OPC Data Client is a toolkit for rapid OPC UA, DA, AE and XML-DA client application development. It increases your productivity as a developer by virtually eliminating the need to learn the low-level aspects of OPC specifications.
In our blog series on XML Data Integration, OPC Data Client was detailed as the best method for implementing XML to OPC integration in a custom developed application.
Request access to the sample code referenced in those blog posts so you can have a closer look and get starting integrating your own XML data using the OPC Data Client.
