RE: how to generate sax events from variables

[Andrew Welch]

Just to finish the thread, heres a working example:

First off (because its shorter) the code for the transformer:

//custom xmlReader that 'fakes' sax events
XMLReader xr = new awXmlReader();

//transformer than can take the sax events           
SAXTransformerFactory stf = 
(SAXTransformerFactory)TransformerFactory.newInstance();
TransformerHandler th = stf.newTransformerHandler(new StreamSource(xsl));

//kick off the transform using a dummy string            
th.setResult(new StreamResult(System.out));
xr.setContentHandler(th);
xr.parse("dummy");

Thats it, quite simple really. The xmlreader is as follows, with no-ops on all 
the methods except parse(String), which reports the fictional elements.
