" Cost="$14.99" />
<Item Team="Cincinnati Bengals" Type="Hat" Cost="$14.99" />
<Item Team="Phoenix Cardinals" Type="Shirt" Cost="$21.99" />
<Item Team="Indianapolis Colts" Type="Shirt" Cost="$21.99" />
<Item Team="Cincinnati Bengals" Type="Shirt" Cost="$21.99" />
</FootballApparel>
Can you please help me with the correct modify() statement to replace all instances?
Thanks!

Answer 1

You're very close - what you need to do is loop (and there's no other way I know of to do it in this case) and repeatedly replace the values:
WHILE #x.exist('(/FootballApparel/Item[#Team=sql:variable("#oldTeamName")])[1]') = 1
SET #x.modify('
replace value of (
/FootballApparel/Item[#Team=sql:variable("#oldTeamName")]/#Team
)[1]
with sql:variable("#newTeamName")
');
That should do the trick.
