Creating a W3C DOM tree just to create a dom4j tree seems a bit excessive.
Why not just use the SAXReader?
Also, if ever you have an XML parsing performance problem, try caching the
parser. Often parsers take quite a while to 'warm up' particularly things
like Xerces.
e.g. if using the dom4j SAXReader, it can often be useful to use ThreadLocal
to pool them by thread. e.g.
ThreadLocal pool= new ThreadLocal() {
protected Object initialValue() {
return new SAXReader();
}
};
...
SAXReader reader = (SAXReader) pool.get();
reader.parse( "foo.xml" );
