i have set of records from XML type and i need to loop through the Nodes and extract data from them
<Data xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<OP xmlns="http://tempuri.org/Types.xsd">
<ID>
<FDSerial>00000008</FDSerial>
<Type>1</Type>
</ID>
<Param>1</Param>
<OperationName>ReadData</OperationName>
</OP>
<OP xmlns="http://tempuri.org/Types.xsd">
<ID>
<FDSerial>00000009</FDSerial>
<Type>1</Type>
</ID>
<Param>1</Param>
<OperationName>ReadData</OperationName>
</OP>
</Data>
i already read from the record but i need to loop through the Nodes
;WITH XMLNAMESPACES('http://tempuri.org/Types.xsd' as ns)
SELECT Data.value('/Data[1]/ns:Op[1]/ns:ID[1]/ns:FDSerial[1]', 'varchar(50)')
as Serial
FROM [dbo].[DB]
what i need to replace the # 1 with i in a loop
Update:
i updated the xml data.
the expected from this data is the Nodes value of the FDSerial.
i hope i explained my issue clearly
You don't need a loop at all. Use nodes() in a cross apply to shred on /Data/OP.
with xmlnamespaces('http://tempuri.org/Types.xsd' as ns)
select T.X.value('(ns:ID/ns:FDSerial/text())[1]', 'varchar(50)') as Serial
from dbo.DB
cross apply DB.Data.nodes('/Data/ns:OP') as T(X)
this will work also
;WITH XMLNAMESPACES('http://tempuri.org/Types.xsd' as ns)
SELECT Data.value('(Data/ns:Op/ns:ID/ns:FDSerial/text())[1]', 'varchar(50)')
as Serial
FROM [dbo].[DB]

I'm generating XML from a SQL Server table.
This is my code:
;WITH XMLNAMESPACES
(
'http://www.w3.org/2001/XMLSchema-instance' AS xsi
--,DEFAULT 'http://www.w3.org/2001/XMLSchema-instance' -- xmlns
)
SELECT
'T_Contracts' AS "#tableName",
(SELECT * FROM T_Contracts
FOR XML PATH('row'), TYPE, ELEMENTS xsinil)
FOR XML PATH('table'), TYPE, ELEMENTS xsinil
I want the result to look like this (note: attribute tableName on the root element):
<table xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" tableName="T_Contracts">
<row>
<VTR_UID>779FE899-4E81-4D8C-BF9B-3F17BC1DF146</VTR_UID>
<VTR_MDT_ID>0</VTR_MDT_ID>
<VTR_VTP_UID xsi:nil="true" />
<VTR_Nr>0050/132251</VTR_Nr>
</row>
</table>
But it duplicates the XSI namespace on the row element...
<table xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" tableName="T_Contracts">
<row xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<VTR_UID>779FE899-4E81-4D8C-BF9B-3F17BC1DF146</VTR_UID>
<VTR_MDT_ID>0</VTR_MDT_ID>
<VTR_VTP_UID xsi:nil="true" />
<VTR_Nr>0050/132251</VTR_Nr>
</row>
</table>
What's the correct way to add an attribute to the root element, and only the root element ?
Note
NULL-values must be returned as <columnName xsi:nil="true" /> and not be omitted.
(And no xml.modify after the select)
Please note that this is NOT a duplicate of an existing question.
This annoying behaviour of repeated namespaces with sub-queries was a reported issue for more than 10 years on MS-Connect with thousands of votes. This platform was dismissed, so was this issue and there is no perspective that MS will ever solve this.
Just to be fair: It is not wrong to repeat the namespace declaration. It's just bloating the string-based output...
Even stranger is the the unsupported attribute on a root level node...
Well, if you need a head-ache, you might look into OPTION EXPLICIT :-)
The accepted answer by Marc Guillot will not produce xsi:nil="true" attributes as you seem to need them. It will just wrap your result with the appropriate root node.
Finally: This cannot be solved with XML methods, you can try this:
Update: Found a way, see below...
DECLARE #tbl TABLE(ID INT,SomeValue INT);
INSERT INTO #tbl VALUES(1,1),(2,NULL);
SELECT CAST(REPLACE(CAST(
(
SELECT *
FROM #tbl
FOR XML PATH('row'),ROOT('table'),TYPE, ELEMENTS XSINIL
) AS nvarchar(MAX)),'<table ','<table tableName="T_Contracts" ') AS XML);
The result
<table xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" tableName="T_Contracts">
<row>
<ID>1</ID>
<SomeValue>1</SomeValue>
</row>
<row>
<ID>2</ID>
<SomeValue xsi:nil="true" />
</row>
</table>
The idea in short:
We create the XML without a sub-query and add the attribute with a string method into the casted XML.
