How to output a CDATA section from a Sax XmlHandler
java, sax, xml
Solution
It is getting escaped because the handler.characters function is designed to escape and the `<![CDATA[` 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();
Problem
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 the output stream itself, only to a org.xml.sax.ContentHandler. When I try to output characters in a CDATA Section: It happens basically like this: ``` xmlHandler.startElement(uri, lname, "column", attributes); String chars = "<![CDATA["+rs.getString(i)+"]]>"; xmlHandler.characters(chars.toCharArray(), 0, chars.length()); xmlHandler.endElement(uri, lname, "column"); ``` I get this: ``` <column><![CDATA[33665]]></column> ``` But I want this: ``` <column><![CDATA[33665]]></column> ``` So how can I output a CDATA section with a Sax ContentHandler?
