XML File Sample

Parse XML file to read in SQL

DECLARE @hdoc int
DECLARE @doc nvarchar(max)
SelecT @doc = convert(nvarchar(max),xml_data) from XmlImportTest

--Create an internal representation of the XML document.
EXEC sp_xml_preparedocument @hdoc OUTPUT, @doc

--select @hdoc

SELECT *
FROM OPENXML (@hdoc, '/strings/enum')
with (name varchar(100) '@name')

SELECT *
FROM OPENXML (@hdoc, '/strings/enum/field')
with ( name varchar(100) '../@name',
val varchar(100) '@value',
txt varchar(100) '.')

-- Remove the internal representation.
exec sp_xml_removedocument @hdoc

Import XML data into a table

CREATE TABLE XmlImportTest(
xmlFileName VARCHAR(300) NOT NULL,
xml_data XML NOT NULL
)
GO

DECLARE @xmlFileName VARCHAR(300)
SELECT @xmlFileName = 'C:\Documents and Settings\palexander\Desktop\Mingle Meta Data\black_strings.xml'

--dynamic sql is just so we can use @xmlFileName variable in OPENROWSET

EXEC('INSERT INTO XmlImportTest(xmlFileName, xml_data)

SELECT ''' + @xmlFileName + ''', xmlData
FROM(
SELECT *
FROM OPENROWSET (BULK ''' + @xmlFileName + ''' , SINGLE_BLOB) AS XMLDATA
) AS FileImport (XMLDATA)
')
GO
