[CDATA] not the same way read in DOM and SAX (DOM: O.K., SAX: not O.K.)

Question

I wrote a test application that reads a XML file. First method reads it via DOM in a Document object, second that reads it via SAX in a string. The output is almost the same but the character data is different:
while the dom outout is as expected:
<hap>EUSF</hap>
<name><![CDATA[WADDELL&REED ADV BOND CL Y]]></name>
the SAX output is different:
<hap>EUSF</hap>
<name>WADDELL&REED ADV BOND CL Y</name>
as both elements have text data, only the second is enclosed in a <![CDATA]> value. The DOM output is the same as when displayed the XML in internet explorer, so i guess this is the correct result. but my SAX reader does not display the <![CDATA]> value ...
to get the sax output i subclassed DefaultHandler and overwrote the methods like described in the Web Service Tutorial "Echoing an XML File with the SAX Parser" (http://java.sun.com/webservices/docs/ea2/tutorial/doc/JAXPSAX3.html#64190):
* Overwrites super.
* Receive notification of character data inside an element.
public void characters(char buf[], int offset, int len) {
String s = new String(buf, offset, len);
if (!s.trim().equals("")) { //suppress output of characters that are all whitespace
write(s);
}//characters()
the characters() method has the content of an element, but it has not the information if a CDATA is enclosing the data or not(?). How can this be done?

Answer 1

There's a thing called a LexicalHandler (org.xml.sax.ext.LexicalHandler) that has startCDATA and endCDATA methods. The API documentation suggests that you could create your own LexicalHandler and use it somehow, but it doesn't give you a nicely packaged example. I don't have an example of it either, sorry.
However despite what you say, those two outputs are not different. In XML terms they are identical and parsers will treat them identically.
