T-SQL select all XML nodes as rows from RDL data - sql

Question

I'm trying to SELECT from a table containing XML column. I would like to obtain specific node and have a row created for each one.
The XML is directly obtained from Reporting Services database and contains RDL (report) structure. My goal is to display all ‹Textbox›‹Value›example‹/Value›‹/Textbox› values for each report. The location of ‹Textbox› nodes is unpredictable (it can be part of any element somewhere in XML structure).
Below is the current code, but for some reason id doesn't work:
IF object_id('tempdb..#c') IS NOT NULL
DROP TABLE #c
select top 50
path as reportpath
,name as reportname
,convert(xml, convert(varbinary(max), content)) as reportxml
into
#c
from
reportserver.dbo.catalog
where
content is not null
order by creationdate desc
-----------------------------------------
DECLARE #x XML
SELECT #x =
( SELECT
[reportpath]
,[reportname]
,[reportxml].query('
for $a in //../Textbox
return ‹Textbox
valueX="{$a/Value}"
/›
')
FROM #c AS reports
FOR XML AUTO
)
select #x
-----------------------------------------
SELECT [reportpath] = T.Item.value('../#reportpath', 'nvarchar(max)'),
[reportname] = T.Item.value('../#reportname', 'nvarchar(max)'),
value = T.Item.value('#value' , 'nvarchar(max)')
FROM #x.nodes('//reports/Textbox') AS T(Item)
Example below shows sample "Textbox" containg a "Value":
‹RowGrouping›
‹Width›2.53968cm‹/Width›
‹DynamicRows›
‹Grouping Name="matrix1_OperationalWeek2"›
‹GroupExpressions›
‹GroupExpression›=Fields!OperationalWeek.Value‹/GroupExpression›
‹/GroupExpressions›
‹/Grouping›
‹ReportItems›
‹Textbox Name="textbox35"›
‹rd:DefaultName›textbox35‹/rd:DefaultName›
‹Style›
‹BackgroundColor›White‹/BackgroundColor›
‹PaddingLeft›2pt‹/PaddingLeft›
‹PaddingRight›2pt‹/PaddingRight›
‹PaddingTop›2pt‹/PaddingTop›
‹PaddingBottom›2pt‹/PaddingBottom›
‹/Style›
‹ZIndex›8‹/ZIndex›
‹Value›=Fields!OperationalWeek.Value‹/Value›
‹/Textbox›
‹/ReportItems›
‹/DynamicRows›
‹/RowGrouping›
PS I had some trouble with stackoverflow code formatting so I replaced < and > marks with ‹ and ›. Sorry about that.

Answer 1

Based on Bret's Blog ([http://blogs.netconnex.com/2011/05/extracting-ssrs-report-rdl-xml-from.html][1])
and adding the namespace gets you results... I wish I could claim I understand well enough to explain but I mostly find my way by "stumbling" through it.
--================================================
;WITH XMLNAMESPACES (
DEFAULT 'http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition',
'http://schemas.microsoft.com/SQLServer/reporting/reportdesigner' AS rd --ReportDefinition
)
select top 50
c.Path as reportpath
--, c.name as reportname
,t.value('#Name','VARCHAR(100)') as TextboxName
,t.value('data(Paragraphs/Paragraph/TextRuns/TextRun/Value)[1]', 'varchar(max)') as value
from
reportserver.dbo.catalog c
cross apply
(select convert(xml, convert(varbinary(max), content))) as R(reportxml)
cross apply
--Get all the Query elements (The "*:" ignores any xml namespaces)
r.reportxml.nodes('//*:Textbox') n(t)
where
content is not null
and c.Type = 2 -- Reports
order by creationdate desc

Answer 2

This simple XQuery:
for $a in //Textbox
return
<Textbox
valueX="{$a/Value}"
/>
when applied on the provided XML document (namespace definition added to make it well-formed):
<RowGrouping xmlns:rd="rd">
<Width>2.53968cm</Width>
<DynamicRows>
<Grouping Name="matrix1_OperationalWeek2">
<GroupExpressions>
<GroupExpression>=Fields!OperationalWeek.Value</GroupExpression>
</GroupExpressions>
</Grouping>
<ReportItems>
<Textbox Name="textbox35">
<rd:DefaultName>textbox35</rd:DefaultName>
<Style>
<BackgroundColor>White</BackgroundColor>
<PaddingLeft>2pt</PaddingLeft>
<PaddingRight>2pt</PaddingRight>
<PaddingTop>2pt</PaddingTop>
<PaddingBottom>2pt</PaddingBottom>
</Style>
<ZIndex>8</ZIndex>
<Value>=Fields!OperationalWeek.Value</Value>
</Textbox>
</ReportItems>
</DynamicRows>
</RowGrouping>
produces the wanted, correct result:
<?xml version="1.0" encoding="UTF-8"?>
<Textbox valueX="=Fields!OperationalWeek.Value"/>
Therefore, if you cannot get result, your problem is in something else, not in the XQuery code.

I can't test if this works but it should do what you want.
select top 50
path as reportpath
,name as reportname
,n.t.value('Value[1]', 'varchar(max)') as value
from
reportserver.dbo.catalog
cross apply
(select convert(xml, convert(varbinary(max), content))) as c(reportxml)
cross apply
c.reportxml.nodes('//Textbox') n(t)
where
content is not null
order by creationdate desc
