Load XML Document Content In Table

I have a table having XML column. I want to read a XML document and insert content of the XML file into this xml column.
CREATE TABLE [XMLTest](
[DataAsXML] [xml] NULL,

[CreatedDate] [datetime] NULL
)

I have tried the following query
declare @filepath varchar(100)

declare @filename varchar(100)

set @filename = 'Referred'

set @filepath = 'D:ReportOutput'+ @FileName +'.xml'

print @filepath

insert into XMLTest

SELECT xCol,getdate()

FROM (SELECT * FROM OPENROWSET

(BULK @filepath,SINGLE_BLOB) AS xCol) AS R(xCol)



Problem is that When I give complete file path for BULK instead of variable name i.e. BULK 'C:Test.xml', query runs fine. But when I try to use @filepath, I get error "Incorrect syntax near '@filepath'." What am I doing incorrect? Also,If some one can suggest a better approach to load content of XML document to table?
