Parse an XML value with a colon in SQL Server - sql-server

Question

I need help to parse XML in SQL Server. I need to get "d1p1:Val2" value and concatenation of values for "d2p1:string".
<FirstData xmlns:i="http://www.w3.org/2001/XMLSchema-instance"
xmlns:d1p1="http://XXXXXX" xmlns="http://YYYYYY" i:type="d1p1:StaticInfo">
<Timestamp>0</Timestamp>
<ActionResult i:nil="true" />
<d1p1:Val1 xmlns:d2p1="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
<d2p1:string>1</d2p1:string>
<d2p1:string>2</d2p1:string>
<d2p1:string>3</d2p1:string>
<d2p1:string>4</d2p1:string>
</d1p1:Val1>
<d1p1:Val2>false</d1p1:Val2>
</FirstData>

Answer 1

Your question is not very clear, but this might help you:
DECLARE #xml XML=
N'<FirstData xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns:d1p1="http://XXXXXX" xmlns="http://YYYYYY" i:type="d1p1:StaticInfo">
<Timestamp>0</Timestamp>
<ActionResult i:nil="true" />
<d1p1:Val1 xmlns:d2p1="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
<d2p1:string>1</d2p1:string>
<d2p1:string>2</d2p1:string>
<d2p1:string>3</d2p1:string>
<d2p1:string>4</d2p1:string>
</d1p1:Val1>
<d1p1:Val2>false</d1p1:Val2>
</FirstData>';
WITH XMLNAMESPACES(DEFAULT 'http://YYYYYY'
,'http://XXXXXX' AS d1p1
,'http://schemas.microsoft.com/2003/10/Serialization/Arrays' AS d2p1)
SELECT #xml.value(N'(/FirstData/d1p1:Val2/text())[1]','bit') AS D1P1_Val2
,#xml.query(N'data(/FirstData/d1p1:Val1/d2p1:string/text())').value(N'text()[1]',N'nvarchar(max)') AS AllStrings;
The result
D1P1_Val2 AllStrings
0 1 2 3 4
This is the - not recommended - minimal query:
SELECT #xml.value(N'(//*:Val2)[1]','bit') AS D1P1_Val2
,#xml.query(N'data(//*:string)').value(N'.',N'nvarchar(max)') AS AllStrings;

Answer 2

Try something like this (can't test it myself ) :
SELECT Instructions.query('
declare namespace d1p1="http://XXXXXX";
declare namespace d2p1="http://schemas.microsoft.com/2003/10/Serialization/Arrays";
concat(//d1p1:Val2, " ", //d2p1:string[1]);
')
I think you just have to elaborate a bit on this
