Hi,
Thanks for those who helped me with cloning...
I am a little surprised with performance. Maybe there are some basic things
I am doing wrong.
I am parsing a 3 Kb XHTML file and it takes me about 4s, cloning the tree
takes me roughly a ridiculous amount of time (10ms). This on an Athlon XP
1800+ running XP (sure I could switch to Linux but it is not planned for now
:) ).
My code for parsing:
protected void load () {
DOMParser parser;
try {
parser = new DOMParser();
}
catch (Exception e) {
log.severe ("Error: Unable to instantiate parser");
return;
}
try {
parser.parse(m_file.toURI().toString());
m_document = parser.getDocument();
}
catch (SAXParseException e) {
// ignore
}
catch (Exception e) {
String msg;
msg = ("Error: Parse error occurred, " + e.getMessage());
if (e instanceof SAXException) {
e = ((SAXException)e).getException();
}
msg += '\n' + e.toString();
log.severe (msg);
}
}
Questions:
1/ is static'ing my parser will enhance the process?
2/ can I "pre" create some objects I can reuse?
3/ are there some eventual verification I can turn off?
My code for cloning:
public Object clone() {
XHTML11Window win = new XHTML11Window(m_file);
win.m_document = new DocumentImpl();
win.m_document.importNode(m_document.getDocumentElement(), true);
return win;
}
I haven't checked that they really were cloned, but it looks as if they
were...
Any tips are more than welcome!
