XML parsing of large amount of data

Question

Which is the optimal way of XML parsing(XML may be of large amount of data) in php?

Answer 1

If you need a way to parse XML data that is valid for PHP4 too, then you can use the XML parser, or DOM XML (which is a PHP4 only extensions); if you need a solution for PHP5, then you can use DOM, or XMLReader.

It depends from your needs.
