Configure this transformer, possibly passing to it a jtidy configuration file location.

 public  void endElement(String uri,
    String name,
    String raw) throws SAXException 
{
        if (this.tags.containsKey(name)) {
            String toBeNormalized = this.endTextRecording();
            try {
                this.normalize(toBeNormalized);
            } catch (ProcessingException e) {
                e.printStackTrace();
            }
        }
        super.endElement(uri, name, raw);
}

React on endElement calls that contain a tag to be tidied and run Jtidy on it, otherwise passthru.

    Map objectModel,

        }

        StringTokenizer tokenizer = new StringTokenizer(tagsParam, ",");
        while (tokenizer.hasMoreElements()) {
            String tok = tokenizer.nextToken().trim();
            this.tags.put(tok, tok);
        }
}

Setup this component, passing the tag names to be tidied.

        super.startElement(uri, name, raw, attr);
		if (this.tags.containsKey(name)) {
            this.startTextRecording();
        }
}

Start buffering text if inside a tag to be normalized, passthru otherwise.
