Getting multiple values from same xml column in SQL Server - sql-server

Question

I want to get the values from same xml node under same element.
Sample data:
I have to select all <award_number> values.
This is my SQL code:
DECLARE #xml XML;
DECLARE #filePath varchar(max);
SET #filePath = '<workFlowMeta><fundgroup><funder><award_number>0710564</award_number><award_number>1106058</award_number><award_number>1304977</award_number><award_number>1407404</award_number></funder></fundgroup></workFlowMeta>'
SET #xml = CAST(#filePath AS XML);
SELECT
REPLACE(Element.value('award_number','NVARCHAR(255)'), CHAR(10), '') AS award_num
FROM
#xml.nodes('workFlowMeta/fundgroup/funder') Datalist(Element);
Can't change this #xml.nodes('workFlowMeta/fundgroup/funder'), because I'm getting multiple node values inside funder node.
Can anyone please help me?

Answer 1

Since those <award_number> nodes are inside the <funder> nodes, and there could be several <funder> nodes (if I understood your question correctly), you need to use two .nodes() calls like this:
SELECT
XC.value('.', 'int')
FROM
#xml.nodes('/workFlowMeta/fundgroup/funder') Datalist(Element)
CROSS APPLY
Element.nodes('award_number') AS XT(XC)
The first .nodes() call gets all <funder> elements, and then the second call goes into each <funder> element to get all <award_number> nodes inside of that element and outputs the value of the <award_number> element as a INT (I couldn't quite understand what you're trying to do to the <award_number> value in your code sample....)

Answer 2

Your own code was very close, but
You are diving one level to low
You need to set a singleton XPath for .value(). In most cases this means a [1] at the end)
As you want to read many <award_number> elements, this is the level you have to step down in .nodes(). Reading these element's values is easy, once you have your hands on it:
SELECT
REPLACE(Element.value('text()[1]','NVARCHAR(255)'), CHAR(10), '') AS award_num
FROM
#xml.nodes('/workFlowMeta/fundgroup/funder/award_number') Datalist(Element);
What are you trying to do with the REPLACE()?
If all <arward_number> elements contain valid numbers, you should use int or bigint as target type and there shouldn't be any need to replace non-numeric characters. Try it like this:
SELECT Element.value('text()[1]','int') AS award_num
FROM #xml.nodes('/workFlowMeta/fundgroup/funder/award_number') Datalist(Element);
If marc_s is correct...
... and you have to deal with several <funder> groups, each of which contains several <award_number> nodes, go with his approach (two calls to .nodes())
