Hi Jorg,
I created a simple test as you recommended, and the results were as I
expected. The CDATA contents were not read. Here is the test:
@Test
Public void testReadCdata(){
Xstream xstream = new Xstream(new StaxDriver());
String contents = "<tag>my data conents</tag>";
String xml = "<string><![CDATA[" + contents + "]]></string>";
String results = (String) xstream.fromXML(xml);
assertEquals(contents, results);
}
"results" is always empty.
I'm using Oracle Java 1.6_033.
I also wrote a test to write "CDATA" and it is always encoding "<" & ">"
characters like "lt&;", etc.
What am I doing wrong?
