Bug in Oracle org.w3c.dom.Node ?

Hello,

I am using Oracle 10g for retrieving XML documents as XMLType and
manipulate them in Java, using the method
org.w3c.dom.Node.setTextContent() to set the text child node of a DOM
node. The oracle DOM implementation just appends a child node to the
existing one and does not replace it like it is specified in the
interface documentation of org.w3c.dom.Node

Is this a bug or a feature or am I doing something wrong?

Any help is welcome.

Thank you,
Marvin

Could you maybe post some code?

Here is an example:

----
String xml = "<a><b>1</b></a>";

DocumentBuilderFactory fac = DocumentBuilderFactory.newInstance();
fac.setIgnoringElementContentWhitespace(true);

DocumentBuilder builder;
builder = fac.newDocumentBuilder();

Document doc = builder.parse(new InputSource(new StringReader(xml)));
Node n = doc.getElementsByTagName("b").item(0);

n.setTextContent("2");

System.out.println(n.getClass());
System.out.println(n.getTextContent());
----

the output is:

class oracle.xml.parser.v2.XMLElement
12

When I set

System.setProperty("javax.xml.parsers.DocumentBuilderFactory",

"com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl");

the output is:

class com.sun.org.apache.xerces.internal.dom.DeferredElementImpl
2

The latter shows the behaviour like in DOM-Api specified.
I am using Java 1.5.

Thanks,
Marvin
