The second parameter (</Place>) is redundant, so you need only one parameter. Also, it is easier if you just pass "Place" rather than "<Place>". Assuming so, here is an example of how you can query:DECLARE @param VARCHAR(32) SET @param = 'Place'DECLARE @x XML;SET @x = '<Person>John Doe</Person> <Place>Seattle, WA</Place>';SELECT c.query('.')FROM @x.nodes('/*[local-name() = sql:variable("@param")]') T(c)This should work in SQL 2005 and above - I am not familiar with the capabilities of Sql XML in SQL 2000, so the this may not work on SQL 2000. |

Hold the phone a minute. Let's find something out, first. - Are you saying that you have a file on the disk that you'd first like to import into SQL Server?
- Are you really using SQL Server 2000 for this?

| SQL Server and T-SQL may not be the best tool for the job if your objective is to parse files and extract data. If you don't need the results in a T-SQL script, consider using a .Net program. If you do need to get the result inside a T-SQL script, you would need to import the file into a database table using BCP, SSIS or other similar tools and then query against that table. Other alternatives might be to use a CLR stored proc, or xp_cmdshell in combination with a .Net program. |

You first say it's not an XML file and then you say it is. Which is it? It would be better if you posted more complete code so we can tell.--Jeff Moden
