I will handle a huge XML file and I will go with XMLReader. Below are three ways to go with, but I need to know which one is the fastest. How can I know this? The planet.xml file is located at http://trash.chregu.tv/planet-big.xml.bz2 in case hat you may need it. Thank you!

Solution:
I haven't worked with XML much in PHP, but if you're dealing with a really large file, a streaming parser is the way to go. Reading the whole thing into memory and building a DOM tree is pretty expensive (and may even fail, if the document's too big to hold in memory).
