The issue as I understand it is ...
Instead of building the model totally in memory and writing it, which
could potentially be expensive, the XMLWriter also supports writing
the information bit by bit with the bonus that the output can formatted
and that characters are substituted.
You could according to the API use the openElement and
closeElement methods to stream the element tags.
The following code for instance should be a lot less memory
expensive:
<code>
XMLWriter xmlWriter = new XMLWriter( writer, OutputFormat.createPrettyPrint());
Namespace ns = DocumentHelper.createNamespace( "tst", "http://www.tst.com/";);
QName rname = DocumentHelper.createQName( "root", ns);
Element root = DocumentHelper.createElement( rname);
xmlWriter.writeOpen( root);
QName ename = DocumentHelper.createQName( "element", ns);
for ( int i = 0; i < 1000; i++) {
Element element = DocumentHelper.createElement( ename);
element.addAttribute( "id", ""+i);
xmlWriter.writeOpen( element);
xmlWriter.writeClose( element);
}
xmlWriter.writeClose( root);
xmlWriter.flush();
xmlWriter.close();
</code>
However this does not at the moment handle namespaces correctly.
