public class XmlChooser
extends IdvChooser
implements java.awt.event.ActionListener

This handles a variety of flavors of xml documents (e.g., thredds query capability, thredds catalogs, idv menus) to create data choosers from. It provides a combobox to enter urls to xml documents. It retrieves the xml and creates a XmlHandler based on the type of xml. Currently this class handles two types of xml: Thredds catalog and Web Map Server (WMS) capability documents. The XmlHandler does most of the work.

This class maintains the different xml docs the user has gone to coupled with the XmlHandler for each doc. It uses this list to support navigating back and forth through the history of documents.
