How to execute entire result set of multiple sql statements via sp_executesql?

Question

I have a query that generates multiple insert statements (dynamic sql).  So when I execute this my result set is a table of sql insert statements (one insert statment per row in my source data table).  Like so:
             Select 'INSERT INTO [dbo].[Table_1] ([Col1]) VALUES (' +  SrcData + ')' from SourceDataTbl
How can I completely automate this and execute all these sql statements via sp_executesql?
My plan is to completely automate and execute all this via an SSIS package.
As always any help is greatly appreciated!
fyi-  This is a very simple version of what I am trying to do.  My query probably plugs in 20+ values from the SourceDataTbl into each of the sql insert statements.

Ah, a small error in Visakh's post, which I failed to observe, and then I added one on my own.
DECLARE @SQL Varchar(max)
SELECT @SQL =
   (SELECT 'INSERT INTO [dbo].[Table_1] ([Col1]) VALUES (' +  SrcData +
            ')' + char(10) + char(13)
    from SourceDataTbl
    FOR XML PATH(''), TYPE).value('.', 'nvarchar(max)')
EXEC sp_executesql @SQL
Without ", TYPE" FOR XML returns a string when assigned to a variable. The TYPE thing produces a value of the XML data type, so that we can apply the value method and get string out of the XML.
And why this? Because:
DECLARE @str nvarchar(MAX)
SELECT @str = (SELECT 'Kalle Anka & co' FOR XML PATH(''))
SELECT @str
SELECT @str = (SELECT 'Kalle Anka & co' FOR XML PATH(''), TYPE).value('.', 'nvarchar(MAX)')
SELECT @str
Although the data type is string when , TYPE is not there, it is still XML and characters special to XML are enticised.
Confused? Don't worry, for what you are doing, this is mumbo-jumbo.
