XML File Writer Output Adapter Sample

About This Sample

This sample demonstrates the usage of the TIBCO StreamBase® XML File Writer adapter, which is an embedded adapter suitable for streaming tuples to a text file formatted with XML tags.

The XML file created by this adapter does not contain a root node. Each tuple streamed by the adapter should be treated as an individual document. Input fields of type list or tuple are not supported.
