http://nagoya.apache.org/bugzilla/show_bug.cgi?id=22054 It's possible to create a text node with a null byte, resulting in erratic behavior ------- Additional Comments From [EMAIL PROTECTED] 2003-08-04 09:05 ------- Comment: Shouldn't Xerces always encode binary characters? However, throwing an exception on parse and not on createTextNode() seems inconsistent to me. If it does not throw an exception on createTextNode() then it should encode the null-byte (like it does with "<", ">" and so on). 2nd Test case: Here comes the test case where you can see that the XML is corrupted. First, an invalid XML is constructed and then saved to disk with Xalan. In the file, you can see that the null-byte has been encoded correctly, but the CDATA section is destroyed. Finally, the invalid XML is being serialized which results in the same error as in the first test case. So, you can construct an invalid XML, but you cannot serialize it. Saving it with Xalan reveals that it is corrupted. Xerces should either encode the null-byte (or other binary chars) or it should throw an exception on createTextNode(),like it does on parse(). Silently constructing an invalid XML is not OK in my opinion.
