I use the following to search for subtitles:
http://www.opensubtitles.org/search/sub ... /simplexml
I realized it doesn't work when only one subtitle is available. Instead of getting the simple xml page it's redirected to a full html page with the subtitle info.
Example:
http://www.opensubtitles.org/search/sub ... /simplexml
That redirects to http://www.opensubtitles.org/en/subtitles/3306847/-en
Is there any way to avoid this behavior?
