On the page, you can find a similar function, to generate a sax-event-stream out of a string:
/** * function from joose: http://joose.iki.fi/cocoon/saxInJX.txt */ function stringToSAX( str, consumer, ignoreRootElement ) { var is = new Packages.org.xml.sax.InputSource( new java.io.StringReader( str ) ); var ignore = ( ignoreRootElement == "true" ); var parser = null; var includeConsumer = new org.apache.cocoon.xml.IncludeXMLConsumer(consumer, consumer ); includeConsumer.setIgnoreRootElement( ignore ); try { parser = cocoon.getComponent(Packages.org.apache.excalibur.xml.sax.SAXParser.ROLE ); parser.parse( is, includeConsumer ); } finally { if ( parser != null ) cocoon.releaseComponent( parser ); } } without looking on the details, I just thought, that you can check your function with this function, that was found by joose somewhere in the mailinglist. I use this function in my code and it works. So you have a reference. sry, I have to leave now ...
