Retrieving Soundcloud media URL via PHP CURL?
I'm using the Soundcloud API + PHP to pull information about soundcloud tracks in order to use jPlayer as a mp3 player for playlists. Now, I am able to completely access all the information about the track except the actual link to the mp3, in order to play the track.
According to the API, if the track开发者_高级运维 allows streaming, you just have to cURL the stream URL (ie: http://api.soundcloud.com/tracks/24887826/stream?client_id=xxx).
Now, If I try to cURL that, my results are a simple HTML bit <html><body>You are being <a href="http://ak-media.soundcloud.com/sjkn57c6gAA5.128.mp3?AWSAccessKeyId=AKIAJBHW5FB4ERKUQUOQ&Expires=1318411541&Signature=yaX7Noe%2F8c5dFF0H%2BGfhZ%2FX0130%3D&__gda__=1318411541_6ed9d2af39e51b5f1e94e659eff0495d">redirected</a>.</body></html>.
The link I want is the whole media.soundcloud.com/sjkn57c6gAA5 and that's it. However, if I try to xpath the '//a/@href' I get no results returned. Can anyone point me in to the right direction of how to grab this link so I can generate the appropriate link to the file?
Thanks ahead of time!

If you're using xpath on HTML (not recommended by the way, as HTML is not a subset of XML unless it's XHTML and doesn't require some tags to be closed), shouldn't it be //html/body/a/@href?
Otherwise, you could use a regular expression to extract the URL:
if(preg_match('/href="(.*?)"/', $m)) {
$url = $m[1];
}
Or you could narrow it down to strip the other parts but you need to be very careful, because I doubt the API guarantees the URL will always be of the same format (e.g. the subdomain will always end with media).
