Problem with DOMWriter output for CDATA node
I'm having a problem where DOMWriter is not handling CDATA sections as I
expected. I've search through bugzilla, and not found anything like my
problem.
Here's whats happening. First, I get a DOMDocument by parsing this xml:
<?xml version="1.0" encoding="US-ASCII" standalone="no" ?>
<TestXML>
<Test2>
<![CDATA[Here's data that includes xml-like stuff( <, >, etc. )]]>
</Test2>
</TestXML>
Then, I get a DOMWriter object, and call writeNode, passing in the
DOMDocument from the parser. Here is the xml I get from that:
<?xml version="1.0" encoding="US-ASCII" standalone="no" ?>
<TestXML>
<Test2>
<![CDATA[Here's data that includes xml-like stuff( <, >, etc. )]]>
</Test2>
</TestXML>
My problem is that the left angle bracket was changed to "<", which
would be fine, if it wasn't in a CDATA section. Note that the right angle
bracket came though unchanged.
Here's the code I used to call DOMWriter::writeNode:
void XMLDocument::getXML( char *&xml,
const char *encoding,
bool readable )
{
DOMImplementationLS *impl =
DOMImplementationRegistry::getDOMImplementation( LS );
DOMWriter *writer = impl->createDOMWriter();
// force pretty print:
if (writer->canSetFeature( XMLUni::fgDOMWRTFormatPrettyPrint, true ) )
{
writer->setFeature( XMLUni::fgDOMWRTFormatPrettyPrint, true );
}
// Set the encoding to US-ASCII for now
writer->setEncoding( XMLUni::fgUSASCIIEncodingString );
// create a format target to recieve the resulting XML string
MemBufFormatTarget *target = new MemBufFormatTarget;
// serialize the DOM
writer->writeNode( target, *mDoc );
// make a copy of the result
xml = XMLString::replicate( ( const char * )target->getRawBuffer() );
}
I'm using Xerces-C++ 2.1, with the binaries downloaded from the Apache
site. My code was compiled with MS VC++ 6.0.
I'm pretty new at this, and expect that I've just misunderstood something.
Any help is appreciated!

I think this is fixed in Xerces-C++ 2.2. Please try again and let us know
if problem persists.
