dc:creator from XML into SQL table - sql

Question

I am trying to store an XML file (Code below) but the the dc:creator is causing an error. I have found from other related questions on here stating that I should use ;WITH XMLNAMESPACES(''http://purl.org/dc/elements/1.1/'' AS dc) but this has not worked either any ideas on what might be the problem/solution ? .
XML file:
<?xml version="1.0" encoding="UTF-8"?>
-<rss xmlns:atom="http://www.w3.org/2005/Atom" xmlns:dc="http://purl.org/dc/elements/1.1/" xml:base="http://talksport.com/rss/sports-news/football/feed" version="2.0">

This is the stored procedure:
CREATE PROCEDURE feed.usp_importXML(#file VARCHAR(8000))
AS
BEGIN
DECLARE #Query VARCHAR(8000)
SET #Query ='
DECLARE #xmlFile as XML
SET #xmlFile = ( cast
SELECT CONVERT(XML,BulkColumn) as BulkColumn
FROM OPENROWSET (BULK '''+#file+''', SINGLE_BLOB) AS t)
INSERT INTO feed.tempXML (title,link,source)
SELECT
title = t.value (''title[1]'', ''NVARCHAR(300)''),
link = t.value (''link[1]'', ''NVARCHAR(300)''),
source = t.value(''(dc:creator)[1]'',''NVARCHAR(30)'')
FROM #xmlFile.nodes(''/rss/channel/item'') AS xTable(t);'
EXEC(#Query)
END
GO

In your case it might be enough to replace the dc: with a wildcard: *:. Assuming your XML is written into an XML file already, you might try as such:
DECLARE #xmlFile XML=
N'<rss xmlns:atom="http://www.w3.org/2005/Atom" xmlns:dc="http://purl.org/dc/elements/1.1/" xml:base="http://talksport.com/rss/sports-news/football/feed" version="2.0">

<dc:creator>talkSPORT</dc:creator>
<guid isPermaLink="false">247276 at http://talksport.com</guid>
</item>
</channel>
</rss>';
SELECT
title = t.value ('title[1]', 'NVARCHAR(300)'),
link = t.value ('link[1]', 'NVARCHAR(300)'),
source = t.value('(*:creator)[1]','NVARCHAR(30)')
FROM #XmlFile.nodes('/rss/channel/item') AS xTable(t);
This will work too:
WITH XMLNAMESPACES('http://purl.org/dc/elements/1.1/' AS dc)
SELECT
title = t.value ('title[1]', 'NVARCHAR(300)'),
link = t.value ('link[1]', 'NVARCHAR(300)'),
source = t.value('(dc:creator)[1]','NVARCHAR(30)')
FROM #XmlFile.nodes('/rss/channel/item') AS xTable(t);
And you can declare the namespace within .value too:
SELECT
title = t.value ('title[1]', 'NVARCHAR(300)'),
link = t.value ('link[1]', 'NVARCHAR(300)'),
source = t.value('declare namespace dc="http://purl.org/dc/elements/1.1/";(dc:creator)[1]','NVARCHAR(30)')
FROM #XmlFile.nodes('/rss/channel/item') AS xTable(t);
