parse and process HTML/XML/plain text page

Hi this is my first question here so please bare with me

I am creating a small php app that pulls data from a remote website its working great but i would like to make it more user friendly now.

I need to get a few specific items from the page and as far as i can tell the page looks like an xml file wen you look at sorce code but it has no style to it and appears as plain text so i dont really know what todo

the page i am trying to get looks like this

    <channel>
      <name>data</name>
      <id>data</id>
      <img>data</img>
      <auther>data</auther>
      <mp3>data</mp3>
      <bio>data</bio>
   </channel>
    <channel>
      <name>data</name>
      <id>data</id>
      <img>data</img>
      <auther>data</auther>
      <mp3>data</mp3>
      <bio>data</bio>
   </channel>
    <channel>
      <name>data</name>
      <id>data</id>
      <img>data</img>
      <auther>data</auther>
      <mp3>data</mp3>
      <bio>data</bio>
   </channel>
    <channel>
      <name>data</name>
      <id>data</id>
      <img>data</img>
      <auther>data</auther>
      <mp3>data</mp3>
      <bio>data</bio>
   </channel>

I need to get all the data from each tag under the channel tag and keep it in the same order to echo it back out onto my own page in the same way.

How could i do this ? i tried using regex with the following patter

    $pattern = '<channel>
      <name>(.*)</name>
      <id>(.*)</id>
      <img>(.*)</img>
      <auther>(.*)</auther>
      <mp3>(.*)</mp3>
      <bio>(.*)</bio>
   </channel>';

but that dosent work i really need the best and simplest way todo this thanks.
