how to do XQuery - tsql

I got this XML.

<ArrayOfGuid xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
     <guid>475B07C8-CDEA-4000-BAAE-485336190E10</guid>
     <guid>6E5B87BC-CF80-4AB2-939E-ED951FA604AB</guid>
     <guid>31BFDA60-3BB2-49DC-8C69-10F6E1B540CA</guid>
</ArrayOfGuid>

Need to get the results like

BatchGUID
475B07C8-CDEA-4000-BAAE-485336190E10
6E5B87BC-CF80-4AB2-939E-ED951FA604AB
31BFDA60-3BB2-49DC-8C69-10F6E1B540CA

Somehow I am stuck with

DECLARE @BatchGUID XML

SET @BatchGUID = '<ArrayOfGuid xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
                      <guid>475B07C8-CDEA-4000-BAAE-485336190E10</guid>
                      <guid>6E5B87BC-CF80-4AB2-939E-ED951FA604AB</guid>
                      <guid>31BFDA60-3BB2-49DC-8C69-10F6E1B540CA</guid>
                    </ArrayOfGuid>'

DECLARE @t_xml TABLE
(
    BatchGUID XML
)

INSERT INTO @t_xml
SELECT @BatchGUID

SELECT C.* FROM @t_xml
cross apply (select name.value('guid[1]', 'uniqueidentifier') as [BatchGUID] 
from BatchGUID.nodes('//ArrayOfGuid/guid') as c(name)) as C

This is returning me

BatchGUID
NULL
NULL
NULL

Need to know what I'm doing wrong here.

Thanks,

You are so very close!

Your problem is that you're selecting the value of the guid[1] node from within the guid node. Of course, the guid node doesn't contain any children - you want to select the value from that node itself (which is expressed as .)

SELECT C.* FROM @t_xml
cross apply (select name.value('.', 'uniqueidentifier') as [BatchGUID]
from @BatchGUID.nodes('//ArrayOfGuid/guid') as c(name)) as C
