Read xml attribute problem in Flash MX

I would like to read the xml below, is anybody able to adjust the actionscript below to read the attribute Header?

[font=Courier New][color=#ff0000]-[/color][/font] [color=#0000ff]<[/color][color=#990000]Events[/color][color=#0000ff]>[/color]
[color=#0000ff]<[/color][color=#990000]Event[/color] [color=#990000]Header[/color][color=#0000ff]=“Header 1[/color][color=#0000ff]” [/color][color=#990000]Content[/color][color=#0000ff]=“Content 1[/color][color=#0000ff]”[/color][color=#0000ff]/>[/color]
[color=#0000ff]</[/color][color=#990000]Events[/color][color=#0000ff]>[/color]

GetTitleText = function(news_xml, entry_index){
var entries = news_xml.firstChild.childNodes;
var title_element = entries[entry_index].firstChild;
return title_element.firstChild.nodeValue;

The below is then being used to get the data into the flash field “title_txt”.
title_txt.htmlText = GetTitleText(news_xml, news_index-1);

Thanks in advance for your help.
