Pass XML file as input parameter in stored procedure - sql-server

Question

Is it possible to pass an XML file as a parameter in a stored procedure in SQL Server?
I have tried this but it doesn't do what its supposed to:
DECLARE #XmlString2 as XML <--I have a feeling this is the problem
SET #XmlString2 = 'cast(x as XML)
from openrowset (bulk '''+#FileName+''', single_blob) as T(x)'
DECLARE cur CURSOR LOCAL for
SELECT
PA_ID = XTbl.value('(Answer_ID)[1]', 'varchar(400)'),
Question_ID = XTbl.value('(../../ID)[1]', 'bigint'),
QuestionText = XTbl.value('(../../QuestionText)[1]', 'varchar(200)'),
QuestionType = XTbl.value('(../../QuestionType)[1]','bigint'),
Questionaire_ID = XTbl.value('(../../QuestionaireID)[1]','bigint'),
Filter = XTbl.value('(../../Filter)[1]', 'bigint'),
Value = XTbl.value('(Value)[1]','varchar(400)'),
RequiresExplanation = XTbl.value('(RequiresExplanation)[1]','int'),
ReviewRequired = XTbl.value('(ReviewRequire)[1]','char(1)')
from #XmlString2.nodes('/Questions/Question/PossibleAnswers/PossibleAnswer') as XD(XTbl)
I have the same thing with a hardcoded address of the file and it works, so I was wondering if this is possible so as I can execute the stored procedure with a different file if I need to

Here's an example procedure that accepts XML as a string, and shreds it into tables. It's pretty gnarly to write this by hand, if you're doing many of these best to write some sort of generator based on your table definition.
The inputted xml is pretty simple, and attribute based
<xml>
<agent addr1='123 Main Street' city='Toronto' />
<agent addr1='123 Main Street' city='Toronto' />
</xml>
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[sp_INSERT_agents]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)
drop procedure [dbo].[sp_INSERT_agents]
GO
CREATE PROCEDURE sp_INSERT_agents
#strXML ntext
AS
BEGIN
