How can I get all videos ID's from a Youtube channel

Question

How can I get all video id's from the youtube data feed?

I receive the youtube feed via this (API) URL: http://gdata.youtube.com/feeds/base/users/#userid#/uploads?alt=rss&v=2&orderby=published&client=ytapi-youtube-profile

I already know how to extract the links, descriptions and thumbnails from a Channel, but I want to extract all the video Id's from a Channel (e.g. http://www.youtube.com/watch?v=WWooNnPnHTs)

This is my way. Slow, but it works. :)

function getVideos($channel){
    if($channel == ""){
        return false;   
    }
    /* Get number of videos */
    $books = simplexml_load_file('http://gdata.youtube.com/feeds/base/users/'.$channel.'/uploads?max-results=1&start-index=1');
    $numb_videos = $books->children( 'openSearch', true )->totalResults; 
    settype($numb_videos, "integer");

    $ids = array();
    $i = 1;
    for($i = 1; $i <= $numb_videos; $i++){
        $books = simplexml_load_file('http://gdata.youtube.com/feeds/base/users/'.$channel.'/uploads?max-results=1&start-index='.$i);
        $ApiLink  = $books->entry->id;
        settype($ApiLink, "string");
        $ApiLink = str_replace("http://gdata.youtube.com/feeds/base/videos/", "", $ApiLink);
        array_push($ids, $ApiLink);
    }
    return $ids;    
}
