Repeatable unescaping of html content leads to not valid html

Line 1115 in b3e5f32

$data = html_entity_decode($data);

This line leads to invalid HTML for some documents (for example for /edsapi/rest/Retrieve?an=T115986&dbid=dmp) because of double decoding of HTML content (< becomes < inside HTML body).

Looks like there is no reason to decode HTML content here - it is already decoded inside SimpleXML object. The only thing left to decode is the content of the <ephtml> tags which is double encoded.
So, this line should probably be something like this:

$data = preg_replace_callback('/<ephtml>(.*?)<\/ephtml>/m', function($escaped) {
            return html_entity_decode($escaped[0]);
}, $data);
