Nested Data Providers

Besides the data providers that get your data, there also data providers that can nest another data provider.
There is a nesting data provider to apply XSL transformation, XML Schema Validation, to support caching the resultset in various scopes or to combine multiple results from different data providers into one.
All the functionality of the Nesting Data Providers are described in this chapter.  

Nesting Data Providers (a.k.a. Filters):

• Cache Filter
• Not Null Filter
• Schema Validation Filter
• Union Filter
• XSL Transformation Filter

Build your own

We think the XML Data Control delivers quite some functionality out of the box.
However, there might be a specific use case in which you need a new sort of data provider. In this case, you can do one of the following two things.
You either try to convince us of the need for this data provider and wait for it or you can build your own.
However, the whole XML Data Control is an open source initiative, but besides that it is also a very plugable framework.
You could extend any part of the XML Data Control and plug in your own functionality.
