OPENXML in Postgres

Question

SQLServer has a very useful function called OPENXML. It works is used like this:

DECLARE @idoc int
DECLARE @doc varchar(1000)
SET @doc =\'



        

Answer 1

I'm sure this code can be improved, but this appears to return the same result in Postgres as the code you posted does in SQL Server.

WITH test_xml(data) AS (VALUES
  ('
    
       
          
          
       
    
    
       
          
       
    
    '::XML)
)
SELECT  unnest((xpath('//Customer/@CustomerID', test_xml.data))),
        unnest((xpath('//Customer/@ContactName', test_xml.data)))
FROM test_xml
