Extract Binary XML data to readable XML file

I am working in PerformancePoint, and the application stores important data in a binary Blob field in a SQL 2005 table.  If I know the specific field name that I am searching for I have been able to extract data from this field as in the code snippet.  However, now I need to search the entire field for data, but I do not know where it might be stored.  

I would like to convert the entire field into an XML document.  Is this possible without knowing all of the tags used in the field?  
DECLARE @xmlblob xml
SELECT
      @xmlblob = CAST(CAST ( ba.xmlblob AS varbinary(MAX)) as xml)
FROM BizAppNodes ba
WHERE VersionEndDateTime = '9999-12-31 00:00:00.000'
AND BizAppNodeLabel = 'Application' 
a
 
SELECT DISTINCT
      tab.col.value('../../@Label', 'varchar(30)') as ModelLabel,
                  tab.col.value('@Server', 'varchar(30)') as CurrentPeriodId
                  FROM @xmlblob.nodes ('/BizModelSite/Models/ArrayOfBizModel/BizModel/EffectiveDatedCurrentPeriods/EffectiveDatedCurrentPeriod') as tab(col)

Your @xmlBlob should have your XML.  Not sure what the question is.

Are you asking how to search the extracted XML not knowing the structure?

Yes exactly.  as it is stored as <Binary data>, I cannot just review it.  I was hoping to extract the full content off to a document so I could more easily perform searches on it.

Your @xmlBlob will contain the entire document.

Just do a select @XMLBlob:


DECLARE @xmlblob xml
SELECT
      @xmlblob = CAST(CAST ( ba.xmlblob AS varbinary(MAX)) as xml)
FROM BizAppNodes ba
WHERE VersionEndDateTime = '9999-12-31 00:00:00.000'
AND BizAppNodeLabel = 'Application'

select @xmlBlob

All it gives me is a single row with a NULL.

try removing one or both of your criteria.  That date doesn't seem valid to me.
