returning null while convert to JSON

[Souras]

Hi,
Thanks for x2js,

I am trying to convert the below XML content to JSON using "xml_str2json" but returning null.

<item> <category>Scarlett Johansson</category> <category>Movies</category> <category>Entertainment</category> <merlin:image orientation="landscape">omNMmo6Ony6</merlin:image> </item>

when I am removing <merlin:image... line it is working fine. So, tell what should I do to convert the above structure into JSON.

workZonesController.js:112 Uncaught TypeError: Cannot read property 'Root_tag' of null
at FileReader.reader.onloadend
