Straight from BOL SQLSERVER2K8 ... "OPENXML" (/w substitution):

DECLARE @idoc int
DECLARE @doc varchar(1000)

SET @doc ='<test>
		 <dbo.job>
			<job_no>234234</job_no>
			<crew_no>64850</crew_no>
			<begindate></begindate>
			<enddate></enddate>
		  </dbo.job>
		  <dbo.job>
			<job_no>234</job_no>
			<crew_no>234</crew_no>
			<begindate></begindate>
			<enddate></enddate>
		  </dbo.job>
		  <dbo.job>
			<job_no>324</job_no>
			<crew_no>234234</crew_no>
			<begindate></begindate>
			<enddate></enddate>
		  </dbo.job>
	</test>	'

That's the look to the data.

EXEC sp_xml_preparedocument @idoc OUTPUT, @doc
SELECT    *
FROM       OPENXML (@idoc, '/test/DBO.JOB',2)
            WITH (JOB_NO  int,
                  CREW_NO int,
                  BEGINDATE datetime,
                  ENDDATE datetime)

The "OPENXML" help states "Execute a SELECT statement that uses the OPENXML rowset provider". There is another way to do all this. But it's not via OPENXML. See "XPath". Same ... JUST as complicated.

The output:

JOB_NO	CREW_NO	BEGINDATE	         ENDDATE
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
234234	64850	1900-01-01 00:00:00.000	 1900-01-01 00:00:00.000
234	234	1900-01-01 00:00:00.000	 1900-01-01 00:00:00.000
324	234234	1900-01-01 00:00:00.000	 1900-01-01 00:00:00.000
