XML Query Issues

I pull the following XML from a field in SQL Server 2008 and need to query into the string to get the values. Each attempt has returned NULL or nothing at all.

CODE

<ScheduleDefinition xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <StartDateTime xmlns="http://schemas.microsoft.com/sqlserver/2006/03/15/reporting/reportingservices">2010-11-19T15:35:00.000-06:00</StartDateTime>
    <WeeklyRecurrence xmlns="http://schemas.microsoft.com/sqlserver/2006/03/15/reporting/reportingservices">
        <WeeksInterval>1</WeeksInterval>
        <DaysOfWeek>
            <Monday>true</Monday>
            <Tuesday>true</Tuesday>
            <Wednesday>true</Wednesday>
            <Thursday>true</Thursday>
            <Friday>true</Friday>
        </DaysOfWeek>
    </WeeklyRecurrence>
</ScheduleDefinition>

The following code is used to return values. I have been able to use the code for other XML strings but this one fails. Just FYI - This is data from the SSRS Subscriptions table in the MatchData field. MSDN articles place the StartDateTime inside WeeklyRecurrence but that is not actually true.

CODE

DECLARE        @TO XML
DECLARE        @String VARCHAR(MAX)


SELECT        @TO = MatchData
FROM        [ReportServer].dbo.Subscriptions
WHERE        SubscriptionID = '9B1AF007-00AB-45E0-9C26-386E49BE926B'

SELECT        @String = @TO.value (N'(/ScheduleDefinition/StartDateTime)[1]',N'VARCHAR(MAX)')


SELECT        @String AS TEST

Thanks in advance for any help.

OK, I found the answer. It is ugly but works when you strip out the XML tags. Here is what worked.

CODE

DECLARE        @TO XML
DECLARE        @String NVARCHAR(MAX)


SELECT        @TO = REPLACE(REPLACE(CAST(MatchData AS NVARCHAR(MAX)),' xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"',''),' xmlns="http://schemas.microsoft.com/sqlserver/2006/03/15/reporting/reportingservices"','')
FROM        [ReportServer].dbo.Subscriptions
WHERE        SubscriptionID = '9B1AF007-00AB-45E0-9C26-386E49BE926B'


SELECT        @String = @TO.value (N'(/ScheduleDefinition//Monday)[1]',N'VARCHAR(MAX)')


SELECT        @String AS TEST
