Failed loading XML... error parsing attribute name attributes construct error Couldn't find end of Start Tag line 1 Extra content at the end of the document

Was receiving this error.
Failed loading XML... error parsing attribute name attributes construct error Couldn't find end of Start Tag line 1 Extra content at the end of the document

I found that this was causing the error, some times extra spaces were being added and causing the above message.
<rss version="2.0"xmlns:atom="http://www.w3.org/2005/Atom">

To fix it I modified the helper file to clean up the url with a preg_replace there is probably a better way with regex but this was fast and worked out of the box for me.

helper.php about line 268

// cleanup the content received
            $repurl= array('<rss version="2.0"xmlns:atom="http://www.w3.org/2005/Atom">');
            $goodurl= array('<rss version="2.0"xmlns:atom="http://www.w3.org/2005/Atom">' =>'<rss version="2.0">');

            $fgcOutput = preg_replace("#(\n|\r|\s\s+|<!--(.*?)-->)#s", "", $fgcOutput);
            $fgcOutput = preg_replace("#(\t)#s", " ", $fgcOutput);

            $fgcOutput = str_replace($repurl, $goodurl, $fgcOutput);
