This class is used to read XML Catalogs using the SAX. This reader - * has an advantage over the DOM-based reader in that it functions on - * the stream of SAX events. It has the disadvantage - * that it cannot look around in the tree.

- * - *

Since the choice of CatalogReaders (in the InputStream case) can only - * be made on the basis of MIME type, the following problem occurs: only - * one CatalogReader can exist for all XML mime types. In order to get - * around this problem, the SAXCatalogReader relies on a set of external - * CatalogParsers to actually build the catalog.

- * - *

The selection of CatalogParsers is made on the basis of the QName - * of the root element of the document.
