In Cocoon scratchpad there's a Transformer that tries in his way to shield the programmer from the SAX events. An example of a class using it is: http://cvs.apache.org/viewcvs.cgi/xml-cocoon2/src/scratchpad/src/org/apache/ cocoon/transformation/Chart2SvgTransformer.java?rev=1.1&content-type=text/vn d.viewcvs-markup It uses an Event system: objects register themselves to be notified when there is a certain condition on the SAX pipeline. > the way I'd see it what you need here is > > - an excalibur subproject that provides this delegating sax parser > - a rewrite of excalibur's SAXConfigurationBuilder to use this > - an extension of SAXConfigurationBuilder for JMeter that handles > JMeter's specific use case. > > I don't exactly understand that use case yet though, so I might be > wrong.
