CDATA not closed when serializing a DocumentFragment
----------------------------------------------------
Key: XERCESJ-1216
URL: http://issues.apache.org/jira/browse/XERCESJ-1216
Project: Xerces2-J
Issue Type: Bug
Components: Serialization
Affects Versions: 2.7.1, 2.8.1
Reporter: Ricardo Amador
org.apache.xml.serialize.XMLSerializer merges a sequence of CDATA/Text nodes
started by a CDATA node into a single CDATA, no problem here (although I wasn't
expecting it). The problem occurs when this sequence is placed in the end of a
DocumentFragment and you serialize it. The CDATA section is not properly
closed. For instance the following code writes 'txt.<![CDATA[.cdt..txt..cdt.'
instead of '.txt.<![CDATA[.cdt..txt..cdt.]]>':
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document d = db.newDocument();
DocumentFragment df = d.createDocumentFragment();
df.appendChild(d.createTextNode(".txt."));
df.appendChild(d.createCDATASection(".cdt."));
df.appendChild(d.createTextNode(".txt."));
df.appendChild(d.createCDATASection(".cdt."));
XMLSerializer ser = new XMLSerializer(System.out, new OutputFormat());
ser.serialize(df);
It is possible to work around this problem by subclassing XMLSerializer in the
following manner:
public class XMLSerializer extends org.apache.xml.serialize.XMLSerializer {
public XMLSerializer() { super(); }
public XMLSerializer(OutputFormat arg0) { super(arg0); }
public XMLSerializer(Writer arg0, OutputFormat arg1) { super(arg0,
arg1); }
public XMLSerializer(OutputStream arg0, OutputFormat arg1) {
super(arg0, arg1); }
public void serialize(DocumentFragment df) throws IOException {
super.serialize(df);
ElementState state = getElementState();
if (state.inCData && !state.doCData) {
// CDATA properly closed, but still open in the Printer
_printer.printText( "]]>" );
state.inCData = false;
_printer.flush();
if ( _printer.getException() != null )
throw _printer.getException();
}
}
}
