SQL Server 2008 :: Parsing Out XML On Same Level

I am trying to parse out

<Discharge_x0020_Time>
<time>
<Hour>11</Hour>
<Minute>:00</Minute>
<AM_x002F_PM>AM</AM_x002F_PM>
</time>
</Discharge_x0020_Time>

Into Hours, minutes, and ampm

I use

Select...
,DISCHARGEHOUR.value('(./Discharge_x0020_Time/time/Hour)[1]', 'varchar(10)') AS [hour]
,DISCHARGEMINUTES.value('(./Discharge_x0020_Time/time/Hour:minute)[1]', 'varchar(10)') AS [Minutes]
,DISCHARGEAMPM.value('(./Discharge_x0020_Time/time/Hour/minute/AM_x002F_PM)[1]', 'varchar(10)') AS [ampm]

FROM ...
CROSS APPLY data.nodes('/Data') a(DISCHARGEHOUR)
CROSS APPLY data.nodes('/Data') b(DISCHARGEMINUTES)
CROSS APPLY data.nodes('/Data') b(DISCHARGEAMPM)

But minutes AND AMPM come up as NULL I assume I am setting up something wrong with the level on minutes AND AMPM. Also, can I disregard the ":" in the minutes.
