Using SAX

[vho]

Hi guys i have this small class task that i'm having trouble with. I need to create a PHP file using SAX to generate the display shown below from an XML file.

 

*** This is the xml source code from which i need to generate the display: ***

    <price>49.99</price>
    <book>

      <standardFeatures oars="plastic" lifeVests="none">false</standardFeatures>

        <author>J.K. Rowling</author>
      </authors>

And.... your question / problem is?

Sorry for being vague but what i know is that it will be parsed through a SAX parser which usually generates a sequence of events. I'm having trouble with the php coding as this is my first class. I have tried reading through w3schools but i'm still having trouble understanding it. if u can give me a nudge in the right direction i'll try take it from there.
