How to convert XML to hash in Rails where empty array and nil values are preserved -

When I convert a XML structure into the hash from the train to Hash.from_xml (@xml) I do not distinguish the parser between the empty arrays and zero values, while the xml shows the nodes that are immediately eliminated from the form of an empty array as \ , e.g. & lt; Audio_languages ​​/ & gt; vs. properties with which the attribute zero = "true" is defined as zero values.

XML structure (which controls how I generate) looks like this:

  & lt; Feedback & gt; & Lt; Medias & gt; & Lt; Media & gt; & Lt; ID & gt; 1 & lt; / Id & gt; & Lt; Name & gt; Media-1 & lt; / Name & gt; & Lt; Audio_languages ​​/ & gt; & Lt; Avg_rating nil = "true" & gt; & Lt; / Avg_rating & gt; & Lt; / Media & gt; & Lt; Media & gt; & Lt; ID & gt; 2 & lt; / Id & gt; & Lt; Name & gt; Media-2 & lt; / Name & gt; & Lt; Audio_languages ​​/ & gt; & Lt; Avg_rating nil = "true" & gt; & Lt; / Avg_rating & gt; & Lt; / Media & gt; & Lt; / Medias & gt; & Lt; / Reaction & gt; Expected output from   
  Hash.from_xml (@xml)  will be:  
  {"response" = & gt; {"Medias" = & gt; {"Media" = & gt; [{"Id" = & gt; "1", "name" = & gt; "Media-1", "audio_languages" = & gt; [], "Avg_rating" = & gt; Niil}, {"id" = & gt; "2", "name" = & gt; "Media-2", "Audio_Languages" = & gt; [], "Avg_rating" = & gt; Instead, I get zero values ​​for  audio_languages ​​ and  avg_rating : ]}}}   
 P> 
  {"response" = & gt; {"Media" = & gt; {"Media" = & gt; [{"Id" = & gt; "1", "name" = & gt; "Media-1", "audio_languages" = & gt; Zero, "AVG_RATING" = & gt; Zero}, {"id" = & gt; "2", "name" = & gt; "media-2", "audio_languages" = & gt; Zero, "AVG_RATING" = & gt; Zero}]}}}    
 
 
 I used the  libxml  and I I have finished parsing the nodes using I if I checked the nodes sign I'm checking to figure out if I want to convert a zero value to an empty array such as
