XML Schema validation corrupts CDATA sections
---------------------------------------------
Key: XERCESJ-1052
URL: http://issues.apache.org/jira/browse/XERCESJ-1052
Project: Xerces2-J
Type: Bug
Versions: 2.6.2
Environment: Tested with Sun JDK 1.5.0.02 on x86 Linux.
Xerces was built using 'jar-dom3' target.
Reporter: Bas de Bakker
Parsing a document with XML Schema validation messes up CDATA sections. Below
is a self-contained test case.
The output of the test is:
Child 1 = 'foo'
Child 2 = ' bar'
Notice that the space has become part of the CDATA section.
