Hi, I've one of these very pretty DataSet instances. But I don't want to use SQLs select syntax to query my DataSet, I want to use XPath. Therefore I attach my DataSet to an XmlDocument and use SelectSingleNode or even the methods of IXPathNavigator. But what does this cost with respect to performance and memory consumption? What is faster - DataTable.Select or XmlDocument.SelectNode/SelectSingleNode?
Who can enlighten me? Torsten
