no propagation of DOCTYPE declaration
Hello,
I am manipulating log4j.xml file programmatically.
- I read a "core" log4j.xml file which contains a DOCTYPE declaration,
aand a basic set of log4j configuration parameters.
- I modify that xml structure
- I then write it out again.
when I write it out, the DOCTYPE declaration has gone.... which means
that log4j complains, and does not get configured properly.
I have tried using all sorts of overly complex DomImplementationImpl
objects to set the DOCTYPE on a new Document, and then append all my
existing xml tree, but still, the DOCTYPE is never there.
I see lots of docs about jDOM having a setDocType() method ...... JAXP
does not seem to have this.
How can I either keep, or append a new DocumentType object, when I write
the DOcument out to file ?
can anyone help ?

you can use JAXP TransformerFactoryImpl [1] to
transform the in memory DOM or SAX events etc. When transforming you should
set the output properties [2] (DOCTYPE_PUBLIC, DOCTYPE_SYSTEM) for a
Transformer [3]
