Xml Handler.NET is a library to allow developers to store data as XML-file with out knowledge of XML concepts. Precisely saying, it can act as a middle layer to support Add, Select (with condition), Insert, Update, and Delete operations with Commit and Rollback. Additionally we can set field to DataType, AutoIncrement and KeyField. Actually, the operations are handled by the DataSet, finally stored it as XML file. So, you can expect most of the operations suppoerted by DataSet here. XML Handler.NET is designed to support : squared structure(data table), no attributes, minimal data, read more & write less, portable, simple & easy use. It suffers all the disadvantages of XML as a text-file. More info: www.ideaBubbling.com/XMLHAndler.aspx
