The primary goals of this example are to introduce you to the following:

  1. Transforming from CSV to XML.
  2. The Smooks configuration file.
  3. Executing the Smooks Transformation.

Basically, this tutorial illustrates is how to generate a stream of SAX events from a CSV stream and how that stream of SAX events feeds into Smooks to generate an XML model that can be transformed further (in this case it is not).

Transforming from CSV to XML

This is a very simple example that illustrates how Smooks to configure in a non-XML stream parser (CSV) into Smooks.

So here's the source csv file that is to be transformed:


And this is the expected result of our transformation (as generated by the CSVParser):


The Smooks Configuration

We simply specify the CSVParser as the stream parser. More transformation configurations could be added to transform this message further.

Here's the configuration ("smooks-config.xml"):

<?xml version="1.0"?>
<smooks-resource-list xmlns="">

	<!--Configure the CSVParser to parse the message into a stream of SAX events. -->
	<resource-config selector="org.xml.sax.driver">
		<param name="fields" type="string-list">firstname,lastname,gender,age,country</param>


Executing The Transformation

Again, it's exactly the same as with the java-basic tutorial:

Smooks smooks = new Smooks("smooks-config.xml");
StandaloneExecutionContext executionContext = smooks.createExecutionContext();
smooks.filter(new StreamSource(new InputStreamReader(new ByteArrayInputStream(messageIn), "UTF-8")), new StreamResult(writer), executionContext);

Of course, you'd typically cache the Smooks instance.
