How to display XML column data - sql

Question

I have a table column consist with the XML files. I want to read XML data and display it.
I come up with the following code. But it read only one row in the column
want to display other XML data also
declare #xml xml
select #xml = event_data_XML from #temp
SELECT * FROM (
SELECT
CAST(f.x.query('data(#name)') as varchar(150)) as data_name,
CAST(f.x.query('data(value)') as varchar(150)) as data_value
FROM #xml.nodes('/event') as t(n)
CROSS APPLY t.n.nodes('data') as f(x)) X
PIVOT (MAX(data_value) FOR data_name IN (NTDomainName, DatabaseName, ServerName)) as pvt
Output should be like this(NTDomainName, DatabaseName, ServerName are xml data)

There are a bunch of ways you could do this. I'll show you a way I think you'd find easiest.
To start, here's a table with a little test data:
CREATE TABLE dbo.stuff (
id int identity (1,1) primary key
, event_data_xml xml
, create_date datetime default(getdate())
, is_active bit default(1)
);
INSERT INTO dbo.stuff (event_data_xml)
VALUES ('<event name="thing" package="as">something</event>')
INSERT INTO dbo.stuff (event_data_xml)
VALUES ('<event name="otherthing" package="as">something else</event>')
---All records
SELECT * FROM dbo.[stuff];
Make sense so far? Here's the query I'd use if I wanted to mix XML data and column data:
---Parsed up
SELECT event_data_xml.value('/event[1]', 'nvarchar(max)') AS [parsed element #text]
, event_data_xml.value('/event[1]/#name', 'nvarchar(max)') AS [parsed attribute value]
, create_date --column from table
FROM dbo.stuff
WHERE is_active = 1;
Using the value() function on the XML column passing in an xpath to what I want to display and SQL Server data type for how I want it returned.
Just make sure you're selecting a single value with your xpath expression.
