### Adding and Configuring Conditional Branch Nodes in Message Flows

Use a conditional branch node to specify that message processing is to proceed along exactly one of several possible paths, based on a result returned by an XPath condition.

Before you begin

Display the message flow for the desired proxy service. See Constructing Proxy Service Message Flows.

To add a conditional branch node

1. In the Message Flow Design Palette, open the ALSB Message Flow > Nodes list, if it is not already open.
2. Drag the conditional branch node to the desired location in the message flow.

To configure the conditional branch node

1. In the Message Flow Editor, click the conditional branch node, if it is not already selected.
2. On the Conditional Branch Node Properties page, edit properties as appropriate.x
