Re: XML Output Format (Instead of using XMLSerializer, use identity transformer)

Note: XMLSerializer is usually not what you want to use, unless you really
know you want to use it.  We need better doc on identity transformers,
which let you transform any type of source into any type of result -
basically changing the data format (DOM tree, SAX events, Stream) into
another type, but without changing the content.

See http://xml.apache.org/xalan-j/usagepatterns.html#serialize  Or, Edwin

For a while I'm trying to read an xml-file
into dom - transforming it using xalan and
modifying it also. after that i want to
write the "new" dom to a file. All works
fine but of formatting the output. There
are no linebreaks after each tag and some-
times tags are "broken". What am I done
wrong??

try {

          formatt.setIndent(6);
          XMLSerializer serializer = new XMLSerializer(out, formatt);

     try {
          serializer.serialize(doc.getDocumentElement());
          }
          catch (IOException ex) {
                              ex.printStackTrace();
                         }
     out.toString();
     out.close();
etc.

Thanks. I alsy like to use the most universal code. But transformer fails for
streaming out in my case. It hangs like in an infinite loop and goes out of
memory. I reported this error previously.
