Re^4: Is there any XML reader like this? (XML::Simple beats LibXML hands down in the speed stakes!)by BrowserUk (Pope)

And that's not even mentioning the fact that XML::LibXML is 20x faster
BTW. Even that factually correct claim only tells half the story. Generate a simple and fairly modest XML file using this:
Now run XML::Simple & XML::LibXML scripts that parse that file and iterate the contents and time them:
All the time you gained during parsing, you throw away four-fold when accessing the data through the nightmare interface of OO baloney.
And if you double the file size:
And now LibXML takes 8 times as long:
Increase the file size 10-fold and LIbXML will take 100 time longer.
Now look carefully at the split times. XML::Simple's parsing time is slow, but linear with the file size. It's traversal time is extremely fast and also linear.
Conversely, LibXML's parsing time is very fast and linear; but it's traversal time is horribly slow and quadratic with the file size.
It is easy to see which one wins in the speed stakes.
