SQL string value - sql

Question

Have a large XML file stored in a field within a table, many values have already been extracted and stored in the table, but I'm looking to capture (2) additional: account type = "current" status="X" and account type = "former" status ="Y". In the partial output below there is no former account type so I need a strategy for missing as well.

I'm looking to extract the X value from account type = "current" status="X" and and Y value if an account type = "former" exists. In this case the value 1. added to XML to highlight area of interest. I started by pairing down the data set into a temp table.
select id,
LEFT(SUBSTRING(CreditscoreXML,charindex('<account type="current"',CreditscoreXML),charindex('</account>',CreditscoreXML)),charindex('">',SUBSTRING(CreditscoreXML,charindex('<account type="current"',CreditscoreXML),charindex('</account>',CreditscoreXML)))) [Current_Status]
select
Current_Status, --just so I see output is correct in temp table
substring(Current_Status, charindex('status="',
Current_Status)+8,len(Current_Status)-charindex('status',Current_Status)) [Current_Status]
from #TempCurrent
From here I further tried to refine the text search. Trying to figure out how to eliminate the " after 1 or a better solution to extract both current and former status, former can be missing, need this grouped by Id.
Current Output
Current_Worse_Score Current_Worse_Score Former_Worse
Original Text 1"

Answer 1

Rather than manipulating string data try using the built-in XML functions in SQL Server to make your life easier. For example:
create table dbo.Foo (
id int not null,
bar xml not null
);
insert dbo.Foo (id, bar) values (47, N'<ncf_report xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://cp.com/rules/client">
<!-- the rest of your xml... -->
</ncf_report>')
;with xmlnamespaces(default 'http://cp.com/rules/client')
select
id,
x.a.value(N'#description', N'nvarchar(50)') as [Description],
x.a.value(N'#status', N'nvarchar(50)') as [Status],
x.a.value(N'.', N'nvarchar(50)') as [Account]
from dbo.Foo
cross apply bar.nodes(N'/ncf_report/report/summary/account_status_counters/account[#type="current"]') x(a)
Which yields the result...
id Description Status Account
47 Pays Account as Agreed 1 12

Answer 2

You can use the built-in XML data type methods to query required values from an XML instance which is stored as XMLType column.
DECLARE #X XML;
SET #X = '<ncf_report xmlns:xsd="http://www.w3.org/2001/XMLSchema" ....>'; -- provided XML instance
CREATE TABLE NCFREPORT
(
ncfreportcol XML NOT NULL
);
INSERT INTO ncfreport (ncfreportcol) values (#X); -- inserting the XML instance stored temporarily in above variable X
WITH xmlnamespaces ('http://cp.com/rules/client' as NR)
SELECT T.acc.value('(#status)[1]', 'int') AS Status,
T.acc.value('(#type)[1]', 'varchar(20)') AS AccType,
T.acc.value('(text())[1]', 'int') AS Acc
FROM ncfreport cross apply ncfreport.ncfreportcol.nodes ('/NR:ncf_report/NR:report/NR:summary/NR:account_status_counters/NR:account') as t(acc);
This will result in the following output:
Status AccType Acc
1 current 12
It will produce one row in the output for each account if you have multiple account tags defined in the XML instance. I also noticed that there are missing opening or closing tags in the above XML fragment. It would be a good idea to also have a look at validating the XML before entering into the table. Please have a look at various XML data type methods here - https://learn.microsoft.com/en-us/sql/t-sql/xml/xml-data-type-methods?view=sql-server-ver15
