Cannot deal with CDATA sections properly
----------------------------------------
Key: JIBX-73
URL: http://jira.codehaus.org/browse/JIBX-73
Project: JiBX
Type: Bug
Components: core
Versions: 1.0-RC0
Environment: Linux c10-dev73-com2.cnet.com 2.4.20-28.7bigmem #1 SMP Thu Dec 18
11:04:21 EST 2003 i686 unknown
Reporter: Trenton Lipscomb
Priority: Blocker
The version of xpp3.jar in RC0 is pretty old and contains a bug related to
parsing CDATA sections.
1) Create classes, binding, and sample xml file as shown here:
http://jibx.sourceforge.net/start.html
2) Create test harness as shown here
http://jibx.sourceforge.net/runtime.html
import java.io.FileInputStream;
import org.jibx.runtime.BindingDirectory;
import org.jibx.runtime.IBindingFactory;
import org.jibx.runtime.IUnmarshallingContext;
class TestHarness {
public static void main (String[] args) throws Exception {
IBindingFactory bfact = BindingDirectory.getFactory(Customer.class);
IUnmarshallingContext uctx = bfact.createUnmarshallingContext();
Customer theCustomer = (Customer)uctx.unmarshalDocument(new
FileInputStream("customer.xml"), null);
System.out.println("Customer first name was: " + theCustomer.firstName);
}
}
2) Compile classes and bind, as per here:
http://jibx.sourceforge.net/bindcomp.html
% javac -classpath lib/jibx-run.jar:lib/xpp3.jar Customer.java
TestHarness.java
% java -jar lib/jibx-bind.jar binding.xml
3) Run it.
% java -cp lib/jibx-run.jar:lib/xpp3.jar:. TestHarness
Customer first name was: John
4) Edit customer.xml and add a CDATA section and rerun test
<first-name><![CDATA[>>John<<]]></first-name>
java -cp lib/jibx-run.jar:lib/xpp3.jar:. TestHarness
Customer first name was: >>John<<
5) Now add the killer text to the CDATA section. Note this is valid. It'd
be illegal to have "]]>" in there, but we only have ]]. Also note that
having just ]] is okay. It's some combination of the <script> and comment
and ]] that fowls it up.
<first-name><![CDATA[<script><!-- ]] --> </script>]]></first-name>
% java -cp lib/jibx-run.jar:lib/xpp3.jar:. TestHarness
Exception in thread "main" Error parsing document (line 3, col 53)
org.xmlpull.v1.XmlPullParserException: end tag name 'script' must match
start tag name 'first-name' (position: TEXT seen ...<!-- ]] --> </script>...

6) Finally, grap the latest xpp3 implementation (1.1.3.4.M as of 2005-07-06)
from
http://www.extreme.indiana.edu/dist/java-repository/xpp3/distributions/
and rerun the test using the new xpp3 jar.
% java -cp lib/jibx-run.jar:lib/xpp3-1.1.3.4.M.jar:. TestHarness
Customer first name was: <script><!-- ]] --> </script>