As the position of an attribute is not important, we can add it everywhere.
alternatively you might search for the first closing > and use STUFF() there...
UPDATE
Heureka, I just found a way, to create this without swithing to string, but it's clumsy :-)
DECLARE #tbl TABLE(ID INT,SomeValue INT);
INSERT INTO #tbl VALUES(1,1),(2,NULL);
SELECT
(
SELECT 'T_Contracts' AS [#tableName]
,(
SELECT 'SomeRowAttr' AS [#testAttr] --added this to test row-level attributes
,*
FROM #tbl
FOR XML PATH('row'),TYPE, ELEMENTS XSINIL
)
FOR XML PATH('table'),TYPE, ELEMENTS XSINIL
).query('<table xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">{/table/#*}
{
for $nd in /table/row
return
<row>{$nd/#*}
{
$nd/*
}
</row>
}
</table>');
The result
<table xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" tableName="T_Contracts">
<row testAttr="SomeRowAttr">
<ID>1</ID>
<SomeValue>1</SomeValue>
</row>
<row testAttr="SomeRowAttr">
<ID>2</ID>
<SomeValue xsi:nil="true" />
</row>
</table>
Why don't you build manually the root element ?
Example:
with CTE as (
select (select * from T_Contracts for xml path('row')) as MyXML
)
select '<table xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" tableName="T_Contracts">' +
MyXML +
'</table>'
from CTE
Unfortunately you cannot do this with the SQL Server out of the box nor exists an elegant way to do that. To alleviate the issue, you can replace NULLs with empty strings. This will remove xmlns, but you have to define your select list explicitly as follows. Moreover, this works only with character string data types as you cannot assign an empty string ('' in ISNULL function) to-for example-an integer.
;WITH XMLNAMESPACES
(
'http://www.w3.org/2001/XMLSchema-instance' AS xsi
--,DEFAULT 'http://www.w3.org/2001/XMLSchema-instance' -- xmlns
)
SELECT 'T_Contracts' AS "#tableName",
(
SELECT
ISNULL(VTR_UID, '') 'row/VTR_UID'
,ISNULL(VTR_MDT_ID, '') 'row/VTR_MDT_ID'
,ISNULL(VTR_VTP_UID, '') 'row/VTR_VTP_UID'
,ISNULL(VTR_Nr, '') 'row/VTR_Nr'
FROM T_Contracts
FOR XML PATH(''), TYPE
)
FOR XML PATH('table'), TYPE, ELEMENTS xsinil
The result will be like below:
<table xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" tableName="T_Contracts">
<row>
<VTR_UID>779FE899-4E81-4D8C-BF9B-3F17BC1DF146</VTR_UID>
<VTR_MDT_ID>0</VTR_MDT_ID>
<VTR_VTP_UID />
<VTR_Nr>0050/132251</VTR_Nr>
</row>
</table>
I have an XML in SQL table column. I need to decode this xml and get value of particular nodes. Find my XML below
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header/>
<SOAP-ENV:Body>

xmlns:ns="http://www.regfrez.com/schemas/service1_V2/SharedResources/XMLSchema/Schema.xsd"
xmlns:tns="http://www.erdeftq.ae/Activematrix/ESB/service1/1_0">
<transactionResponse>
<transaction-info>
<registrationId>R1234</registrationId>
<trialId>T12345</trialId>
<transactionId>12345</transactionId>

<status>Confirmed</status>
</transaction-info>
</transactionResponse>
</ns:createTransactionResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
I need the values of nodes: registrationId, transactionId and status and I tried this but couldn't succeed as i got empty value as result:
DECLARE #xml XML
SET #xml = 'XML here'
SELECT T.C.value('#status', 'nvarchar(100)') FROM #xml.nodes('createTransactionResponse/transactionResponse/transaction-info/status') T(C)
SELECT T.C.value('#trans', 'nvarchar(100)') FROM #xml.nodes('createTransactionResponse/transactionResponse/transaction-info/transactionId') T(C)
SELECT T.C.value('#id', 'nvarchar(100)') FROM #xml.nodes('createTransactionResponse/transactionResponse/transaction-info/registrationId') T(C)
Any help/correction would be appreciated
Your own attempt is ignoring the namespaces and does not specify the full XPath.
