I am new to actionscript. Can anyone help me to try getting the values from the XML in the following timed text format :

<?xml version="1.0" encoding="UTF-8"?>
<tt xml:lang="en"
    xmlns:tts="http://www.w3.org/2006/10/ttaf1#styling"
    xmlns:ttm="http://www.w3.org/2006/10/ttaf1#metadata"
    xmlns:smpte="http://www.smpte-ra.org/schemas/2052-1/2010/smpte-tt"
    xmlns:m608="http://www.smpte-ra.org/schemas/2052-1/2010/smpte-tt#cea608">
   <head>
      <ttm:title>SCCconvert </ttm:title>
      <ttm:desc>converted document; </ttm:desc>
      <ttm:copyright>Copyright (C) Computer Prompting and Captioning Co.</ttm:copyright>
      <styling>
      <style xml:id='basic' tts:color='white' tts:fontFamily='proportionalSansSerif' 
            tts:lineHeight='8%' 
            tts:fontSize='8%' 
            tts:fontWeight='bold'
            tts:textOutline='black 8% 8%' />
      </styling>
      <layout>
         <region xml:id='pop1' tts:backgroundColor='transparent'></region>
         <region xml:id='pop2' tts:backgroundColor='blue'></region>
       </layout>
   </head>
   <body>
      <div>
         <p region='pop1' style='basic' xml:space='preserve' begin='00:00:02:05' end='00:00:06:16' tts:origin='47% 10%'>
            <span>♫</span>
         </p>
         <p region='pop1' style='basic' xml:space='preserve' begin='00:00:06:16' end='00:00:08:05' tts:origin='27% 84%'>
            <span>I can&apos;t do this!</span>
         </p>
         <p region='pop2' style='basic' xml:space='preserve' begin='00:00:08:05' end='00:00:09:17' tts:origin='10% 78%'>
            <span>You fail because</span>
         </p>
        </div>
   </body>
</tt>

I can read the XML values if it is in normal form. But I need to display the values in the styles mentioned in the <layout> section

    It’s because your attributes are prefixed by a namespace so you have to create a new namespace for ttm, tts etc… and then use it to access the attribute.

    Example for accessing all backgroundColor inside layout.region node:

    // namespace creation for tts
var tts:Namespace=new Namespace("http://www.w3.org/2006/10/ttaf1#styling");

// and use of the namespace tts for accessing the attribute
// @my_namespace::my_attribute
trace(xml..layout.region.@tts::backgroundColor.toXMLString());
