Hello,

I’m attempting to get some information from SSRS RDL’s.  Is there a way to back up from the current location in an XML document? Given this XML definition fragment;

- <TablixRow> 
  - <TablixCells>
    - <TablixCell>
      - <CellContents>
        - <Textbox Name="PrefFullName">
          - <ActionInfo>
            - <Actions>
              - <Action>
                <Hyperlink>=Fields!ihurl.Value</Hyperlink>

I’ve figured out how to pluck out the <Hyperlink> value, but I cannot figure how to back up to the <Textbox element to get the name. Below is the code that gets Hyperlink. Any help is appreciated.

thanks, beth

  )
select
  a.Server, a.[Report],
  Hyperlink = w.value('(Hyperlink)[1]', 'varchar(100)')
from (
  select
    @@servername as 'Server', [Path] as 'Report',
    cast(cast(c.Content as varbinary(max)) as xml) as 'ContentXML'
  from
    dbo.Catalog c with (nolock)
  where
    c.Content is not null
    and c.ItemID = '[redacted]'
) a
  cross apply ContentXML.nodes(
    '//ActionInfo/Actions/Action'
  ) hl(w)
where
  w.value('(Hyperlink)[1]', 'varchar(100)') is not null
;

The simplest (but not the most efficient) way is to just crawl up the nodes with ../ to move up each level

select
  a.Server, a.[Report],
  Hyperlink = w.value('(Hyperlink)[1]', 'varchar(100)'),
  TextBoxName = w.value('(../../@Name)[1]', 'varchar(100)')

thank you Eddie, that works. I realize it might break if the number of nodes up should change. regards, beth

This should be a bore performant solution

SELECT      Hyperlink = w.value( '(ActionInfo/Actions/Action/Hyperlink/text())[1]', 'varchar(100)' )
          , TextBoxName = w.value('@Name', 'varchar(100)')
FROM        (
              SELECT  ContentXML ...
            )                                                 AS a
CROSS APPLY ContentXML.nodes( '//Textbox' ) AS hl(w)
WHERE       w.value( '(ActionInfo/Actions/Action/Hyperlink/text())[1]', 'varchar(100)' ) IS NOT NULL;
