SQL Server - returning xml child nodes for xml column

Question

Given table T with columns:

ID UNIQUEIDENTIFIER
CreatedDate DATETIME
XmlData XML

Where XmlData is structured like:

<application>
    <details firstname="first" lastname="last">
        <statement>statement</statement>
    </details>
    <educationHistory>
        <education subject="subject1" />
        <education subject="subject2" />
    </educationHistory>
    <experienceHistory>
        <examiningExperienceHistory>
            <examiningExperience module="module1" />
            <examiningExperience module="module2" />
        </examiningExperienceHistory>
        <teachingExperienceHistory>
            <teachingExperience module="module1" />
            <teachingExperience module="module2" />
        </teachingExperienceHistory>
    </experienceHistory>
</application>

I need to return an extract like so:

ID Date       FirstName LastName Education    ExaminingExp TeachingExp
-----------------------------------------------------------------------
1  02-10-2012 First     Last     <xmlextract> <xmlextract> <xmlextract>

So far I have:

SELECT ID,
       CreatedDate [Date],
       XmlData.value('(application/details/@firstname)[1]','varchar(max)') [FirstName],
       XmlData.value('(application/details/@lastname)[1]','varchar(max)') [LastName]
FROM T

I'm struggling with thee last three columns. For each record, I need to list teaching/examining experience, and education. Can anybody help?

Answer 1

Use .query to extract xml.

eg

select 
XmlData.query('/application/educationHistory/*'),
XmlData.query('/application/experienceHistory/examiningExperienceHistory/*'),
XmlData.query('/application/experienceHistory/teachingExperienceHistory/*')
