| /** |
| * |
| * This simplistic sample illustrates how an XML application can use |
| * the SAX entityResolver handler to provide customized handling for |
| * external entities. |
| * |
| * It registers an entity resolver with the parser. When ever the parser |
| * comes across an external entity, like a reference to an external DTD |
| * file, it calls the 'resolveEntity()' callback. This callback in this |
| * sample checks to see if the external entity to be resolved is the file |
| * 'personal.dtd'. |
| * |
| * If it is then, it redirects the input stream to the file 'redirect.dtd', |
| * which is then read instead of 'personal.dtd'. |
| * |
| * If the external entity to be resolved was not the file 'personal.dtd', the |
| * callback returns NULL indicating that do the default behaviour which is |
| * to read the contents of 'personal.dtd'. |
