XmlDataProvider Class
In This Topic
This data provider can be used to access data from XML files. It will not use schema information in XML/XSD files and does not handle constraints. The main purpose of this class is to provide a fast and easy access to nested XML data. This class is serializable.

Remarks
There are a number of ways to influence the data type parsing behavior of the provider. By default, all nodes are typed by their content, i.e. if a node only contains numbers, the resulting field type will be LlFieldType.Numeric. To override this behavior, you may use the PreParseXPathNavigator Event of the provider. Another way is using a specialized attribute as shown in the example XML below.
