sp_xml_removedocument (Transact-SQL)

Removes the internal representation of the XML document specified by the document handle and invalidates the document handle.

A parsed document is stored in the internal cache of SQL Server. The MSXML parser (msxmlsql.dll) uses one-eighth the total memory available for SQL Server. To avoid running out of memory, run sp_xml_removedocument to free up the memory.
