[xml] encoding fails

[boss gregerhaga net]

<?xml version="1.0" encoding="ISO-8859-1"?>
<rss version="2.0">
   <channel>
      <title>Aftonbladet &#246;jesliv</title>
   </channel>
</rss>

I try to extract the title element from the above. But the encoding is not
recognised. What i get is this:
Aftonbladet öjesliv

here is the code that gets the item:

xmlChar * content_ptr = xmlNodeListGetString(_doc, cur_node->xmlChildrenNode,
0);
if ( !std::strcmp((const char*)cur_node->name, "title") )
                {
                    int len = std::strlen((const char*)content_ptr);;
                    char * t = new char[len+1];
                    std::memcpy( t, content_ptr,  len);
                    FeedInformation->feedContents()->title = t;
                }

advice much appreciated,
thank's,
