$ Reader = new XMLReader ();
$ Reader-> open ($ indexUrl );
$ CountElements = 0;

While ($ reader-> read ()){
If ($ reader-> nodeType = XMLReader: ELEMENT ){
$ NodeName = $ reader-> name;
}
If ($ reader-> nodeType = XMLReader: TEXT &&! Empty ($ nodeName )){
Switch ($ nodeName ){
Case 'name ':
$ Name = $ reader-> value;
Break;
Case 'channel ':
$ Channel = $ reader-> value;
Break;
Case 'start ':
$ Start = $ reader-> value;
Break;
Case 'duration ':
$ Duration = $ reader-> value;
Break;
}
}
}
$ Reader-> close ();
