Detailed Description

Wrapper that translates its content via XSLT. The content must be valid XML for this to work. This is pretty usefull in conjunction with DynaReporter when you want to use one of the zillion PDF libs. You can generate the content via DynaReporter and then transform the content to a form that the PDF lib understands. Most likely this will be much easier than trying to re-generate the report with XML.
Other uses include a simple transformation of the generated front end code to privide for "skinning". As there is only so much you can do with CSS, you might need to structurally change the generated HTML prior to handing it to the client.
Note that XSLT engines vary <emp>greatly</emp> in speed. The default case of using Xalan which is included by WO is probably not the best choice for a site with a little bit of traffic. Therefore there is an option where you can set the transformer factory name to use, you also need to include the corresponding jar into the classpath.

enabled flag that decides if the transformation is applied. If not set, then only the content will be shown. stylesheet name of the XLST stylesheet (mandatory) transformerFactory name of the class for the XSLT transformer factory (optional, defaults to Xalan) framework name of the XLST stylesheet's framework (optional) data will be set to the transformed data (optional) stream will be set to the transformed data (optional) nocache flag that if set creates a new transformer instead of using the one in the cache. Useful when deleloping the stylesheet.
