How to output a CDATA section from a Sax XmlHandler

Question

This is a followup question of How to encode characters from Oracle to Xml?

In my environment here I use Java to serialize the result set to xml. I have no access to

Answer 1

It is getting escaped because the handler.characters function is designed to escape and the part isn't considered part of the value.

You need to use the newly exposed methods in DefaultHandler2 or use the TransformerHandler approach where you can set the output key CDATA_SECTION_ELEMENTS, which takes a whitespace delimited list of tag names that should output sub text sections enclosed in CDATA.

StreamResult streamResult = new StreamResult(out);
SAXTransformerFactory tf = (SAXTransformerFactory) SAXTransformerFactory.newInstance();
TransformerHandler hd = tf.newTransformerHandler();
Transformer serializer = hd.getTransformer();
serializer.setOutputProperty(OutputKeys.CDATA_SECTION_ELEMENTS, "column");
hd.setResult(streamResult);
hd.startDocument();
hd.startElement("","","column",atts);
hd.characters(asdf,0, asdf.length());
hd.endElement("","","column");
hd.endDocument();
