In this scenario, a file message containing people information is split into sub-messages. Each sub-messages is renamed according the city name it contains, and then routed to another endpoint.

The following is the example XML file used in this use case:


A predefined JavaBean, setFileNames, is called by the cSetHeader component used in this use case to define a file name for each message according to the city name it contains. For more information about creating and using JavaBeans, see Talend Studio User Guide.

package beans;

import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.NodeList;

public class setFileNames {
	public String getCityName(Document document) {
		NodeList cities = document.getDocumentElement().getElementsByTagName(
		Element city = (Element) cities.item(0);
		String textContent = city.getTextContent();
			return textContent+".xml";