Try one of these approaches:
Your XML:
DECLARE #xml XML
SET #xml = '<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header/>
<SOAP-ENV:Body>
<ns:createTransactionResponse
xmlns:impl="http://office/work/services/service1"
xmlns:ns="http://www.regfrez.com/schemas/service1_V2/SharedResources/XMLSchema/Schema.xsd"
xmlns:tns="http://www.erdeftq.ae/Activematrix/ESB/service1/1_0">
<transactionResponse>
<transaction-info>
<registrationId>R1234</registrationId>
<trialId>T12345</trialId>
<transactionId>12345</transactionId>
<transactionDate>27-02-2020:08:47</transactionDate>
<status>Confirmed</status>
</transaction-info>
</transactionResponse>
</ns:createTransactionResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>';
--This is the most explicit (which is always a best way):
WITH XMLNAMESPACES('http://schemas.xmlsoap.org/soap/envelope/' AS n1
,'http://www.regfrez.com/schemas/service1_V2/SharedResources/XMLSchema/Schema.xsd' AS n2)
SELECT #xml.value('(/n1:Envelope/n1:Body/n2:createTransactionResponse/transactionResponse/transaction-info/registrationId/text())[1]','nvarchar(max)') AS RegistrationId
,#xml.value('(/n1:Envelope/n1:Body/n2:createTransactionResponse/transactionResponse/transaction-info/transactionId/text())[1]','nvarchar(max)') AS TransactionId
,#xml.value('(/n1:Envelope/n1:Body/n2:createTransactionResponse/transactionResponse/transaction-info/status/text())[1]','nvarchar(max)') AS [Status];
--This will avoid some repeated XPath, but .nodes() produces quite some overhead:
WITH XMLNAMESPACES('http://schemas.xmlsoap.org/soap/envelope/' AS n1
,'http://www.regfrez.com/schemas/service1_V2/SharedResources/XMLSchema/Schema.xsd' AS n2)
SELECT ti.value('(registrationId/text())[1]','nvarchar(max)') AS RegistrationId
,ti.value('(transactionId/text())[1]','nvarchar(max)') AS TransactionId
,ti.value('(status/text())[1]','nvarchar(max)') AS [Status]
FROM #xml.nodes('/n1:Envelope/n1:Body/n2:createTransactionResponse/transactionResponse/transaction-info') A(ti);
--And this is for lazy people :-)
SELECT #xml.value('(//*:registrationId)[1]','nvarchar(max)') AS RegistrationId
,#xml.value('(//*:transactionId)[1]','nvarchar(max)') AS TransactionId
,#xml.value('(//*:status)[1]','nvarchar(max)') AS [Status];
Hint: The last one (for lazy people) uses the deep search (with //) and uses a wildcard for the namespace. This is very dangerous if the elements might occur more than once within your XML.
The XML you have is pretty complex. You have multiple namespaces, with different nodes using different ones. This means you need to use WITH XMLNAMESPACES to declare all these.
Then you need to use nodes to navigate the to needed node, prefixing them with the appropriate namespaces, till you get to transaction-info. Then you use use value to get the information.
#Status isn't what you're after here, that's for is you have something like <node status=1\>, you need to get the text() value of the node.
This results in the below:
DECLARE #X xml = '<?xml version="1.0" encoding="UTF-8"?>

I have been through the numerous questions on this issue here and none of those resolutions seem to work. I have the following XML:
DECLARE #XML xml;
SELECT #XML ='<?xml version="1.0" encoding="UTF-8"?>
<hb:MedicalAidMessage xmlns:hb="bridge.co.za/mes" Version="6.0.0">
<Claim>
<Details>
<LineItems>
<LineItem>
<HBBatchNum>2414</HBBatchNum>
</LineItem>
</LineItems>
</Details>
</Claim>
</hb:MedicalAidMessage>';
and this code to parse it:
;WITH XMLNAMESPACES ('bridge.co.za/mes' as ns)
SELECT
ISNULL(T.N.value('HBBatchNum[1]', 'INT'), 0) AS BatchNo
FROM
#XML.nodes('/Claim/Details/LineItems/LineItem[1]') AS T(N)
Which is returning a blank value instead of 2414. In the live query the XML is stored in a table column. I just cannot figure out why I am not getting the node value.
It is fairly obvious... Claim is not the root element. So use one of the following:
WITH XMLNAMESPACES ('bridge.co.za/mes' AS ns)
SELECT ISNULL(T.N.value('HBBatchNum[1]', 'int'),0) AS BatchNo
FROM #XML.nodes('/ns:MedicalAidMessage/Claim/Details/LineItems/LineItem[1]') AS T(N)
-- WITH XMLNAMESPACES ('bridge.co.za/mes' AS ns)
SELECT ISNULL(T.N.value('HBBatchNum[1]', 'int'),0) AS BatchNo
FROM #XML.nodes('/*:MedicalAidMessage/Claim/Details/LineItems/LineItem[1]') AS T(N)
I have a SQL Server database table with a column called XML that contains XML data which is structured like this:
<Item xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://test/data">
<Roots>
<Root>
<Name>Field Name</Name>
<Value>Field Value</Value>
</Root>
<Root>
<Name>Field Name</Name>
<Value>Field Value</Value>
</Root>
</Roots>
I want to use T-SQL to get the Value where Name = Total. I have tried the following but it isn't returning any data:
SELECT [XML]
FROM [BusinessAccount]
WHERE [XML].value('(/Root/Name)[13]', 'VARCHAR(MAX)') LIKE '%Total%'
If anyone could tell me where I've gone wrong?
