From the sample here:

How would I sum the Ages of Simon and Peter?
CREATE TABLE XmlSourceTable
(
RecordId INT IDENTITY(1,1) NOT NULL PRIMARY KEY,
XmlData XML NOT NULL
)
GO
XmlData = '
<?xml version="1.0" ?>
<Root>
<Person>
<Name>Simon</Name>
<Age>20</Age>
<Skills>
<Skill>Cooking</Skill>
<Skill>Cleaning</Skill>
</Skills>
</Person>
<Person>
<Name>Peter</Name>
<Age>21</Age>
<Skills>
<Skill>Ironing</Skill>
</Skills>
</Person>
</Root>'
INSERT INTO XmlSourceTable(XmlData)
SELECT *
FROM OPENROWSET(
BULK 'C:\XmlSource.xml', SINGLE_BLOB)
AS ImportSource
GO
SELECT
pref.value('(Name/text())[1]', 'varchar(50)') as PersonName,
pref.value('(Age/text())[1]', 'int') as PersonAge,
pref.query('Skills') as PersonSkills
FROM
XmlSourceTable CROSS APPLY
XmlData.nodes('/Root/Person') AS People(pref)
GO

Not sure exactly if this is what you're after but maybe it'll help:
DECLARE @XmlData XML = '
<Root>
<Person>
<Name>Simon</Name>
<Age>20</Age>
<Skills>
<Skill>Cooking</Skill>
<Skill>Cleaning</Skill>
</Skills>
</Person>
<Person>
<Name>Peter</Name>
<Age>21</Age>
<Skills>
<Skill>Ironing</Skill>
</Skills>
</Person>
</Root>'
SELECT [Simon's Age]=x.value('(/Root/Person/Age)[1]', 'INT')
,[Peter's Age]=x.value('(/Root/Person/Age)[2]', 'INT')
FROM (SELECT @XmlData) a(x)
My thought question: Have you ever been told that your query runs too fast?
My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
