Just after I posted the question, I stumbled across this answer. Don't know why I couldn't find it in prior searches. It was the answer I was looking for. Here is the query that works:
Query
select Name
,xml_data.value('(/data/info/@x)[1]', 'int') as [Info.x]
,xml_data.value('(/data/info/@y)[1]', 'int') as [Info.y]
,xml_data.value('(/data/info/.)[1]', 'varchar(10)') as [Info]
from #temp
Result
Name Info.x Info.y Info
------- -------- -------- ---------
one 42 99 Red
two 27 72 Blue
three 16 51 Green
four 12 37 Yellow
.
------ Edit [2014-01-29] ------
I found another case that is worth adding to this answer. Given multiple <info>
elements within the <data>
element, it is possible to return all <info>
nodes by using cross apply
:
create table #temp (id int, name varchar(32), xml_data xml)
insert into #temp values
(1, 'one', '<data><info x="42" y="99">Red</info><info x="43" y="100">Pink</info></data>'),
(2, 'two', '<data><info x="27" y="72">Blue</info><info x="28" y="73">Light Blue</info></data>'),
(3, 'three', '<data><info x="16" y="51">Green</info><info x="17" y="52">Orange</info></data>'),
(4, 'four', '<data><info x="12" y="37">Yellow</info><info x="13" y="38">Purple</info></data>')
select Name
,C.value('@x', 'int') as [Info.x]
,C.value('@y', 'int') as [Info.y]
,C.value('.', 'varchar(10)') as [Info]
from #temp cross apply
#temp.xml_data.nodes('data/info') as X(C)
drop table #temp
This example returns the following dataset:
Name Info.x Info.y Info
--------- ----------- ----------- ----------
one 42 99 Red
one 43 100 Pink
two 27 72 Blue
two 28 73 Light Blue
three 16 51 Green
three 17 52 Orange
four 12 37 Yellow
four 13 38 Purple
