AddATrip() is the main method in this class, it is called by the DealsFinder class to add <trip>
nodes under the <sell-off> root element.
public void AddATrip(String tripNum,
String region,
String startDate,
String duration,
String location,
String price,
String commission) {
Element trip = myDoc.createElement("trip");
trip.setAttribute("number", tripNum);
trip.setAttribute("region", region);
Element sdate = myDoc.createElement("startdate");
sdate.appendChild(myDoc.createTextNode(startDate));
Element dur = myDoc.createElement("duration");
dur.appendChild(myDoc.createTextNode(duration));
Element loc = myDoc.createElement("location");
loc.appendChild(myDoc.createTextNode(location));
Element pr = myDoc.createElement("price");
pr.setAttribute("commission", commission);
pr.appendChild(myDoc.createTextNode(price));
trip.appendChild(sdate);
trip.appendChild(dur);
trip.appendChild(loc);
trip.appendChild(pr);
docElement.appendChild(trip);
}
The writeDOMTree() method uses the DOMWriter class to create an XML document in a String
representing the tree.
public void writeDOMTree(PrintWriter out) {
try {
DOMWriter.print(out, myDoc);
} catch (Exception e) { e.printStackTrace(); }
}
}
