| <s1 title="Log Transformer"> |
| <p>This transformations main purpose is debugging. |
| The <code>LogTransformer</code> is a class that can be plugged into a pipeline |
| to print the SAX events which passes through this transformer in a readable form |
| to a file.</p> |
| <p> |
| The file will be specified in a parameter tag in the sitemap pipeline to the |
| transformer as follows:</p> |
| <source> |
| <map:transform type="log"> |
| <map:parameter name="logfile" value="logfile.log"/> |
| <map:parameter name="append" value="no"/> |
| </map:transform> |
| </source> |
| <p> |
| Because the log file will be hardcoded into the sitemap this LOGTransformer will |
| not be thread save! If you don't specify the logfile the output is send to |
| the standard output of your servlet engine.</p> |