You are missing the required WITH XMLNAMESPACES for your XML and the path is incorrect.
If you want to bring back rows where the 13th element consists of the text Total you can use the below.
WITH XMLNAMESPACES (DEFAULT 'http://test/data')
SELECT [XML]
FROM [BusinessAccount]
WHERE 1 = [XML].exist('(/Item/Roots/Root/Name)[13][text() = "Total"]')
Otherwise you can add the WITH XMLNAMESPACES to your original query and fix the path there too.
You need to specify namespaces. You can then match <Name> and <Value> pairs and extract the contents of <Value> like so:
SELECT NameNode.value('declare namespace x="http://test/data"; (../x:Value)[1]', 'varchar(100)')
FROM [BusinessAccount]
CROSS APPLY [XML].nodes('declare namespace x="http://test/data"; //x:Root/x:Name') AS n(NameNode)
WHERE NameNode.value('.', 'varchar(100)') = 'Total'
Demo on db<>fiddle
I've created a simplified version of my problem:
DECLARE #X XML =
'<Root xmlns="TestNS" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<Test>
<Id>1</Id>
<InnerCollection>
<InnerItem>
<Value>1</Value>
</InnerItem>
<InnerItem>
<Value>2</Value>
</InnerItem>
<InnerItem>
<Value>3</Value>
</InnerItem>
</InnerCollection>
</Test>
<Test>
<Id>2</Id>
<InnerCollection>
<InnerItem>
<Value>5</Value>
</InnerItem>
<InnerItem>
<Value>6</Value>
</InnerItem>
<InnerItem>
<Value>7</Value>
</InnerItem>
</InnerCollection>
</Test>
</Root>'
I'm trying to write a query that takes each <Test> element and breaks it into a row. On each row I want to select the Id and the InnerCollection as XML. I want to create this InnerCollection XML for the first row (Id:1):
<InnerCollection xmlns="Reed.Api" xmlnsi="http//www.w3.org/2001/XMLSchema-instance">
<InnerItem>
<Value>1</Value>
</InnerItem>
<InnerItem>
<Value>2</Value>
</InnerItem>
<InnerItem>
<Value>3</Value>
</InnerItem>
</InnerCollection>
I tried doing that with this query but it puts a namespace I don't want on the elements:
;WITH XMLNAMESPACES
(
DEFAULT 'TestNS'
, 'http://www.w3.org/2001/XMLSchema-instance' AS i
)
SELECT
X.value('Id[1]', 'INT') Id
-- Creates a p1 namespace that I don't want.
, X.query('InnerCollection') InnerCollection
FROM #X.nodes('//Test') AS T(X)
My Google-fu isn't very strong today, but I imagine it doesn't make it any easier that the darn function is called query. I'm open to using other methods to create that XML value other than the query method.
I could use this method:
;WITH XMLNAMESPACES
(
DEFAULT 'TestNS'
, 'http://www.w3.org/2001/XMLSchema-instance' AS i
)
SELECT
X.value('Id[1]', 'INT') Id
,CAST(
(SELECT
InnerNodes.Node.value('Value[1]', 'INT') AS 'Value'
FROM X.nodes('./InnerCollection[1]//InnerItem') AS InnerNodes(Node)
FOR XML PATH('InnerItem'), ROOT('InnerCollection')
) AS XML) AS InnerCollection
FROM #X.nodes('//Test') AS T(X)
But that involves calling nodes on it to break it out into something selectable, and then selecting it back into XML using FOR XML... when it was XML to begin with. This seems like a inefficient method of doing this, so I'm hoping someone here will have a better idea.
This is how to do the SELECT using the query method to create the XML on each row that my question was looking for:
;WITH XMLNAMESPACES
(
'http://www.w3.org/2001/XMLSchema-instance' AS i
, DEFAULT 'TestNS'
)
SELECT
Test.Row.value('Id[1]', 'INT') Id
, Test.Row.query('<InnerCollection xmlns="TestNS" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">{InnerCollection}</InnerCollection>')
FROM #X.nodes('/Root/Test') AS Test(Row)
