The following sections show how you can use Iguana channels to send data in XML format to a web service from Iguana.

To use a channel to send data to a web service, you must:

• Download the SOAPpy library from the iNTERFACEWARE FTP site and install it;
• Use Chameleon to create a VMD file that extracts data from an incoming message and transforms it into XML format;
• Create a second VMD file that calls the web service and sends the XML data to it;
• Create channels in Iguana to receive the data and then send it.

	Note that this example uses one VMD file to transform the message into XML and another VMD file to send the data to the web service. This enables you to change the interface that transforms the message without having to rewrite the Python script that sends the data to the web service.
